How Much Does a Will Cost in Idaho?

Published June 11, 2026 7 min read

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. But the honest point is that a will is cheap because it doesn't avoid probate — it directs your estate through Idaho probate rather than skipping 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.

The catch: a will doesn’t avoid probate in Idaho

This is the part the price tag hides. A will is cheap because of what it doesn’t do: it does not avoid probate. A will simply tells the Idaho probate court who should get what and who should run the estate. Everything it covers still goes through probate — the public, months-long, fee-charging court process.

So the real cost of “just a will” isn’t the $0–$1,000 you pay now; it’s the probate your family pays later. To see that number for Idaho, read How Much Does Probate Cost in Idaho?.

Do you need more than a will in Idaho?

For a lot of people, a will is genuinely enough — especially renters, younger families, and anyone whose main assets (retirement accounts, life insurance) already pass by beneficiary designation outside probate.

You may want more than a will if you own a home and want to spare your family probate, value privacy, own property in more than one state, or want a plan for incapacity. That’s where a living trust comes in — it costs more up front but can avoid probate entirely. Compare the two honestly:

How to keep the cost down in Idaho

  • Use a quality online service for a truly simple estate. Several are free; paid ones run $0–$150. Make sure it’s Idaho-specific and includes a self-proving affidavit.
  • Bundle the basics. A will, a financial power of attorney, and a healthcare directive are cheaper together than separately — and the POA and directive matter while you’re alive, which a will never does.
  • Pay for an attorney when it’s not simple. Minor children, a blended family, a business, a special-needs beneficiary, or estate-tax exposure are all worth a real attorney’s time. A cheap will that’s invalid or unclear is the most expensive kind.

The honest takeaway

A will in Idaho costs $400 to $1000 with an attorney, or nearly nothing online — and for many people that’s all they need. Just go in clear-eyed about what you’re buying: a will directs your estate through probate; it doesn’t avoid it. If avoiding probate matters to you, price a living trust against what Idaho probate would actually cost your family, and decide from there.

Whatever you choose, sign it correctly with two disinterested witnesses, add the self-proving affidavit where Idaho allows it, and tell your executor where to find it.
