An Idaho last will and testament is a written document that states how a person's property, called the estate, should pass after death and who should carry out those wishes, called the executor. Idaho Code Title 15, Chapter 2 sets the signing and witness rules a will must meet to be valid. This Idaho last will and testament template follows those rules and can name a guardian for minor children.

You can revoke this Idaho last will and testament template at any time before your death. Revoke it either by signing a later will that cancels it, or by burning, tearing, canceling, or destroying it yourself or through someone you direct in your presence.[1.7] Idaho law also lets you attach a self-proving affidavit, so you and your witnesses sign before a notary and the probate court can accept the will without calling the witnesses to testify.[1.4]
An Idaho last will is also called a last will and testament, a will, or an estate planning will. Whatever name you use, the requirements in Idaho Code Title 15, Chapter 2 stay the same.
1. Think about your options. One thing to bear in mind, first, is if you would like to write the whole thing by hand (holographic will) or work with a fillable last will and testament form available here.
2. Indicate your details. Fill out your full name and address (the city, county, and state of residence) to determine the testator of the will. Check the details you entered as well as the rest of the section, which includes “Expenses and Taxes.”
3. Establish the executor. Determine the executor of your estate and specify their details: full legal name and place of residence, which will generally be within the same state the testator lives in because the majority of states enforce special policies on out-of-state executors. Although it is not obligatory, it’s a wise idea to appoint an additional person to act as an executor in case the first one is unwilling or incapable of executing your last will.
4. Establish the guardian (optional). If you have underage or dependent children, you can name a guardian for them in your will instead of leaving that choice to the court. Specify someone you know and trust to raise your children if you are no longer able to.
5. Indicate your beneficiaries. At this stage, you specify those who will receive your assets. Enter their full names, addresses, and your relationship to them (spouse, child, friend).
6. Assign property. List your assets and explain how you would like to distribute them amongst your beneficiaries if you have something under consideration other than dividing the assets equally. Assets may include money for outstanding arrears, real estate, shares, company control, cash, and any physical items of monetary value in your possession. Please notice that there are things that cannot be distributed in your last will and testament, such as joint and living will assets and life insurance.
7. Ask witnesses to finalize the document. Idaho Code Section 15-2-502 requires at least two witnesses who watch you sign the will or hear you acknowledge your signature.[1.2] Keep these points in mind when you choose witnesses:
At this point, you and your two witnesses sign the document after filling in your full legal addresses and names. Check each section carefully before you finalize it.
In regards to your spouse, Idaho is a community property state. Property and assets acquired during the marriage, or that increased in value with money earned during the marriage, belong to both spouses evenly. This can make it impossible to fully disinherit your spouse in this state.
Idaho law lets you exclude your spouse only from the property you manage on your own, known in Idaho as “separate property.” As an alternative, a prenuptial agreement can reallocate community property rights in different ways. Except for your spouse, you can disinherit any other family member.
Yes, you can change your will after signing it. As outlined by Idaho law, it is possible to alter or cancel your last will at any time. However, in case you’re obligated by a legal contract (e.g., a divorce agreement) not to do it, you might not be able to change or revoke your last will.
Idaho Code Section 15-2-502 allows another person to sign your last will for you, as long as it happens at your direction and in your presence.[1.2] If you also add a self-proving affidavit, the officer taking it before a notary can record that the signature was made at your direction.[1.4]
| Related documents | Instances when you might need to create one |
| Codicil | You need to make a single or several small alterations to your will. |
| Self-proving affidavit | You wish to expedite the probate later on. |
| Living will | You would like to indicate precisely what medical care you expect if you can’t express that yourself. |
| Living trust | You need extra confidentiality and safety when the time to distribute your possessions comes. |
Every state sets its own signing, witness, and self-proving rules for a valid will, so a template written for Idaho will not necessarily meet another state's requirements. If you need a will for somewhere other than Idaho, choose that state's template below.
