How Much Does a Will Cost in Idaho?

Quick answer

A simple will in Idaho typically costs about $400 to $1,000 with an attorney (some Boise firms quote roughly $695 for one person, $895 for a married couple's reciprocal wills), and $0 to $150 online. Idaho also recognizes handwritten (holographic) wills, so a valid will can cost nothing. A will directs an estate through Idaho probate rather than avoiding it. If avoiding probate is the goal, that's a living-trust question.

A simple will in Idaho is genuinely inexpensive — $400 to $1000 with an attorney, and as little as $0 online. The price is low for a reason: a will is a relatively simple document. The cost climbs only when your situation is complicated — minor children and a guardianship decision, a blended family, a business, or potential estate tax.

What makes a will valid in Idaho

A standard Idaho will must be in writing and signed by the testator (or by another at the testator's direction and in their presence), and signed by at least two witnesses, each of whom witnessed the signing or the testator's acknowledgment of the will (Idaho Code §15-2-502).

The witnesses should be disinterested — that is, not people who inherit under the will — so no one can later argue they had a reason to lie about the signing. Get that one detail wrong and the gift to an interested witness (or the whole will) can be challenged.

Can you write your own will by hand in Idaho?

Idaho recognizes holographic (handwritten) wills. Under Idaho Code §15-2-503 a will is valid without witnesses if the signature and the material provisions are in the testator's own handwriting. They are legal but easier to contest and harder to probate than a witnessed will.

Even where a handwritten will is legal, it’s the riskiest way to do it: no witnesses means no one to confirm it was really you and that you weren’t pressured, and ambiguous handwriting is a gift to anyone who wants to contest it. A typed, witnessed, self-proved will costs very little and avoids all of that.

The self-proving affidavit (a small step that saves a big headache)

Idaho allows a self-proving will: the testator and two witnesses sign a notarized affidavit under Idaho Code §15-2-504, so the witnesses generally don't have to be located or testify later. A typed, witnessed, self-proved will is the easiest to admit to probate.

Without it, your witnesses may have to be tracked down years later to confirm they watched you sign — which can be impossible if they’ve moved, lost touch, or died. It’s one of the cheapest, highest-value things you can add to a will.

What a will does not do in Idaho

A will directs an estate through probate; it does not remove assets from it. A will tells the Idaho probate court who receives what and who administers the estate. Property governed by the will still passes through probate — the court-supervised, public process.

The cost of the document and the cost of probate are therefore separate figures. For what probate itself costs in Idaho, see How Much Does Probate Cost in Idaho?.

What passes outside probate in Idaho

Assets transfer outside probate only by operation of law or contract, regardless of what a will says. The recognised mechanisms are:

Beneficiary designations — retirement accounts, life insurance, and payable-on-death accounts pass to the named beneficiary.
Joint ownership with right of survivorship — passes to the surviving owner.
Transfer-on-death instruments, where Idaho authorises them.
Assets titled into a funded living trust.

A will has no effect on any asset transferred by these routes. For the Idaho figures on the trust alternative, see How Much Does a Living Trust Cost in Idaho?, and for the documented differences between the two instruments, Will vs. Trust: How They Differ.

What affects the price in Idaho

Published pricing varies with these factors:

Preparation route. Online will services are the lower end of the range; attorney drafting is the upper end. Idaho-specific forms and a self-proving affidavit are not included by every service.
Bundling. A will, a financial power of attorney, and a healthcare directive are commonly quoted together at less than the sum of their separate prices. The power of attorney and directive operate during life; a will operates only at death.
Estate complexity. Minor children, blended families, business interests, special-needs beneficiaries, and estate-tax exposure are the factors attorneys cite for higher quoted fees.
