Prenuptial Agreement Cost in Wyoming
Last updated 5 min read
A prenuptial agreement in Wyoming typically costs $1,000 – $2,500 for a simple agreement and up to $5,000 – $10,000 for complex estates. Wyoming prenup costs depend on attorney rates, how complex your finances are, and whether both spouses retain their own lawyer. This page isn't legal advice — it's a plain-English summary of how a prenup in Wyoming works, what it costs, and what the state requires.
Cost breakdown
| Complexity | Typical cost | Who this fits |
|---|---|---|
| Simple | $1,000 – $2,500 | W-2 income, no business, no kids from prior relationships |
| Moderate | $2,500 – $5,000 | Real estate, retirement accounts, modest separate property |
| Complex | $5,000 – $10,000 | Business interests, multi-state property, expected inheritance |
Average attorney rate in Wyoming: $200–$400/hr. Both spouses hiring separate attorneys typically adds 50–75% to the total bill.
What Wyoming law requires
- In writing: Yes — required.
- Notarization: Not required, but recommended for evidentiary purposes.
- Independent counsel: Strongly recommended (and often outcome-determinative if litigated).
- Community property state: No — equitable distribution applies in the absence of an agreement.
The controlling statute is Wyoming common law (Laird v. Laird, 597 P.2d 463) — read the full text on the Wyoming legislature site.
Wyoming has not adopted the UPAA — prenups are governed entirely by common law. Under Laird v. Laird, they are analyzed using standard contract rules: written, signed voluntarily, with full disclosure of assets and debts. Courts refuse enforcement of agreements signed under duress or unconscionable at execution. Independent counsel is not strictly required but heavily recommended.
A notable Wyoming case
Laird v. Laird, 597 P.2d 463 (Wyo. 1979). Wyoming Supreme Court established that prenups are enforceable as contracts and construed under standard contract rules. Upheld the agreement where the challenging spouse had opportunity to read it and showed no pressure or deceit. Remains the foundational Wyoming prenup case.
