A complete guide to compensatory and punitive damages in Missouri — categories, caps, evidentiary standards, and strategic considerations
Missouri Injury & Insurance Law | missouriinjuryandinsurancelaw.com
Introduction
Damages are the measure of what a successful plaintiff recovers in a personal injury case. They are also, in most cases, the most important element of case value and the primary battleground at trial. Understanding what Missouri law allows, what it restricts, how each category of damages must be proven, and where the strategic pressure points are is essential to evaluating, developing, and trying a personal injury case effectively.
This post provides a comprehensive treatment of the Missouri damages framework in personal injury cases: the categories of compensatory damages, the evidentiary requirements for each, the collateral source rule and the medical billing write-off problem under § 490.715 RSMo, the eggshell plaintiff doctrine, the caps that apply in specific case types, and the standards and procedures governing punitive damages. It is written as a reference for practicing attorneys and should be verified against current Missouri case law and statutes before reliance in any specific proceeding.
I. Overview of the Missouri Damages Framework
Missouri law divides recoverable damages in personal injury cases into two broad categories: compensatory damages and punitive damages. Compensatory damages are further divided into economic damages — those with an objectively measurable dollar value — and non-economic damages — those that compensate for harms that cannot be precisely quantified. A jury’s award of damages should fairly and reasonably compensate the plaintiff for his or her injury. Stewart v. Partamian, 465 S.W.3d 51, 58 (Mo. 2015). The factors a jury should consider include the nature and extent of injury, diminished earning capacity, the plaintiff’s economic condition and age, and, for non-economic harms, past and future pain, suffering, effect on lifestyle, embarrassment, and humiliation. Id.
| COMPENSATORY DAMAGES — ECONOMIC | COMPENSATORY DAMAGES — NON-ECONOMIC |
| Past medical expenses | Past and future pain and suffering |
| Future medical expenses | Past and future emotional distress |
| Past lost wages and income | Loss of enjoyment of life |
| Future lost earning capacity | Disfigurement |
| Property damage | Disability |
| Other out-of-pocket economic losses | Loss of consortium (spouse’s claim) |
Punitive damages are available in cases of egregious conduct but are subject to significant procedural and substantive requirements under § 510.261 RSMo, as discussed in Section VII. Each category of damages carries its own evidentiary requirements, and failing to satisfy those requirements is one of the most common grounds for a directed verdict or a reduction of the verdict on post-trial motion.
II. Economic Damages
Past Medical Expenses
Past medical expenses are recoverable to the extent the treatment was reasonable, necessary, and proximately caused by the defendant’s negligence. The governing evidentiary framework is now primarily statutory. Under § 490.715.5 RSMo, the parties may introduce evidence of the actual cost of the medical care or treatment — defined as the amount paid by or on behalf of the plaintiff plus any remaining amount necessary to satisfy the provider’s financial obligation after adjustment for contractual discounts, price reductions, or write-offs by any person or entity. § 490.715.5(2) RSMo.
The interplay between billed amounts, insurance write-offs, and actual payments is frequently contested and is addressed in detail in Section IV. Separately, under § 490.710 RSMo, advance or partial payments made by a defendant predicated on possible tort liability constitute a credit deductible from any final settlement or judgment, and evidence of such payments shall not be brought to the attention of the jury. § 490.710(1)-(2) RSMo.
Practice Tip: Expert testimony is commonly required to establish medical causation in contested cases. Lay testimony may suffice in straightforward cases where causation is obvious, but counsel should not assume it will carry the issue where the defense puts on medical evidence.
Future Medical Expenses
Future medical expenses compensate the plaintiff for the cost of care that will be reasonably necessary in the future as a result of the defendant’s negligence. Missouri law permits recovery when future treatment is shown with reasonable certainty, and expert testimony may be used to establish the probability and cost of that care.
