Wyoming is the least populous state in the country. Fewer than 600,000 people across 97,914 square miles — roughly one person for every square quarter-mile. You’d think in a place that small, everyone would know everyone’s business. You’d think there wouldn’t be many secrets, including the secret of whether someone had a will.
And yet.
Wyoming is also the second-most popular state in the country for trust formation and LLC registration, behind only Delaware. Wealthy families across the country park assets in Wyoming entities to take advantage of the state’s extraordinary legal and tax environment: no state income tax, no estate tax, no inheritance tax, no corporate income tax. Asset protection trusts. Dynasty trusts that last forever. Privacy protections for LLC members that most states don’t offer.
This is the state’s actual legal infrastructure. It’s world-class. It’s sitting there, available to everyone who lives here.
And the average Wyomingite dies without a will.
Wyoming’s Intestate Succession Law
Wyoming’s intestacy statutes are found in Wyoming Statutes Title 2, Article 4. Wyoming does not follow the Uniform Probate Code — it uses a traditional intestacy framework, though the rules are generally straightforward.
Married with children:
- If all your children are also your spouse’s children: your spouse inherits your entire estate. Your children get nothing directly through intestacy from your estate.
- If you have children from a prior relationship: your spouse inherits 1/2 of your estate. Your children (from all relationships) split the other 1/2 equally.
Married with no children:
- Your spouse inherits everything.
Single with children:
- Your children inherit everything equally, per stirpes.
Single, no children, no spouse:
- Your parents inherit equally. If one parent is dead, the survivor takes everything.
- If both parents are dead: siblings split it. Half-siblings get equal shares with full siblings.
- Beyond siblings: grandparents, then their descendants.
- If truly no relatives: Wyoming escheats the estate.
The prior-relationship children issue:
Wyoming’s intestacy gives your spouse everything when all children are joint — which is a good result for a typical nuclear family. But the moment prior-relationship children enter the picture, the estate splits 50/50 between your spouse and your children. Your spouse may need to sell the family home to satisfy the children’s 50% claim in cash. This is the classic blended-family intestacy disaster, and Wyoming has no mechanism to prevent it.
The unmarried partner problem:
Wyoming does not recognize common law marriage. If you’ve been with your partner for 20 years and never married, they have zero intestate inheritance rights. Wyoming courts will not recognize the relationship for inheritance purposes. Your partner could be left with nothing while distant relatives you haven’t spoken to in decades inherit your estate.
What Probate Looks Like in Wyoming
Wyoming intestate estates go through district court — Wyoming’s trial courts of general jurisdiction, which also handle probate matters.
Timeline: 6-12 months for uncomplicated estates. Wyoming’s creditor claim period runs 3 months from the date of published notice, which sets a practical minimum on proceedings.
Costs: Attorney and personal representative fees in Wyoming are based on reasonableness. For probate estates, total fees typically run 2-4% of estate value. On a $400,000 estate, budget $8,000-$16,000 in fees.
Small estate procedures:
Wyoming has a streamlined process for small estates:
- Summary administration: Available when the estate’s gross value is $200,000 or less. This is a simplified process that avoids full formal probate administration.
- Affidavit procedure: For personal property only, with a threshold of $200,000 or less in personal property value. Heirs can collect personal assets using an affidavit.
- These $200,000 thresholds are among the most generous in the country — more Wyoming estates qualify for simplified administration than in most states.
Wyoming’s non-UPC approach:
Wyoming is one of the traditional intestacy states — it hasn’t adopted the Uniform Probate Code. This means probate is somewhat more court-supervised than in UPC states, but Wyoming’s generous small estate thresholds offset much of this for typical estates.
Wyoming-Specific Quirks
The tax haven reality:
Wyoming’s asset protection environment is genuinely remarkable:
- No state income tax
- No estate tax
- No inheritance tax
- No corporate income tax
- No franchise tax
- Perpetual dynasty trusts (no rule against perpetuities)
- Domestic asset protection trusts — you can be a beneficiary of a trust that protects your assets from creditors
- Among the strongest LLC member privacy laws in the country (members not listed in public records)
These aren’t minor advantages. Wealthy families and financial advisors actively seek out Wyoming for estate planning structures that simply aren’t available or as favorable elsewhere. The state has built a legal infrastructure for sophisticated wealth management.
But using these tools requires one thing: you have to actually use them. A dynasty trust doesn’t exist until you create it. An asset protection trust doesn’t protect anything until it’s funded. And a will — the absolute baseline — doesn’t exist until you write one.
The Ranch:
Wyoming has significant ranch and agricultural land. Family ranches represent both significant financial value and deep family heritage. Under intestacy with prior-relationship children, a ranch can fracture into fractional co-ownership between a surviving spouse and children from a first marriage — people who may have very different ideas about whether the ranch should be sold or maintained. A will (or a more sophisticated succession plan using a trust or LLC) is the only way to keep a working ranch intact.
Mineral rights and energy:
Wyoming is a major energy-producing state — coal, natural gas, oil, and wind power. Mineral rights are significant estate assets. Like West Virginia, Wyoming has widespread separation of surface and subsurface ownership. Dying without a will creates the same mineral rights fragmentation problem: multiple heirs owning fractional interests in mineral leases, unable to collectively negotiate with energy companies.
No common law marriage:
Wyoming does not recognize common law marriage. If you’re not formally married, you’re not married for inheritance purposes. Full stop.
Privacy-focused LLC laws:
Wyoming LLC members are not required to be disclosed in public records — a key reason businesses incorporate here. If you own Wyoming LLC interests, those interests pass through intestacy like any other asset, but heirs may need legal assistance identifying and valuing them, since public records won’t reveal membership.

Frequently Asked Questions
Q: Does Wyoming have any estate or inheritance tax?
A: No. Wyoming has no state estate tax, no state inheritance tax, no state income tax, and no corporate income tax. Your heirs inherit everything you leave them without owing Wyoming anything. Federal estate tax (exemption: $13.6 million in 2026) is the only potential tax concern, and most Wyoming residents won’t reach the federal threshold.
Q: My partner and I have lived together for 15 years but never married. Does Wyoming recognize that as a common law marriage?
A: No. Wyoming does not recognize common law marriage. Your 15-year partner has zero intestate inheritance rights regardless of how long you’ve been together, how intertwined your finances are, or how clearly you intended them to be your heir. A will is the only way to ensure your partner inherits anything.
Q: What is Wyoming’s small estate threshold?
A: Wyoming is generous: $200,000 for both the summary administration process and the affidavit procedure for personal property. This means a larger percentage of Wyoming estates qualify for simplified administration compared to most states. However, real estate typically still requires formal proceedings to clear title.
Q: Why do wealthy families use Wyoming LLCs and trusts if they don’t live there?
A: Wyoming’s legal infrastructure — perpetual dynasty trusts, domestic asset protection trusts, LLC privacy, no state taxes — is available to anyone willing to form a Wyoming entity or trust, regardless of where they live. Families form Wyoming entities specifically to hold assets, protect them from creditors, and pass them across generations with minimal tax and maximum control. You don’t need to live in Wyoming to use Wyoming law; you just need to establish a proper legal structure there.
Q: How does Wyoming intestacy handle my ranch if I have kids from a first marriage and a current spouse?
A: Your current spouse gets 50% of your estate; your children (including those from your first marriage) split the other 50%. If the ranch is the primary estate asset, your spouse and children from your prior marriage now jointly own it — and must agree on management, maintenance, and whether to sell. This outcome destroys working ranches. A will — ideally combined with a trust or LLC structure for succession — is the only way to keep the ranch intact and in the right hands.
