Wyoming Statute of Limitations (WY)
Wyoming has a long 10-year SOL for written contracts, 8 years for oral contracts, 4 years for personal injury and property damage, and 2 years for medical malpractice. Wyoming applies the discovery rule, which means the statute of limitations clock may not start until the plaintiff discovers or should have discovered the cause of action.

Discovery Rule in Wyoming
Wyoming applies the discovery rule. Under this doctrine, the statute of limitations does not begin to run until the plaintiff discovers or reasonably should have discovered the cause of action. This is particularly important for medical malpractice, fraud, and latent injury claims where the harm may not be immediately apparent. However, most states also impose an outer "statute of repose" that sets an absolute deadline regardless of when discovery occurs.
Tolling Provisions
Tolling provisions pause or extend the statute of limitations under certain circumstances. In Wyoming:
Tolled for defendant's absence from state. Minors have until age 18 plus the applicable period.
Key Considerations for Wyoming
- Written vs. oral contracts: Wyoming allows 10 years for written contracts and 8 years for oral contracts. The 2-year difference reflects the stronger evidence provided by written agreements.
- Personal injury urgency: At 4 years, Wyoming's personal injury SOL is moderate compared to other states (national average: 2.7 years). This provides a reasonable window to investigate and file a claim.
- Debt collection: Creditors have 10 years to sue for unpaid debts in Wyoming. After this period, the debt becomes "time-barred" and cannot be collected through the courts (though it may still appear on credit reports).
- Medical malpractice: Wyoming allows 2 years for medical malpractice claims. The discovery rule applies, which can extend this period if the injury was not immediately apparent.