As the Missouri Supreme Court has stated: “It is Missouri’s well-settled rule that a plaintiff is entitled to full compensation for past or present injuries that the plaintiff has shown by a preponderance of the evidence were caused by the defendant.” Swartz v. Gale Webb Transp. Co., 215 S.W.3d 127, 130-31 (Mo. 2007). Under Missouri case law, expert testimony is admissible where it addresses the probability, short of reasonable certainty, that future treatment may be necessary and the potential cost of such treatment. Wiley v. Homfeld, 307 S.W.3d 145, 153 (Mo. Ct. App. 2009). Missouri courts permit future medical damages where the evidence shows reasonable medical certainty of future treatment needs, and evidence of future risks created by present injuries is also admissible. Ball v. Allied Physicians Grp., L.L.C., 548 S.W.3d 373 (Mo. Ct. App. 2018); Swartz, 215 S.W.3d at 136. Notably, the § 490.715 limitation on evidence of actual cost does not apply to future medical charges that have yet to occur. Lowe v. Mercy Clinic East Communities, 592 S.W.3d 10 (Mo. Ct. App. 2019).
Future medical expenses must ordinarily be reduced to present value. In medical malpractice cases, § 538.220 RSMo provides for periodic payment of future medical damages, and courts applying that framework must ensure the schedule reflects the full value of the future care — including an appropriate interest rate that will generate sufficient funds over the payment period. Watts ex rel. Watts v. Lester E. Cox Medical Centers, 376 S.W.3d 633 (Mo. 2012).
Practice Tip: In catastrophic injury cases, a life care planner is essential. A life care plan combined with a treating physician’s causation opinion and an economist’s present-value calculation gives the jury an integrated damages package that is difficult for the defense to attack piecemeal.
Past Lost Wages and Income
A plaintiff who was unable to work as a result of the defendant’s negligence may recover wages, salary, and other income lost during the period of disability. Missouri recognizes lost wages as a compensable element of damages, and the plaintiff must prove the amount with reasonable certainty. Past lost wages are calculated from the date of the injury to the date of trial or the date the plaintiff returned to work, whichever is earlier.
Proof of past lost wages typically requires pay stubs, tax returns, employer records, and testimony establishing the plaintiff’s regular earnings and the period during which work was impossible or restricted.
Future Lost Earning Capacity
Where the plaintiff’s injury has permanently or long-term impaired their ability to work and earn income, they may recover for future lost earning capacity. This is distinct from past lost wages: it compensates for the diminished ability to earn, not just specific wages lost. The jury’s consideration of a plaintiff’s damages includes diminished earning capacity as one of the relevant factors. Stewart v. Partamian, 465 S.W.3d at 58. Expert testimony from an economist or vocational rehabilitation specialist is often necessary. Relevant factors include age, education, work history, the nature and permanency of the impairment, and labor market conditions. Future lost earning capacity must be reduced to present value.
Property Damage
Property damage is recoverable where the plaintiff’s property was damaged as a result of the defendant’s negligence. Missouri generally measures property damage by the reasonable cost of repair if the property is repairable, or by the fair market value immediately before the loss if the property is a total loss. Where repair costs exceed the pre-loss fair market value, the plaintiff is generally limited to the pre-loss value. Casada v. Hamby Excavating Co., Inc., 584 S.W.2d 859 (Mo. Ct. App. 1979); McLane v. Wal-Mart Stores, Inc., 10 S.W.3d 669 (Mo. Ct. App. 2000).
III. Non-Economic Damages
Pain and Suffering
Pain and suffering is the most significant non-economic damage category in most personal injury cases. It encompasses both physical pain — the actual sensation of pain caused by the injury and its treatment — and mental anguish — the emotional distress, anxiety, fear, and psychological suffering caused by the injury and its consequences. The jury is allowed to consider intangible or non-economic damages relating to past and future pain, suffering, effect on lifestyle, embarrassment, humiliation, and economic loss in determining its award. Stewart v. Partamian, 465 S.W.3d at 58.
Missouri does not cap pain and suffering damages in general personal injury cases. Medical malpractice cases are subject to a statutory cap on non-economic damages under § 538.210 RSMo, discussed in Section VI. That cap does not apply to personal injury negligence cases outside the medical malpractice context.
Proof of pain and suffering is primarily through the plaintiff’s own testimony, corroborated by medical records documenting the nature and severity of the injury, the treatment required, and the plaintiff’s reported symptoms. Missouri permits lay testimony from family members and friends who observed the plaintiff’s suffering.
Practice Tip: Counsel’s suggestion of a specific damages award during closing argument is not evidence and is not binding on the jury — particularly for pain and suffering, which involves an inherent element of subjective calculation. Stewart v. Partamian, 465 S.W.3d at 59. The jury retains virtually unfettered discretion. An appellate court views the evidence in the light most favorable to the verdict and disregards evidence to the contrary. Id. at 58.
