If you die without a will in Idaho, state intestate succession law treats separate property and community property differently, and the outcome depends heavily on whether your children are also your surviving spouse's children. Idaho is a community property state, so understanding which category an asset falls into matters as much as who survives you.
If you do not want Idaho default rules to decide who gets your property, you can put a valid will in place in a short online session with the FastWill will builder, covered in detail near the end of this guide.
Key Takeaways
- Idaho's intestacy statute at Idaho Code section 15-2-102 treats separate property and community property differently.
- Your spouse automatically keeps their half of community property, and inherits your half too, when all your children are shared with that spouse.
- Separate property is split differently depending on whether you have surviving children or parents.
- Descendants who are not the surviving spouse's children take a share of separate property under a distinct formula.

How Idaho divides property when there is no will
Idaho Code section 15-2-102 addresses the surviving spouse's share, and because Idaho is a community property state, the rules split along two separate tracks depending on what type of asset is involved.
Community property
Your surviving spouse already owns half of the community property acquired during your marriage. Under intestate succession, your half of the community property also passes to your spouse, meaning your spouse ends up owning the entire community estate outright, regardless of whether you have children. This is one of the more spouse-favorable rules among community property states, but it only applies to property actually classified as community property.
Separate property, no surviving issue or parent
If you have no surviving children, grandchildren, or parents, your spouse receives your entire separate property estate as well.
Separate property, no issue but a surviving parent
If you have no children but a parent survives you, your spouse receives one-half of your separate property, with the remainder passing to your parent or parents.
Separate property with surviving children
If you have surviving children, your spouse receives one-half of your separate property, and your children divide the other half, regardless of whether those children are also your spouse's children. This is different from many other states, where the spouse's share depends on whether children are shared, and it is a detail Idaho families with blended households often overlook when assuming their situation works the same way a friend's did in a different state.
No spouse and no children
With no surviving spouse or children, Idaho Code section 15-2-103 directs the estate to your parents, then your siblings and their descendants, and further out if none of those survive you.
What about unmarried partners
Idaho intestacy law does not recognize an unmarried partner, no matter how long you were together or how your property was managed as a household. Only a legal spouse and blood or adopted relatives inherit under the statute.
What assets fall outside these formulas
Idaho Code section 15-2-102 only governs property titled solely in your name with no beneficiary designation. Life insurance proceeds, retirement accounts, and payable-on-death bank accounts pass directly to whoever is named, and property held jointly with right of survivorship passes automatically to the surviving co-owner, regardless of whether it is separate or community property. A house, vehicles, and personal belongings titled only in your name are typically what remains subject to the community-versus-separate-property split described above.
Does the estate still go through Idaho probate
Yes. An intestate estate in Idaho still goes through probate, applying the statutory heirs rather than your own instructions. Smaller estates may qualify for a simplified process, covered in our guide to the Idaho small estate affidavit. For a realistic sense of timing, see how long probate takes in Idaho.
Why write an Idaho will instead of relying on the community property split
The fact that separate property splits evenly between spouse and children, regardless of whether those children are shared, catches many blended families off guard. A will lets you decide exactly how separate property is divided, provide for a partner, and name a guardian for minor children instead of leaving those calls to Idaho Code chapter 2.
This matters even more if a significant part of your estate is separate property you owned before the marriage, such as a business, an inherited home, or investment accounts you never retitled into the community estate. For a broader look at what is at stake, see the consequences of dying without a will.
You can put a signed Idaho will in place with the FastWill will builder rather than leaving your separate property split by a formula that treats all surviving children the same way regardless of whose children they are.
Frequently Asked Questions
Does my spouse get all the community property if I die without a will in Idaho?
Yes. Your spouse already owns half of the community property and inherits your half as well, so your spouse ends up owning the entire community estate outright.
Does it matter if my children are not my spouse's children for separate property?
No, and that surprises many people. Idaho splits separate property evenly between the spouse and children regardless of whether the children are shared with that spouse.
What happens to separate property if I have no children but a parent survives me?
Your spouse receives half of your separate property, and your surviving parent or parents receive the other half.
Can an unmarried partner inherit under Idaho intestacy law?
No. Idaho's intestacy statute only recognizes a legal spouse and blood or adopted relatives, so an unmarried partner has no automatic right to inherit.
Is probate required if I die without a will in Idaho?
Yes. The estate still goes through Idaho probate court, it just follows the statutory heirs instead of your own instructions.
What happens to a jointly titled house in Idaho if there is no will?
If the house is titled jointly with right of survivorship, it passes directly to the surviving co-owner outside of both probate and the community and separate property rules described above.
