Probate Without a Will in Idaho: How Intestate Succession Works
An Idaho resident dies without a will. What happens to the house, the bank accounts, the business interest, the firearms, and the family cabin in McCall? The short answer is that Idaho’s intestate succession statute — Title 15, Chapter 2, Part 1 of the Idaho Code — takes the place of the missing will and dictates who inherits, in what shares. The longer answer is that the result is often not what the decedent would have chosen, takes longer than it needed to, and costs the family more than a properly drafted will would have.
Why Intestate Succession Matters
A will is the decedent’s instruction set: who gets what, who serves as personal representative, who serves as guardian for minor children, and which property bypasses probate altogether. Without a will, those choices revert to the legislature’s defaults. Those defaults are reasonable but generic. They do not account for blended families, estranged children, business succession, or the special situation of community property owned with a surviving spouse from a second marriage.
How Idaho Distributes an Intestate Estate
Idaho distinguishes between community property and separate property, and intestacy treats them differently.
Community Property
Under Idaho Code § 15-2-102(b), the surviving spouse inherits the decedent’s entire half of the community estate. If both spouses owned the house as community property and one dies without a will, the survivor ends up owning 100% of the house (her own community half plus the decedent’s community half). This is usually the result the decedent would have wanted, which is why intestate succession is least disruptive in a first-marriage, community-property household.
Separate Property When a Spouse Survives
Separate property — property owned before marriage, or received during marriage by gift, devise, or inheritance — follows a different rule. Idaho Code § 15-2-102(a) gives the surviving spouse the first portion of the separate-property estate plus a percentage of the remainder, with the balance going to the decedent’s descendants. Where the decedent had children from a prior relationship, the surviving spouse and the prior-marriage children divide the separate property under a statutory formula rather than by the decedent’s wishes.
No Surviving Spouse
Under Idaho Code § 15-2-103, where no spouse survives, the estate passes to descendants per stirpes (children, then grandchildren if a child predeceased). If no descendants survive, the estate passes to surviving parents, then to siblings and their descendants, then to more distant relatives by representation. Escheat to the State of Idaho is rare but possible where no qualifying relatives exist.
What Probate Looks Like Without a Will
Intestate probate in Idaho follows the same general framework as testate probate under the Uniform Probate Code as adopted in Title 15. The differences are who is appointed personal representative (under § 15-3-203 the priority shifts to the surviving spouse, then heirs) and how property is distributed (per the intestate statute instead of the will). Most intestate probates in Idaho can be handled as informal probate under § 15-3-301 et seq., which avoids most court hearings and runs faster than formal probate.
Property That Bypasses Intestate Succession Entirely
Not every asset goes through probate. The following typically pass outside the will (or in this case, outside the intestate statute) by their own contractual or registration mechanism:
- Joint-tenancy real property and bank accounts with right of survivorship.
- Life insurance policies with a named beneficiary.
- Retirement accounts (IRAs, 401(k)s) with a named beneficiary.
- Real property subject to a recorded transfer-on-death deed under I.C. §§ 15-15-101 to 15-15-114.
- Pay-on-death and transfer-on-death brokerage and bank accounts under I.C. § 15-6-301 et seq.
- Property held in a revocable living trust, which the decedent funded during life.
This last point is the most important practical takeaway: the easiest way to avoid intestate distribution and probate altogether is to fund a revocable living trust during life. See the Trusts page for a fuller discussion.
Special Situations
Blended Families
Blended families are the single most common scenario where intestate succession produces a result the decedent would not have wanted. The statutory split between the surviving spouse and prior-marriage children sometimes leaves both groups dissatisfied and the family home in a forced sale. Even a simple will avoids this.
Minor Children
Without a will nominating a guardian under I.C. § 15-5-202, the magistrate court will appoint a guardian based on the best interests of the child. Surviving family members often disagree, which produces contested guardianship litigation.
Firearms and NFA Items
Firearms pass through intestate succession like other personal property, but NFA-regulated items (short-barreled rifles, suppressors, machine guns) raise federal compliance issues. Transfer requires ATF Form 5 in an estate context. A properly funded Idaho gun trust avoids these issues by keeping the firearms in the trust rather than the probate estate.
The Better Path
None of this is complicated to fix. A simple Idaho will, executed in compliance with I.C. § 15-2-502 (signed by the testator and witnessed by two competent witnesses), substitutes the decedent’s wishes for the statutory defaults. A revocable living trust goes one step further by keeping the estate out of probate altogether. For Idaho residents with any of the special situations above, the cost of a properly drafted will or trust is dramatically less than the cost of intestate probate and the family conflict it tends to produce.