Emotional Distress
Missouri recognizes emotional distress as a component of compensatory damages in personal injury cases where physical injury has occurred. The emotional distress damages include fear, anxiety, depression, and other psychological harm caused by the injury and its consequences. Importantly, there is a low threshold for establishing emotional harm or injury — the law does not require a physical manifestation of harm, and long-term or residual injury is not required. Stone v. Mo. Dep’t of Health & Senior Servs., 350 S.W.3d 14 (Mo. 2011).
Where the plaintiff seeks emotional distress damages beyond what is encompassed within pain and suffering — such as a diagnosed psychiatric condition like post-traumatic stress disorder — expert psychiatric or psychological testimony is typically required to establish diagnosis, causation, and prognosis.
Loss of Enjoyment of Life
Loss of enjoyment of life compensates the plaintiff for the inability to participate in activities and pursuits that were part of life before the injury. Missouri recognizes this as a component of non-economic damages. Proof requires specific evidence of the activities the plaintiff engaged in before the injury and is no longer able to engage in, developed through the plaintiff’s own testimony, family and friend testimony, and records documenting pre-injury activities.
Disfigurement
A plaintiff who has suffered permanent physical disfigurement — such as scarring, deformity, or other permanent alteration in appearance — may recover damages for that disfigurement. The jury may consider the nature, location, and permanence of the disfigurement. Disfigurement damages are supported by photographic evidence, medical testimony describing the nature and permanence of the condition, and the plaintiff’s own testimony about the impact on daily life and self-image.
Disability
Disability damages compensate the plaintiff for the permanent or long-term impairment of physical or mental function caused by the defendant’s negligence. This category overlaps with future lost earning capacity in some respects but is broader — it encompasses the impact on the plaintiff’s ability to function in all aspects of life, not just work. Proof requires medical testimony establishing the nature, extent, and permanence of the plaintiff’s functional limitations. Functional capacity evaluations and vocational rehabilitation assessments are commonly used.
Loss of Consortium
A plaintiff’s spouse may assert a separate claim for loss of consortium — the loss of society, companionship, services, and marital relations caused by the defendant’s negligence. Missouri recognizes loss of consortium as an independent claim belonging to the uninjured spouse. Two causes of action arise when a married person is injured: one for the injured person’s direct losses, and one for the uninjured spouse for loss of the injured person’s services, society, companionship, and sexual relations. Kingman v. Dillard’s, Inc., 643 F.3d 607, 612-13 (8th Cir. 2011) (applying Missouri law).
Missouri courts have recognized a variety of household and domestic duties as belonging to the category of services for whose loss the uninjured spouse may recover, including housework, yard work, and assistance in raising children. Id. at 613. However, the loss of consortium claim does not extend to professional nursing care — a claim for lifelong professional nursing services as consortium recovery would represent an unprecedented expansion of the doctrine that Missouri precedent does not support. Id. at 614. Loss of consortium is available to a spouse but not to children of an injured plaintiff. The claim is derivative: if the injured spouse’s claim fails, the consortium claim fails with it.
There must also be some reasonable relationship between the size of a consortium verdict and that awarded to the injured spouse. The extent of the uninjured spouse’s recovery for loss of consortium depends, in large measure, upon the extent of the injured spouse’s injuries — the consortium claim arises directly from those injuries. Id. at 615.
IV. The Collateral Source Rule and the Medical Billing Write-Off Problem
The collateral source rule generally provides that damages awarded to a plaintiff are not reduced because the plaintiff received compensation for the same injury from an independent source, such as health insurance, disability insurance, or workers’ compensation. The policy rationale is that a defendant should not benefit from the plaintiff’s foresight in purchasing insurance or from the generosity of third parties.
Under § 490.715.1 RSMo, no evidence of collateral sources shall be admissible other than as provided in that section. The general rule bars collateral source evidence, but the statute creates specific exceptions for certain defendant-made payments and for evidence of the actual cost of medical care.
The Write-Off Problem Under § 490.715
The most contested collateral source issue in current Missouri practice involves medical billing write-offs. When a health insurer pays a medical bill, the provider typically accepts a contractually reduced amount and writes off the balance. The question is whether the plaintiff may recover the full billed amount, the amount actually paid, or some amount in between.
