How to create a Last Will And Testament in Idaho

  1. List your assets and decide who should inherit them—this is the core of your last will and testament.
  2. Choose a personal representative (executor) you trust to manage your estate and carry out your instructions.
  3. Decide whether you want to use a will template or consult an attorney; if you use a template, ensure it complies with Idaho law.
  4. Write your will, including provisions for guardianship if you have minor children.
  5. Sign your will in the presence of two witnesses, and have them sign as well.
  6. For a self-proving will, you and your witnesses should sign an affidavit before a notary public.

Idaho Will Checklist: Before You Begin

Prepare properly to ensure your Idaho will is valid and reflects your wishes. Gather the following and understand state rules before drafting.

  • List your assets (real estate, bank accounts, investments, personal property) and decide who should inherit them (beneficiaries).
  • Identify an executor (personal representative) you trust; Idaho requires they be at least 18 and of sound mind.
  • Know Idaho's signing rules: you must sign in the presence of two witnesses, who must also sign in your presence and in each other's presence.
  • Decide on guardians for minor children, if applicable, and name alternates if your first choice is unavailable.
  • Consider whether to include a self-proving affidavit (notarized) to simplify probate later; it's recommended but not required.
  • Be aware that Idaho does not require filing your will with the court during your lifetime—store it safely and tell your executor where it is.

Frequently asked questions

What happens if I die without a will in Idaho?

If you die without a valid will, Idaho's intestacy laws determine who inherits your property. Your assets typically go to your closest relatives—spouse, children, parents, or siblings—in a specific order. This may not match your wishes, so creating a will ensures you have control.

Can I write my own will in Idaho without a lawyer?

Yes, you can write your own will in Idaho, as long as it meets the state's legal requirements. Using a reliable will template designed for Idaho can help. However, if your estate is complex or you have specific concerns, consulting an attorney is wise.

Is a will the same as a living will?

No. A last will and testament covers the distribution of your property after death, while a living will (or healthcare directive) outlines your wishes for medical treatment if you become incapacitated. Both are important parts of estate planning, but they serve different purposes.

Do I need to notarize my will in Idaho?

Notarization is not required for a will to be valid in Idaho, but it is highly recommended. A notarized self-proving affidavit allows the will to be accepted by the probate court without requiring your witnesses to testify, saving time and hassle for your family.
