SB 1180 - This act modifies provisions of law relating to civil procedure.

COLLATERAL SOURCE (SECTION 490.715)
This act modifies the rule for determining the admissibility of evidence of collateral source payments in civil cases. Currently, parties may introduce evidence of the actual cost of the medical care or treatment rendered to a plaintiff or a patient whose care is at issue. Additionally, this act modifies this provision by providing that in any action where a plaintiff seeks to recover for personal injury, bodily injury, or death, any party may introduce evidence of the actual cost of the medical care or treatment rendered to a plaintiff or to the person whose injury or death the recovery is sought.

No party shall introduce evidence of the amount billed for medical care or treatment rendered to a plaintiff or a patient at issue in the case if the amount billed has been discounted pursuant to any contract, price reduction, write-off, or payment less than the amount billed for the medical care or treatment. The actual cost of medical care or treatment rendered to a plaintiff or a patient and any discounts pursuant to a contract, price reduction or write-off shall be admissible as relevant to the potential cost of future treatment.

This provision is identical to a provision in SB 268 (2025) and in SB 314 (2025), is substantially similar to HB 273 (2023), SB 975 (2022), HB 1715 (2022), a provision in HCS/SCS/SB 119 (2021), and in the perfected HCS/HB 922 (2021), and is similar to HB 1646 (2026), HB 2405 (2026), HB 69 (2025), HB 965 (2024), HB 147 (2021), HCS/HB 577 (2021), HB 121 (2019), and HB 1407 (2018).

INTERSTATE DEPOSITION AND DISCOVERY ACT (SECTIONS 510.500 TO 510.521)
This act establishes the Uniform Interstate Depositions and Discovery Act, which provides procedures for out-of-state subpoenas for certain forms of discovery conducted in Missouri.

To request a subpoena in Missouri, a party shall submit a foreign subpoena to a clerk of the court in the county in which discovery is sought to be conducted. The clerk shall promptly issue a subpoena, which shall incorporate the terms used in the foreign subpoena and include contact information of the attorneys and any party not represented by an attorney in the proceeding to which the subpoena relates. A request for issuance of a subpoena pursuant to this act shall not constitute an appearance in Missouri courts.

The Missouri Supreme Court Rules of Civil Procedure and the laws of this state apply to subpoenas issued pursuant to this act and such subpoenas shall be served in compliance with such rules and laws. Additionally, an application for a protective order or to enforce, quash, or modify a subpoena issued by clerk of this state shall comply with such court rules and laws of this state. However, in applying and construing this act, consideration shall be given to the need to promote uniformity among the states.

These provisions shall apply to requests for discovery in cases pending on August 28, 2026.

These provisions are identical to provisions in HCS/SB 1067 (2026), SB 1386 (2026), HB 1711 (2026), in HCS/HB 3116 (2026), in HCS/HB 83 (2025), HB 128 (2025), in SCS/HCS/HB 176 (2025), in HCS/SS/SB 221 (2025), in SB 352 (2025), SCS/SB 897 (2024), in SCS/HCS/HB 2064 & HCS#2/HB 1886 (2024), SB 394 (2023), and SB 1005 (2022) and are substantially similar to provisions in HB 1452 (2024), in CCS/HCS/SS/SCS/SB 72 (2023), HB 84 (2023), in SCS/HCS/HBs 994, 52 & 984 (2023), HB 1549 (2022), HB 347 (2021), and HB 2570 (2020).

DETERMINATION OF FAULT OF PARTIES AND NONPARTIES IN CIVIL ACTIONS (SECTIONS 537.059, 537.060 & 537.067)
This act provides that in all tort actions in which any party contends that damages were caused by the alleged fault of more than one person or entity, the trier of fact shall determine the amount of fault attributable to each person or entity, regardless of whether the person or entity is a party to the action and regardless of whether the person or entity has settled or been released from liability. Fault of another person or entity may be alleged by any party in the action in any claim, counterclaim, cross-claim, or as an affirmative defense. Any determination of fault attributable to a person or entity not a party to the action shall not be binding against or otherwise affect the rights or liabilities of the person or entity.