The governing rule is statutory. Under § 490.715.5 RSMo, parties may introduce evidence of the actual cost of the medical care or treatment rendered to the plaintiff. The phrase “actual cost” means the amount paid by or on behalf of the plaintiff, plus any remaining dollar amount necessary to satisfy the provider’s financial obligation after adjustment for contractual discounts, price reductions, or write-offs by any person or entity. § 490.715.5(2) RSMo.
A plaintiff may rebut the presumption that the reduced bill represents the value of medical treatment by presenting expert testimony that the full billed amounts were reasonable and that the plaintiff remained subject to liens for unpaid amounts. Klotz v. St. Anthony’s Medical Center, 311 S.W.3d 752 (Mo. 2010). The § 490.715 framework applies to past medical expenses; it does not restrict evidence of future medical charges that have yet to be incurred. Lowe v. Mercy Clinic East Communities, 592 S.W.3d 10 (Mo. Ct. App. 2019).
Medicaid is a collateral source that should not be disclosed to the jury. Lampe v. Taylor, 338 S.W.3d 350 (Mo. Ct. App. 2011). Advance or partial payments made by a defendant under § 490.710 are deducted from any final judgment by the court, outside the presence of the jury, and shall not be brought to the jury’s attention. Taylor v. Yellow Cab Co., 548 S.W.2d 528 (Mo. 1977).
A critical point confirmed by the Eastern District is that § 490.715, even as amended in 2017, does not limit medical bill evidence to the “actual cost” alone. In Brancati v. Bi-State Development Agency, 571 S.W.3d 625 (Mo. Ct. App. E.D. 2018), the court held that the amount charged for medical bills may be admitted into evidence under either the former or the amended version of the statute. The legislature’s use of “may” in § 490.715.5(1) makes clear that the actual cost of medical treatment is not the only admissible evidence of medical bills — the statute provides a vehicle for introducing actual cost evidence that would otherwise be excluded by the collateral source rule, but it does not mandate that billed charges are excluded. Nothing in the statute states the amount charged cannot be admitted. Both the amount billed and the amount paid or owed may be placed before the jury, leaving the jury to weigh both figures in determining the value of medical treatment rendered. Brancati, 571 S.W.3d at 635.
Practice Tip: Identify whether the plaintiff has outstanding provider liens before trial. If the provider has not released the plaintiff from any obligation to pay amounts written off, expert testimony that the billed amounts are reasonable — combined with evidence of the lien — provides the foundation to rebut the § 490.715 presumption and get the full billed amount before the jury.
V. The Eggshell Plaintiff Doctrine
One of the most practically important damage principles in Missouri personal injury practice is the eggshell plaintiff doctrine — the rule that a defendant takes the plaintiff as he finds him. A defendant is generally liable for the aggravation of pre-existing conditions caused by his negligence or a statutory violation. Miller v. Gulf, Mobile & Ohio R.R. Co., 386 S.W.2d 97, 102 (Mo. 1964). A jury is entitled to make that finding if there is substantial evidence of aggravation. Id.
The doctrine applies in its full force whether the pre-existing condition is minor or severe. In Dorsey v. Muilenburg, 345 S.W.2d 134 (Mo. 1961), the plaintiff had severe and long-standing bronchiectasis, emphysema, and myocardial degeneration. A relatively minor automobile collision aggravated those conditions and contributed to his death months later. The Missouri Supreme Court affirmed the wrongful death verdict, holding that the plaintiff was entitled to prove that the defendant’s negligence aggravated existing diseases and caused or brought about death at a time earlier than it otherwise would have occurred. Expert testimony that the accident “could and in fact did contribute to cause the death” of the plaintiff — based on the treating physician’s personal knowledge of conditions and changes in conditions — constituted substantial evidence of causation. Id. at 138-39.
The plaintiff in an eggshell case is not entitled to recover for conditions due entirely and wholly to a previous disease or injuries, but may recover for the aggravation of existing ailments caused by the defendant’s negligence — including such damages as proximately result from the activation of dormant disease. Kingman v. Dillard’s, Inc., 643 F.3d 607, 610 (8th Cir. 2011) (applying Missouri law). The line between an aggravation and the normal progress of a chronic pathological condition may be a hazy one, but under Missouri practice a jury is entitled to make the finding if there is substantial evidence of aggravation. Id.
