Can a Minor Draft a Valid Last Will in Wyoming?

When a teenager in Cheyenne, Casper, or Sheridan accumulates substantial savings from ranching, inherits family mineral royalties, or receives a personal injury settlement, parents and young earners often ask whether a minor can sign a Last Will and Testament to protect those assets. Unlike general personal property ownership-where a Wyoming youth can earn wages or hold title to a vehicle-the legal power to direct where property goes after death is strictly gatekept by the Wyoming Probate Code.

In Wyoming, executing a Last Will and Testament requires full testamentary capacity. If an underage resident writes out inheritance instructions and passes away before reaching adulthood, the local probate court will declare the document legally void, triggering state intestacy laws that may distribute the youth's property in ways the family never anticipated.

The 18-Year-Old Age Requirement for Testamentary Capacity in Wyoming

The foundational rule governing who may execute a Will in the Cowboy State is codified in Wyo. Stat. § 2-6-101, which states that any person of legal age and sound mind may make a Will. To determine what constitutes legal age, Wyoming probate courts look directly to Wyo. Stat. § 14-1-101, which establishes 18 years of age as the statutory age of majority across the state.

For adult testators, Wyoming courts evaluate mental competency-whether the person understands the nature of the act, the extent of their property, and the natural objects of their bounty-on a case-by-case basis, as illustrated in Matter of Estate of Brosius, 683 P.2d 663 (WY Supreme Court 1984). For minors, however, the age threshold of 18 is an irrebuttable statutory barrier. Even if a 16-year-old or 17-year-old is exceptionally mature and follows every formal execution requirement-such as signing in front of two competent witnesses under Wyo. Stat. § 2-6-112 or writing a completely handwritten holographic Will under Wyo. Stat. § 2-6-113-the instrument has zero legal force if signed prior to the testator's 18th birthday.

Legal Capacity for Emancipated Teens and Underage Military Personnel

Many families assume that if a teenager is legally emancipated, married, or serving in the armed forces, they automatically gain the right to draft a Will in Wyoming. A careful reading of Title 14 of the Wyoming Statutes reveals a critical legal distinction between general emancipation and testamentary capacity.

Under Wyo. Stat. § 14-1-201, emancipation in Wyoming can occur in three ways: through legal marriage, through active military service of the United States, or by obtaining a formal Declaration of Emancipation from a District Court judge at age 17 or older pursuant to Wyo. Stat. § 14-1-203. However, when a 17-year-old obtains a court decree of emancipation, Wyo. Stat. § 14-1-202 explicitly restricts the legal effect of that decree. The statute states that an emancipation decree only recognizes the minor as an adult for five specific purposes:

• Entering into a binding contract (such as signing an apartment lease or financing a vehicle);
• Suing and being sued in civil court in their own name;
• Buying or selling real property during their lifetime;
• Establishing an independent legal residence; and
• Being held accountable under the adult criminal laws of the state of Wyoming.

Because Wyo. Stat. § 14-1-202 uses the restrictive phrase 'shall only' and omits the right to execute a Will under Wyo. Stat. § 2-6-101, a court-emancipated 17-year-old can buy and sell land in Wyoming during life and even record a lifetime contractual transfer, but still faces challenges if relying on a traditional probate Will before turning 18. Similarly, while 17-year-olds who enlist in the U.S. Armed Forces with parental consent under 10 U.S.C. § 505 are recognized as emancipated for healthcare and contract purposes under Wyo. Stat. § 14-1-101, their primary estate planning protection comes from federal law. Specifically, under 38 U.S.C. § 1970, underage military personnel have full federal statutory authority to designate beneficiaries for Servicemembers' Group Life Insurance (SGLI) and military death gratuities, which bypass Wyoming probate courts entirely.

What Happens to a Minor's Assets Without a Will in Wyoming?

Because an unemancipated minor cannot execute a valid Will, any probate assets owned solely by a deceased minor are distributed according to Wyoming's laws of intestate succession under Wyo. Stat. § 2-4-101. Many parents in Wyoming are surprised to learn that the state's intestacy formula does not give 100% of a deceased child's estate solely to the parents.

Under Wyo. Stat. § 2-4-101, if a minor dies unmarried and without children, their net probate estate passes to their father, mother, brothers, and sisters in equal parts. For example, if a 16-year-old in Gillette passes away with $100,000 in a settlement account and is survived by two parents and two younger siblings, each parent and each sibling receives an equal 25% ($25,000) share. Because the surviving younger siblings are also minors, their inherited shares cannot be handed to them directly and may require court-supervised conservatorships unless the estate qualifies for simplified distribution.

If the minor's total Wyoming probate estate (less liens and encumbrances) is valued at $400,000 or less, the family can avoid full formal administration after a 30-day waiting period by using a Small Estate Affidavit for personal property under Wyo. Stat. § 2-1-201 or an Application for a Decree of Summary Distribution for real property and mineral rights under Wyo. Stat. § 2-1-205.

