Estate Planning in Wyoming

Estate planning in Wyoming involves navigating a specific set of state laws that differ in important ways from neighboring states. Understanding these distinctions helps ensure your documents will be valid and your wishes carried out as intended.

Wyoming does not impose a state estate tax or inheritance tax, which means estates are only subject to the federal estate tax (currently exempting the first $15,000,00026 USC 2001(c), 2010; P.L. 119-21 §70106Verified Sep 15, 2026View source per person, or $30,000,00026 USC 2001(c), 2010; P.L. 119-21 §70106Verified Sep 15, 2026View source for married couples using portability).

Wyoming does not require a revocable living trust to be notarizedWyo. Stat. § 4-10-101 et seq.Verified Jul 15, 2026View source. Wyoming allows transfer-on-death deeds for real estate, enabling property to pass directly to named beneficiaries without probate. This is a significant probate avoidance tool that doesn't require creating a trust. Transferring a home into a revocable trust does not forfeit Wyoming's homestead exemption—the protection carries through to trust-held property. Transferring property into a revocable trust does not trigger a property tax reassessment in Wyoming, so property taxes remain at their current level. Wyoming fully enforces no-contest clauses in trusts and wills. A beneficiary who unsuccessfully challenges the document can lose their entire inheritance, which strongly discourages frivolous disputes.

Wyoming automatically revokes an ex-spouse as beneficiary on life insurance, retirement accounts, and similar designations upon divorce. However, these automatic revocations can be overridden by a divorce decree or by re-designating the ex-spouse after the divorce. Wyoming provides full creditor protection for inherited IRAs, meaning creditors cannot reach these funds—a protection not available in every state.

Wyoming fully authorizes remote online notarization (RON) for estate planning documents, including wills, trusts, healthcare directives, powers of attorney. RON covers the notarization step; whether the whole signing can happen remotely also depends on whether the document's witnesses may attend by video.