Once the plaintiff satisfies the elements of her claim, the burden is on the defendant to challenge the extent to which the plaintiff’s injuries are directly attributable to the defendant’s negligence. The plaintiff need not with certainty or exactness prove the extent of damages — if neither party offers evidence on how to apportion damages between the pre-existing condition and the aggravation, it is the defendant, not the plaintiff, who has failed to meet the burden of proof on that issue. Kingman, 643 F.3d at 611.
Mortality tables are admissible in evidence even when the plaintiff had pre-existing diseases or was in poor health before the accident. The probative value of the tables may be weakened by evidence of ill-health, but such matters go to the weight of the evidence and not to its admissibility. Dorsey, 345 S.W.2d at 141.
Practice Tip: The defense will hammer pre-existing conditions in closing argument if you let them. Do not let them. Criswell v. Short, 70 S.W.3d 592 (Mo. Ct. App. 2002), reversed and remanded a defense verdict because the trial court allowed defense counsel to argue in closing that the defendant could not be responsible for a condition that existed before the accident, while simultaneously blocking plaintiff’s counsel from explaining the “take the plaintiff as you find them” rule. Under Missouri Supreme Court Rule 70.02 and MAI, attorneys may “flesh out” jury instructions in closing argument. Do not allow the rule to be misrepresented to the jury without objecting and demanding the right to correct it.
VI. Caps on Damages
General Personal Injury Cases — No Cap
Missouri does not impose a statutory cap on compensatory damages — economic or non-economic — in general personal injury negligence cases. The jury’s determination of damages is constitutionally protected. Under Mo. Const. art. I, § 22(a), the right of trial by jury as heretofore enjoyed shall remain inviolate. The Missouri Supreme Court has held that a legislative cap that operates wholly independently of the facts of the case eliminates the jury’s constitutionally protected function of determining the amount of damages. Watts ex rel. Watts v. Lester E. Cox Medical Centers, 376 S.W.3d 633 (Mo. 2012).
Medical Malpractice — § 538.210 RSMo
Medical malpractice cases against health care providers are subject to a statutory cap on non-economic damages under § 538.210 RSMo. The current cap structure is:
• Personal injury (non-catastrophic): No plaintiff shall recover more than $400,000 for non-economic damages, irrespective of the number of defendants. § 538.210.2(1).
• Catastrophic personal injury: No plaintiff shall recover more than $700,000 for non-economic damages. § 538.210.2(2).
• Death cases: No plaintiff shall recover more than $700,000 for non-economic damages. § 538.210.2(3).
These limits are subject to an annual adjustment of 1.7% effective January 1 of each year. § 538.210.10. The current values are published annually in the Missouri Register. The jury is not to be informed of the cap; no party or witness may inform the jury or potential jurors of the limitation. § 538.210.6.
The constitutionality of the § 538.210 cap has been litigated extensively. In Watts ex rel. Watts v. Lester E. Cox Medical Centers, 376 S.W.3d 633 (Mo. 2012), the Missouri Supreme Court held that the then-existing cap unconstitutionally infringed on the jury’s constitutionally protected purpose of determining the amount of damages, because such a limitation was not permitted at common law when Missouri’s constitution was first adopted in 1820. Following Watts, the legislature enacted a new version of § 538.210 effective August 28, 2015, with subsequent amendments in 2017 and 2020. The current version contains a self-executing invalidity provision under § 538.210.12: if a court declares any provision of the section unconstitutional, the entire section becomes invalid as of the date of that judgment and the prior version returns to force.
Critically, § 538.210.8 establishes a heightened punitive damages standard for health care providers: an award of punitive damages against a health care provider shall be made only upon a finding by the jury that the evidence clearly and convincingly demonstrated that the health care provider intentionally caused damage to the plaintiff or demonstrated malicious misconduct. Evidence of negligence — including indifference to or conscious disregard for the safety of others — shall not constitute intentional conduct or malicious misconduct for purposes of § 538.210 punitive damages. This standard is more demanding than the § 510.261 standard applicable to general tort defendants.