Currently, when an agreement by release, covenant not to sue, or a covenant not to enforce a judgment is given in good faith to one of two or more persons liable in tort for the same injury or wrongful death, the claim for damages shall be reduced by the greater of either the stipulated amount of the agreement or the amount of consideration paid. Further, the agreement shall discharge the tort-feasor to whom it is given from all liability for contribution or noncontractual indemnity, as defined, to any other tort-feasor. This act repeals this provision and provides that in all tort-actions for damages, if the defendant is found to bear 51% or more of the fault, then the defendant shall be jointly and severally liable for the amount of the judgment less the total of any stipulated amount in any release or covenant with any other person or entity alleged to have been at fault or any amount of consideration paid by such person or entity, whichever is greater.

These provisions are identical to provisions in SB 314 (2025), SB 1463 (2024), SB 467 (2023), in SB 708 (2023), and in SB 669 (2022) and are similar to provisions in SB 1243 (2022).

REFERENCES OF DAMAGES TO JURIES (SECTION 537.092)
This act provides that neither party nor the attorneys of the parties in any civil action in which the trier of fact is a jury shall seek or make reference to a specific dollar amount or state a range for the jury to consider with respect to awards for noneconomic damages.

This provision is identical to a provision in SB 268 (2025), in SB 314 (2025), and SB 987 (2024) and is substantially similar to HB 2017 (2022) and HCS/HB 148 (2021).

DISCLOSURE REQUIREMENTS IN CIVIL ACTIONS FOR LATENT INJURIES (SECTION 537.870)
This act provides that within 30 days of filing a civil action involving a latent injury or disease or a claim for medical monitoring, the claimant shall file a sworn information form specifying the evidence that provides the basis for each claim against each defendant and shall include certain disclosures detailed in the act. The claimant shall supplement the information when the claimant receives information required to be disclosed or when the claimant becomes aware that a prior disclosure was inaccurate or incomplete. Discovery shall not commence against a defendant until the defendant's product, substance, or premises is specifically identified in the disclosures. The court, on motion by a defendant, shall dismiss the action without prejudice for any defendant that was not specifically identified in the disclosures or when a claimant fails to comply with the requirements of this provision.

This provision is identical to a provision in SB 268 (2025) and in SB 314 (2025) and is similar to a provision in SB 708 (2023).

clerk of court in the county in which discovery is sought to 3
be conducted in this state. A request for the issuance of a 4

(2) Contain or be accompanied by the names, addresses, 15

Missouri supreme court rules of civil procedure and laws of 3
this state. 4
510.512. The Missouri supreme court rules of civil 1

