A Wyoming last will and testament is a written document that lets a testator say how their property passes to chosen heirs after death and name an executor to carry it out. It can also name a guardian for minor children. It is not a living will, which covers end-of-life medical care instead of property.
Wyoming law sets specific rules for who can sign a will, how many witnesses are needed, and when a handwritten will is valid. These rules and the steps to complete the form are covered below.

Wyoming Title 2, Chapter 6 sets the rules for a valid last will. The testator must be of legal age and sound mind, sign the will in writing, and have two competent witnesses sign it too, unless the will is entirely in the testator's own handwriting and qualifies as a holographic will.[1.3]
| Requirements | State laws | |
| Statutes | Title 2 – Wills, Decedents’ Estates and Probate Code; Chapter 6 – Wills | |
| Signing requirement | Two witnesses | § 2-6-112. Will to be in writing; number and competency of witnesses; signature of testator; subscribing witness not to benefit; exception |
| Age of testator | Legal age (18) and sound mind | § 2-6-101. Right to make and dispose; exception |

"All wills to be valid shall be in writing, or typewritten, witnessed by two (2) competent witnesses and signed by the testator or by some person in his presence and by his express direction."
Choose two witnesses who will not inherit anything under your will. Wyoming law limits what an interested witness can receive unless there are two disinterested and competent witnesses to the will.[1.3]
To make a Wyoming last will and testament, gather your personal details, decide on an executor and beneficiaries, and have two witnesses ready to sign. The list below outlines what you will need before you begin filling out the form.
1. Think about your possibilities. Before beginning, it’s best to decide if you would like to use the assistance of an attorney or create the whole document on your own. In case you want to create the last will by yourself, select the type you will go for: a handwritten will or maybe a free will forms.
2. Specify your details. Add your full legal name and address (city, county, and state) to identify yourself as the testator. Then review the rest of the section, including the “Expenses and Taxes” subsection, to confirm the details you entered.
3. Choose the executor (or executrix). This section names who will carry out your will, so add their full name along with their city, county, and state of residence. Many people choose an executor who lives in Wyoming to make the process easier. You can also name a backup executor to serve if your first choice is unable or unwilling to act.
4. Appoint the guardian (optional). You are able to appoint a trusted person as a guardian in case you have underage or dependent children that must be taken care of. If there are no instructions pertaining to what person should look after your kids, the guardian will be appointed by the court.
5. Indicate your beneficiaries. This is where you indicate those who will receive your property. For each beneficiary, state the next particulars: full legal name, address, and the way they are related to you.
6. Allocate assets. List your property and explain the way in which you want to distribute it among your beneficiaries if you have something under consideration other than dividing the property evenly. Money for arrearage, realty, stocks, business control, cash, and any tangible items of financial value you possess can be mentioned in the last will. Please notice that there are things that can’t be distributed in the last will and testament, for instance, shared and living will assets and life insurance.
7. Ask witnesses to sign the document. Wyoming law requires at least two competent witnesses to sign your will for it to be valid.[1.3] Choose witnesses who are not named as beneficiaries. Wyoming law limits what an interested witness can receive unless there are two disinterested witnesses to the will.[1.3]
Once you and your witnesses have filled in your full legal names and addresses, sign the document together. Read each section carefully before you sign.
Other Wyoming Forms
A Wyoming last will is legal when it is in writing or typewritten, signed by the testator (or by someone else at the testator's direction and in their presence), and witnessed by two competent witnesses.[1.3] The testator must also be of legal age and sound mind when they sign.[1.1]
Wyoming also allows witnesses to attend by audio-video technology instead of in person, as long as they can see and hear the testator sign.[1.3] The law also protects a will if a witness was competent when they signed but later becomes incompetent, since that does not stop the will from being probated.[1.3]
A Wyoming last will can fail if it is not in writing. It can also fail if the testator did not sign it, or direct someone else to sign in their presence, or if it lacks the signatures of two competent witnesses, unless it qualifies as a valid holographic will.[1.3] Wyoming law also limits what a witness can receive under the will if that witness stands to benefit from it, unless two disinterested witnesses signed too.[1.3]
Yes. Wyoming law lets a testator prepare a will without an attorney, as long as it is in writing, signed by the testator, and witnessed by two competent witnesses.[1.3] A will written entirely in the testator's own handwriting and signed by the testator can also be valid as a holographic will, even without witnesses.[1.2]
To make a Wyoming will without an attorney, put your wishes in writing, sign the document yourself (or direct someone else to sign for you in your presence), and have two competent witnesses sign as well.[1.3] Follow the steps below to fill out a Wyoming last will and testament form on your own.
Rules about excluding a spouse or children from a will vary by state, and many states give a surviving spouse certain minimum rights regardless of what the will says. Because these rules are specific and can significantly affect your estate plan, talk to a local attorney before you leave out a spouse or child.
If your original will cannot be found, a court may be reluctant to accept a copy in its place, and proving your wishes can become more difficult. Keep your original will in a safe place and let your executor know where to find it.
Wyoming law allows someone else to sign the will for the testator, as long as it is done at the testator's direction and in their presence.[1.3] This can help a testator who is physically unable to sign personally. The person signing on the testator's behalf should still do so in front of the two required witnesses.