Government Defendants — § 537.610 RSMo
Claims against the state of Missouri and its political subdivisions are subject to the sovereign immunity cap under § 537.610 RSMo. Sovereign immunity is waived only to the extent of insurance coverage purchased by the governmental entity, with a maximum of $2,000,000 for all claims arising out of a single occurrence and $300,000 for any one person in a single accident or occurrence. § 537.610.1-2. These limits are subject to annual adjustment in accordance with the Implicit Price Deflator for Personal Consumption Expenditures. § 537.610.5. No award against a public entity within the scope of §§ 537.600-537.650 may include punitive or exemplary damages. § 537.610.3. These caps apply regardless of the number of defendants and regardless of the number of claims.
An important limitation on the cap: § 537.610.2 applies only to the sovereign entity itself and does not protect individual public employees. In Brancati v. Bi-State Development Agency, 571 S.W.3d 625 (Mo. Ct. App. E.D. 2018), the jury returned a $625,000 verdict against both Bi-State and its individual driver, jointly and severally. The trial court applied the inflation-adjusted cap of $414,418 to Bi-State but refused to cap the judgment against the driver. The Eastern District affirmed. The statutory cap under § 537.610.2 applies to “the state and its public entities” — it does not extend to individual public employees. The driver was not a public official performing a discretionary act and was therefore not protected by the cap that applied to his employer. The sovereign immunity statute’s damage limitation is not transferable to an individual employee of a governmental entity. Brancati, 571 S.W.3d at 637. This is a significant strategic consideration when the defendant is a public entity and its employee is also named — the employee faces uncapped personal liability while the entity’s exposure is limited.
VII. Punitive Damages
The Substantive Standard — § 510.261 RSMo
Punitive damages in Missouri general tort cases are governed by § 510.261 RSMo (effective August 28, 2020). Except as otherwise provided by statute, punitive damages shall not be awarded unless the claimant proves by clear and convincing evidence that the defendant (1) intentionally harmed the plaintiff without just cause or (2) acted with a deliberate and flagrant disregard for the safety of others. § 510.261.1.
Punitive damages may only be recovered if the trier of fact awards more than nominal damages, or if the claim invokes privacy rights, property rights, or rights protected by the United States or Missouri Constitution. § 510.261.2.
The amount of punitive damages shall not be based, in whole or in part, on harm to nonparties. § 510.261.6. Punitive damages can properly be awarded against an employer or other principal for an agent’s act only if: (1) the principal or a managerial agent authorized the doing and manner of the act; (2) the agent was unfit and the principal recklessly employed or retained him; (3) the agent was employed in a managerial capacity and was acting in the scope of employment; or (4) the principal or a managerial agent ratified or approved the act. § 510.261.3.
All common law limitations on punitive damages, and all limitations contained in other statutes, remain in full force and effect to the extent not expressly inconsistent with § 510.261. § 510.261.8; Reyna Hotel Corp. v. Lotus Hosp. Mgmt., LLC, 714 S.W.3d 423 (Mo. Ct. App. 2025).
Pleading Requirements
No initial pleading in a civil action may contain a claim for a punitive damage award. Any later pleading containing such a claim may be filed only with leave of court. § 510.261.5. A motion for leave must be filed no later than 120 days prior to the final pretrial conference (or 120 days before trial if no pretrial conference is scheduled), supported by affidavits, exhibits, or discovery materials establishing a reasonable basis for recovery of punitive damages. Id. The court must grant leave if it concludes that a trier of fact could reasonably conclude, based on clear and convincing evidence, that the standards for a punitive damage award have been met. Id.
Discovery of a defendant’s assets is available only after the trial court has granted leave to file a pleading seeking punitive damages under § 510.261.5. § 510.263.8 RSMo.
Bifurcated Trial Procedure — § 510.263 RSMo
All actions involving punitive damages shall be conducted in a bifurcated trial before the same jury if requested by any party. § 510.263.1.
In the first stage, the jury determines: (1) liability for compensatory damages; (2) the amount of compensatory damages, including nominal damages; and (3) whether the defendant is liable for punitive damages. Evidence of the defendant’s financial condition is not admissible in the first stage unless admissible for a proper purpose other than the amount of punitive damages. § 510.263.2.