Step-by-Step Process in Wyoming to Protect a Minor's Assets and Plan Ahead

Whether your family lives in Cheyenne, Casper, Laramie, Gillette, or Jackson, you can use lawful non-probate tools to structure and protect a young person's property before they turn 18.

Step 1: Establish Custodial Accounts Under the Wyoming UTMA

Instead of placing large sums of money, stocks, or royalties directly into a minor's individual name, parents and donors typically transfer assets to a custodian under the Wyoming Uniform Transfers to Minors Act pursuant to Wyo. Stat. § 34-13-114. The custodian manages and invests the funds for the minor's benefit until the youth reaches age 21 (the statutory termination age for UTMA gifts under Wyo. Stat. § 34-13-133), or age 18 for non-gift custodial transfers.

Step 2: Utilize Non-Probate Beneficiary Designations and Life Insurance

Wyoming law provides specific statutory exceptions that allow teenagers to designate beneficiaries outside of a Will. Under Wyo. Stat. § 26-15-105, any minor who is 15 years of age or older has the legal capacity to contract for life or disability insurance on their own life and name their father, mother, spouse, child, brother, or sister as the beneficiary. Additionally, bank accounts structured with Payable-on-Death (POD) designations or assets held in a parent-created revocable trust bypass intestate succession entirely.

Step 3: Petition for Conservatorship or Emancipation in District Court (If Needed)

If a minor receives an inheritance or personal injury award exceeding simple custodial limits, a parent must petition for appointment as a conservator under Wyo. Stat. § 3-3-101. Conversely, if a self-supporting 17-year-old living separately with parental consent seeks adult contract rights under Wyo. Stat. § 14-1-203, they file a verified emancipation application in their local District Court, such as the Laramie County District Court, Cheyenne, the Natrona County District Court, Casper, or the Albany County District Court, Laramie. Once granted, the teen can record the decree and obtain an emancipated designation on their identification card through the Wyoming Department of Transportation, Cheyenne under Wyo. Stat. § 14-1-205.

Step 4: Execute a Valid Wyoming Will Immediately Upon Turning 18

On the day a young adult turns 18, they acquire full testamentary capacity under Wyo. Stat. § 2-6-101. At that point, they should execute a formal written Will signed before two witnesses under Wyo. Stat. § 2-6-112 and attach a notarized self-proving affidavit under Wyo. Stat. § 2-6-114 so the Will can later be admitted to probate without requiring live witness testimony. If a minor passes away before age 18 and leaves an estate under $400,000, the family can claim personal property using Form PPP 02, Wyoming, Judicial Branch, Intestate Affidavit for Distribution of Personal Property or real estate using Form PRP 02, Wyoming, Judicial Branch, Intestate Application for Distribution of Real Property.

How Much Does Estate & Guardianship Planning Cost in Wyoming?

Planning for a minor's assets or handling an underage estate in Wyoming involves predictable court fees and legal expenses:

• District Court Probate & Conservatorship Filing Fee: $160.00 total across all Wyoming counties (consisting of a $110 base filing fee, a $40 judicial systems automation fee, and a $10 indigent civil legal services fee pursuant to Wyo. Stat. § 2-2-401 and Wyo. Stat. § 5-3-206).
• Court Inventory Fee: Under Wyo. Stat. § 2-2-401, estates or conservatorships valued at $5,000 to $10,000 pay an additional $5.00, plus $5.00 for each additional $10,000 of appraised value.
• County Clerk Small Estate Affidavit Recording Fee: Typically $12.00 for the first page and $3.00 for each additional page under Wyo. Stat. § 18-3-402.
• Wyoming Estate Planning Lawyer Fees: Drafting a young adult Will package at age 18 generally costs between $300 and $800, while setting up a minor's trust or handling an uncontested conservatorship petition typically ranges from $1,500 to $3,500 (with average Wyoming probate attorney hourly rates ranging from $250 to $350 per hour).

How Long Does the Process Take?

Timelines in Wyoming depend on which legal mechanism your family uses:

• Drafting a Trust or UTMA Custodial Account: Can be completed in 1 to 2 weeks with the assistance of a qualified Wyoming estate planning attorney.
• Emancipation Proceedings in District Court: Generally takes 60 to 90 days from filing the verified petition under Wyo. Stat. § 14-1-203 to completing the mandatory court hearing after notice to parents.
• Small Estate Affidavit or Summary Distribution: Requires a mandatory 30-day waiting period after death under Wyo. Stat. § 2-1-201 before the affidavit can be filed with the County Clerk.
• Formal Probate Administration: Takes approximately 6 to 12 months in a Wyoming District Court, which includes the mandatory 3-month creditor claim window following publication of notice under Wyo. Stat. § 2-7-703.
