The rules in Oklahoma

Filing deadline

2 years

Counted from when the injury was discovered. File within 2 years from when you knew or reasonably should have known of the injury.

Okla. Stat. tit. 76, § 18

Discovery rule

Applies

Yes.

Outer limit

None found

We found no statute of repose for Oklahoma.

Damage caps

For injuries on or after September 1, 2025: $500,000 in bodily injury cases, with no limit for permanent and severe physical injury, $1,000,000 for a permanent mental injury that severely impairs work or daily life, and no limit for reckless, grossly negligent, fraudulent, intentional or malicious conduct.

Oklahoma reinstated a general non-economic cap in 2025 (SB 453) after the old $350,000 cap was struck down in Beason v. I.E. Miller Services (2019). It applies to medical malpractice as a bodily injury action.

Okla. Stat. tit. 23, § 61.3 (SB 453, 2025)

Children

Different clock

Special time limits apply to minors under title 76, § 18; confirm the exact deadline for a child's claim with a lawyer.

Affidavit of merit

Not required

No longer required: the Oklahoma Supreme Court struck down the affidavit of merit statute in John v. Saint Francis Hospital (2017).

Notice before suing

Not required

No pre-suit notice requirement.

Shared fault

Modified comparative (51% bar)

Modified comparative fault: barred above 50% of the fault

Experts

Expert evidence

Expert qualification rules are set out in Okla. Stat. tit. 63, § 1-1708.1I.

Whether the new caps survive a constitutional challenge, as earlier caps did not, is an open question.