If the jury finds punitive liability in the first stage, the second stage determines the amount of punitive damages. Evidence of the defendant’s net worth is admissible in the second stage. § 510.263.3. The doctrines of remittitur and additur, based on the trial judge’s assessment of the totality of the surrounding circumstances, apply to punitive damage awards. § 510.263.6.
A defendant may file a post-trial motion seeking a credit for punitive damages previously paid in any state or federal court arising out of the same conduct. § 510.263.4. The credit is disallowed if the defendant unreasonably continued the conduct after acquiring actual knowledge of its dangerous nature, or if the prior award arose under laws that substantially deviate from Missouri law on punitive damages. Id.
Practice Tip: In a general personal injury case with strong facts for punitive damages, consider whether bifurcation serves your client. Bifurcation lets the jury hear the full compensatory picture before the punitive phase — which can anchor a larger punitive award — but it also gives the defense a chance to regroup between stages. Evaluate the specific facts before deciding whether to request bifurcation or oppose the defendant’s request.
VIII. Jury Discretion and Remittitur
Missouri appellate review of a jury’s verdict on damages begins with the recognition that the jury retains virtually unfettered discretion in reaching its decision, because there is a large range between the damage extremes of inadequacy and excessiveness. An appellate court views the evidence in the light most favorable to the verdict and disregards evidence to the contrary. Stewart v. Partamian, 465 S.W.3d at 58.
There are two general types of excessive verdicts: (1) a verdict that is disproportionate to the evidence of injury and results from an honest mistake by the jury in assessing damages; and (2) a verdict that is excessive due to trial error that causes bias and prejudice by the jury. When a verdict is excessive because of an honest mistake, the excessive verdict can be remedied by ordering remittitur or granting a new trial. When an excessive verdict is caused by trial error generating bias and prejudice, a new trial is required. The amount of the verdict does not by itself establish bias or passion and prejudice — there must be some other error committed during trial. Stewart v. Partamian, 465 S.W.3d at 56-57.
Section 537.068 RSMo allows a court to reduce the damages awarded if, after reviewing the evidence in support of the jury’s verdict, the court finds that the verdict is excessive because the amount exceeds fair and reasonable compensation for the plaintiff’s injuries and damages. Id. at 57. Missouri Supreme Court Rule 78.10(b) refines the statutory remittitur procedure by requiring that, if a court sustains a motion for remittitur in whole or in part, the court’s order shall afford each party opposing such relief the option to file an election of a new trial. A court should not sustain a motion for remittitur or additur under § 537.068 without first determining that the verdict is against the weight of the evidence and that the moving party is entitled to a new trial. Stewart, 465 S.W.3d at 57-58. In medical negligence cases, § 538.300 RSMo prohibits courts from ordering remittitur.
Remittitur is not a basis for determining whether a verdict is excessive — it is a procedural option to remedy an excessive verdict once the standard for excessiveness has been independently established. Stewart, 465 S.W.3d at 57. If there is no error in the record except that the judgment is for a greater amount than the evidence will support, the appellate court will determine the amount of the excess and give the plaintiff the option of remitting the excess and having affirmance of the judgment for the remainder. Id.
IX. Conclusion
The Missouri damages framework rewards careful preparation and punishes improvisation. Economic damages require a complete evidentiary foundation — medical records, expert causation testimony, life care plans, economist reports, and proof of every category of loss. Non-economic damages require a compelling narrative of how the plaintiff’s life has changed, built through the plaintiff’s own testimony, the testimony of family and friends who knew the plaintiff before and after, and medical documentation of the injury’s lasting effects.
The eggshell plaintiff doctrine means that a plaintiff’s pre-existing conditions are not a weakness — they are part of the damages story. The defense will try to use those conditions to limit the verdict. Missouri law, correctly applied, prevents that. The collateral source rule and the § 490.715 framework mean that the battle over medical billing write-offs will be fought at every trial; knowing the statute and the cases that interpret it is essential to winning that battle.
Punitive damages under § 510.261 are available but procedurally demanding. The 120-day motion deadline, the clear and convincing evidence standard, and the bifurcated trial procedure require advance planning. In medical malpractice cases, the § 538.210 cap and the heightened intentional/malicious misconduct standard for punitive damages represent an entirely different framework that counsel must master before trial.
This post is intended as a reference framework, not a substitute for independent legal research. All statutes and cases cited should be verified against current Lexis authority before reliance in any specific proceeding.
