Wyoming Will Requirements at a Glance
Here are the exact rules for making a valid will in Wyoming:
| Minimum age to make a will | 18 |
| Witnesses required | 2 |
| Notarization required | NO — notarization is not required to make a valid will in Wyoming, but a notarized self-proving affidavit (signed by the testator, both witnesses, and a notary) may streamline probate by eliminating the need for witnesses to testify in court (Wyo. Stat. § 2-6-114) |
| Handwritten (holographic) will allowed | YES — Wyoming recognizes holographic wills under Wyo. Stat. § 2-6-113; the will must be entirely in the testator’s own handwriting and signed by the testator; no witnesses are required for a holographic will, though it cannot be made self-proving |
| Self-proving affidavit available | YES — under Wyo. Stat. § 2-6-114, the testator and both attesting witnesses may sign a sworn affidavit before a notary public declaring the will was executed freely, without undue influence, and while the testator was of sound mind; a self-proving will may be admitted to probate without requiring witnesses to appear and testify; remote notarization via audio-video technology is also permitted |
| Statutory will form | NO — Wyoming does not offer an official statutory fill-in-the-blank will form; residents may draft a will using an attorney, online service, or template that complies with Title 2 Chapter 6 requirements |
What a Wyoming Will Does (and Doesn’t Do)
a Wyoming will allows you to name a personal representative (executor) to manage your estate, name a guardian for minor children, direct how your probate assets are distributed among beneficiaries, and make specific bequests of personal or real property
What a Wyoming will does NOT control: a Wyoming will does not control assets that pass outside probate, including life insurance proceeds with a named beneficiary, retirement accounts (401(k), IRA) with a named beneficiary, payable-on-death (POD) or transfer-on-death (TOD) accounts, property held in joint tenancy with right of survivorship, and assets held in a living trust
Oral wills in Wyoming: NO — Wyoming does not recognize oral (nuncupative) wills; all wills must be in writing under Wyo. Stat. § 2-6-112
How to Update or Revoke a Wyoming Will
a Wyoming will may be amended by executing a codicil, which must meet the same formalities as a will (written, signed, attested by two witnesses); a will may be revoked by executing a subsequent will or codicil that expressly revokes it or is inconsistent with it, or by a physical act such as burning, tearing, canceling, or destroying the will with intent to revoke (Wyo.
Stat. § 2-6-117); divorce or annulment automatically revokes any provisions benefiting the former spouse unless the will expressly provides otherwise (Wyo. Stat. § 2-6-118)

Other Wyoming will-making rules: Wyoming permanently allows remote witnessing — witnesses may observe the testator sign the will in real time via audio-video communication technology and may sign electronically (2023 amendment to Wyo.
Stat. § 2-6-112); an interested witness (one who is also a beneficiary) does not invalidate the will, but any bequest to that witness is void unless at least two additional disinterested witnesses also attested the will; Wyoming does not recognize purely electronic wills despite allowing remote witnessing — the will itself must be on paper;
Wyoming also enacted the Community Property Trust Act allowing married couples to opt into community property treatment for assets in a specific trust, which may affect estate planning

Understanding Wyoming Estate Planning
Getting started with Wyoming estate planning is the single best gift you can give your family. A valid Wyoming will lets you decide who inherits, name an executor, and name a guardian for your children — instead of leaving it to a default state formula.
When people look into Wyoming estate planning, the real answer comes down to the state’s execution rules: your age, the number of witnesses, and whether you make it self-proving. If any part of Wyoming estate planning is unclear, your state court’s self-help center can point you to the official forms and resources.
