Wyoming estate planning is unusually simple by national standards. The state has no income tax, no estate tax, and no inheritance tax — eliminating most of the tax- planning complexity that drives planning in higher-tax states. Wyoming’s focus is on the four documents, probate avoidance, and Medicaid coordination.
The four documents to have in place this year
These are universally applicable in Wyoming regardless of wealth. Most cost between $250 and $1,000 through a Wyoming-licensed attorney; a trust adds another $1,000–$3,000.
1. Durable Power of Attorney (W.S. §3-9-101 et seq.)
Wyoming has adopted aspects of the Uniform Power of Attorney Act through W.S. §3-9-101 et seq. The statute provides for durable POAs, addresses agent authority and accountability, and provides default protections for third parties acting in reliance on a properly executed document.1
A WY DPOA names an agent (attorney-in-fact) to handle your parent’s financial affairs if they become unable to. Key Wyoming-specific points:
- The document must be notarized.
- To be durable (survive incapacity), the document must contain explicit durability language.
- Hot powers (gifting, beneficiary changes, creating or amending trusts) typically need to be specifically granted; general grants of authority may not carry them.
- Out-of-state POAs are generally honored if validly executed where signed, but WY financial institutions vary in practical acceptance.
2. Health Care Power of Attorney (W.S. §35-22-401 et seq.)
Wyoming’s Health Care Decisions Act (W.S. §35-22- 401 et seq.) governs medical decision-making documents. The Health Care POA names a representative (agent) to make medical decisions when your parent cannot communicate their wishes. Two adult witnesses or notarization required.2
3. Advance Health Care Directive (Living Will)
The Advance Health Care Directive under the same Act expresses your parent’s wishes about end-of-life care — specifically whether to withhold or withdraw life-sustaining treatment in defined terminal or persistent-vegetative-state conditions. Often combined with the Health Care POA into a single document.
4. Revocable Living Trust
A revocable trust is the most flexible probate-avoidance tool. Your parent transfers assets into the trust during life, retains full control as trustee, and names a successor trustee to manage and distribute assets at death without probate. Wyoming has modern trust law provisions and is generally trust-friendly.
No state estate tax, no state inheritance tax, no income tax
Wyoming has no state estate tax, no inheritance tax, and no state income tax. The federal estate tax (~$13.99M per individual in 2025; subsequent federal legislation has extended portions of the 2017 TCJA) is the only estate- tax concern for Wyoming families — effectively a non-issue for typical asset levels.3
That makes WY estate planning unusually focused on non-tax considerations: who manages assets if your parent becomes incapacitated, who inherits, how to avoid probate if appropriate, and how to preserve Medicaid LTC eligibility if needed.
Probate in Wyoming
Wyoming probate is governed by the WY Probate Code (W.S. Title 2) and administered through the District Court in each of WY’s 23 counties. The process typically runs 6–12 months for uncontested estates. Probate-fee structure is modest by national standards — no statutory percentage fee like Florida; attorney fees are typically billed hourly or by flat fee.4
Probate-avoidance toolkit:
- Small estate affidavit for estates with personal property under ~$200,000 (W.S. §2-1-201). Faster and significantly less expensive than full probate.
- Transfer-on-Death (TOD) deeds for real property (W.S. §2-18-101 et seq.). Converting a deed to TOD eliminates probate for the home.
- Payable-on-Death and TOD accounts for financial assets.
- Beneficiary designations on retirement accounts, life insurance, annuities.
- Joint tenancy with survivorship for appropriate assets.
- Revocable Living Trust for comprehensive probate avoidance, particularly for unmarried individuals or families with multi-state property.
Mineral rights and ranch land in WY estates
Wyoming estate planning has features many states don’t: the prominence of mineral rights (oil, gas, coal, uranium) and ranch land. Both create planning considerations:
- Mineral rights as Medicaid-countable assets. Royalty interests are countable assets for Medicaid LTC eligibility. Failure to disclose can result in denial or repayment. See our Wyoming Medicaid guide.
- Heirs’ property risks.Ranch land held jointly across generations without clear chain of title is common in WY. Without active planning, the property becomes “heirs’ property,” which can result in forced partition or sale.
- Federal grazing leases. BLM and Forest Service grazing allotments are common WY assets that require explicit succession planning.
If your parent moved to Wyoming from another state
Out-of-state wills are generally valid in WY if validly executed under the law of the state where signed. But they often miss WY-specific opportunities — particularly the unusually low-tax environment that changes the planning equation. A WY elder-law attorney can review an existing plan for ~$200–$400 — modest cost relative to planning advantages a WY-aware refresh can unlock.
Guardianship and conservatorship
If incapacity occurs without documents in place, WY Guardianship and Conservatorship proceedings (W.S. §3-2-201 et seq.) provide the legal framework. The process is typically $2,000–$5,000 in legal fees plus ongoing administrative costs. The whole point of the four-document package is to avoid this by establishing decision-makers in advance.5
What to do this quarter
- Locate (or create) your parent’s four documents: DPOA, Health Care POA, Advance Directive, and (if appropriate) Revocable Living Trust.
- Confirm TOD designations on accounts, retirement accounts, and (if applicable) real property deeds.
- Document mineral rights, grazing allotments, and ranch land titles explicitly.
- For families with multi-county or multi-state property, consider a revocable trust to consolidate administration.
- If your parent moved to WY from another state, get a plan review.