537.059. In all actions in which there is any count 1
alleging a tort to recover damages and in which any party 2
contends that the damages were caused by the alleged fault 3
of more than one person or entity, the trier of fact shall 4
determine the amount of fault attributable to each person or 5
entity, regardless of whether the person or entity is a 6
party to the action, and regardless of whether the person or 7
entity has settled or been released from liability. Fault 8
of another person or entity may be alleged by any party to 9
the tort action in any claim, counterclaim, cross-claim, or 10
as an affirmative defense. Any determination by the trier 11
of fact as to the amount of fault attributable to a person 12
or entity not a party to the action at the time of trial 13
shall not be binding against or otherwise affect the rights 14
or liabilities of that person or entity. 15
537.060. Defendants in a judgment founded on an action 1
for the redress of a private wrong shall be subject to 2
contribution, and all other consequences of such judgment, 3
in the same manner and to the same extent as defendants in a 4
judgment in an action founded on contract. When an 5
agreement by release, covenant not to sue or not to enforce 6
a judgment is given in good faith to one of two or more 7
persons liable in tort for the same injury or wrongful 8
SB 1180 6
death, such agreement shall not discharge any of the other 9
tort-feasors for the damage unless the terms of the 10
agreement so provide[; however such agreement shall reduce 11
the claim by the stipulated amount of the agreement, or in 12
the amount of consideration paid, whichever is greater. The 13
agreement shall discharge the tort-feasor to whom it is 14
given from all liability for contribution or noncontractual 15
indemnity to any other tort-feasor. The term 16
"noncontractual indemnity" as used in this section refers to 17
indemnity between joint tort-feasors culpably negligent, 18
having no legal relationship to each other and does not 19
include indemnity which comes about by reason of contract, 20
or by reason of vicarious liability]. 21
537.067. 1. In all tort actions for damages, if a 1
defendant is found to bear fifty-one percent or more of 2
fault, then such defendant shall be jointly and severally 3
liable for the amount of the judgment rendered against the 4
defendants less the total of any stipulated amount in any 5
release, covenant not to sue or not to enforce a judgment 6
under any agreement with any other person or entity alleged 7
to have been at fault pursuant to section 537.059, or any 8
consideration paid by such person or entity, whichever is 9
greater. If a defendant is found to bear less than fifty- 10
one percent of fault, then the defendant shall only be 11
responsible for the percentage of the judgment for which the 12
defendant is determined to be responsible by the trier of 13
fact; except that, a party is responsible for the fault of 14
another defendant or for payment of the proportionate share 15
of another defendant if any of the following applies: 16
(1) The other defendant was acting as an employee of 17
the party; 18
SB 1180 7
(2) The party's liability for the fault of another 19
person arises out of a duty created by the federal 20
Employers' Liability Act, 45 U.S.C. Section 51. 21
2. The defendants shall only be severally liable for 22
the percentage of punitive damages for which fault is 23
attributed to such defendant by the trier of fact. 24
3. In all tort actions, no party may disclose to the 25
trier of fact the impact of this section. 26
537.092. Notwithstanding any provision of law to the 1
contrary, in any civil action in which the trier of fact is 2
a jury, neither a party nor the attorneys of a party shall 3
seek or make reference to a specific dollar amount or state 4
a range for the jury to consider with respect to awards for 5
noneconomic damages, as that term is defined in section 6
538.205. 7
537.870. 1. Within thirty days of filing a civil 1
action involving a latent injury or disease or a claim for 2
medical monitoring, the claimant shall file a sworn 3
information form specifying the evidence that provides the 4
basis for each claim against each defendant. The sworn 5
information form shall include the following with 6
specificity: 7
(1) The claimant's name, date of birth, marital 8
status, occupation, smoking history, current and past 9
residences, current and past worksites, current and past 10
employers, and if applicable, the name of any individual 11
through whom the claimant alleges exposure to the product or 12
substance that forms a basis for the civil action; 13
(2) The name and address of each individual who is 14
knowledgeable about the exposures or events that form a 15
basis for the civil action and the individual's relationship 16
to the claimant; 17
SB 1180 8
(3) The manufacturer or seller and specific brand and 18
trade name of each product or substance that forms a basis 19
for the civil action; 20
(4) Each site, including the address of each site, and 21
the specific location at each site where any exposure or 22
event occurred that form a basis for the civil action; 23
(5) The beginning and ending dates of each exposure or 24
event that form a basis for the civil action and the 25
specific manner, frequency, and duration of each exposure or 26
event that form a basis for the civil action; 27
(6) The specific disease or injury that is alleged; and 28
(7) A certification that all supporting documentation 29
relating to the information required by this section has 30
been provided to the parties. 31
2. A claimant shall supplement the information 32
required by this section when the claimant receives 33
information that is required to be disclosed or becomes 34
aware that a prior disclosure was inaccurate or incomplete. 35
3. Discovery shall not commence against a defendant 36
until the defendant's product, substance, or premises is 37
specifically identified in the disclosures required by this 38
section. 39
4. The court, on motion by a defendant, shall dismiss 40
the civil action without prejudice as to any defendant whose 41
product, substance, or premises is not specifically 42
identified in the disclosures required by this section. 43
5. The court, on motion by a defendant, shall dismiss 44
the civil action without prejudice as to the moving 45
defendant or as to all defendants, as applicable, if the 46
claimant fails to comply in whole or in part with the 47
provisions of this section. 48
