In short
Idaho is a community property state. Under Idaho Code § 32-906, property either spouse acquires after marriage is community property, and under § 32-912 neither spouse may sell, convey or mortgage community real estate unless the other joins in signing. Spouses can hold a home as community property with right of survivorship (§ 15-6-401), and the IRS lists Idaho among the states covered by Publication 555.
What counts as community or separate property?
The Idaho statutes start from a simple split:
- Separate property (§ 32-903): property either spouse owned before marriage, property acquired by gift, bequest, devise or descent, and property bought with the proceeds of separate property.
- Community property (§ 32-906): “all other property acquired after marriage by either husband or wife.”
Two details matter for homebuyers. First, § 32-906 also makes the income of both separate and community property, including rents and profits, community property, unless a deed or a written agreement of both spouses says otherwise. Second, the statute’s test is when the property was acquired, not whose name appears on the deed. Publication 555 adds that property that cannot be identified as separate is treated as community property.
A home bought with separate funds, such as money owned before marriage or an inheritance, can stay separate. If you mix separate and community money, Publication 555 treats the part bought with separate funds as separate; keep records.
Who must sign when you buy, sell or borrow?
Section 32-912 gives either spouse the right to manage community property and bind it by contract, with one exception that applies to your home: neither spouse may sell, convey or encumber community real estate unless the other joins in the sale agreement, the deed or the instrument. A mortgage or deed of trust encumbers the real estate, so § 32-912 also applies when you borrow against the home.
There are two statutory ways around this:
- Power of attorney. A spouse may give the other, by express power of attorney, the complete power to sell, convey or encumber community property.
- Transfers between spouses. Under § 32-906(2), property one spouse conveys to the other is presumed to be the grantee’s sole and separate estate, and only the grantor needs to sign. The income from that property stays community unless the deed says otherwise.
Idaho Housing says it allows “sole and separate” transactions for FHA, VA and conventional loans, following agency guidelines, and counts the income of all spouses, borrowing or not, when it tests eligibility for its tax-exempt first loan. Ask your lender how it treats a spouse who is not on the loan.
How can spouses hold title?
The statutes lead to a few practical options. The table summarizes what the cited sections say.
| Way to hold the home | What the Idaho Code says |
|---|---|
| Community property | Default for property acquired after marriage (§ 32-906). Both spouses sign to sell or mortgage (§ 32-912). |
| Community property with right of survivorship | At one spouse’s death, the home passes to the survivor. It must be expressly declared in the grant, transfer or devise (§ 15-6-401). |
| Separate property of one spouse | Pre-marriage or gifted or inherited property (§ 32-903), or by written agreement of both spouses (§ 32-906). |
| Revocable trust | Community property placed in a trust stays community if the trust says so and can be changed jointly (§ 32-906A). |
Spouses can also set the rules in advance. A premarital agreement must be in writing, signed by both parties and acknowledged as conveyances of land are (§ 32-922), and may cover ownership, management and what happens at separation, divorce or death (§ 32-923).
What happens at divorce or death?
Divorce. Under § 32-712, the court assigns community property and the homestead “in such proportions as the court… deems just.” Unless there are compelling reasons otherwise, the law calls for a substantially equal division in value, considering debts. Factors that can change this include the length of the marriage, each spouse’s health, income and needs, and any antenuptial agreement. Publication 555 adds that dividing community property in a divorce does not by itself produce a gain or loss for tax purposes.
Death. If there is no will, § 15-2-102 passes the decedent’s one-half of the community property to the surviving spouse. With a survivorship estate under § 15-6-401, the home belongs to the surviving spouse by the deed itself.
A worked example: the tax basis after a death
This is an illustration, not a prediction. A couple buys a home for $300,000 using community funds. Years later one spouse dies and the home is worth $500,000. Publication 555 says that, when at least half of the community property’s value is included in the deceased spouse’s estate, the total fair market value generally becomes the basis of the whole property. The survivor’s basis would be about $500,000 instead of $300,000, which can reduce taxable gain on a later sale. Our guide to capital gains on a home sale explains the other rules. For your situation, ask a tax professional.
Where this fits in your purchase
Both spouses should read the purchase contract and the deed before closing, since the title and the signatures are set at that point.

Frequently asked questions
Do both spouses have to sign to sell a house in Idaho?
Yes for community real estate. Idaho Code § 32-912 says neither spouse may sell, convey or encumber it unless the other joins in the agreement or deed. The exceptions are an express power of attorney, and a conveyance from one spouse to the other under § 32-906(2).
Is a home bought before marriage community property?
Section 32-903 keeps property owned before marriage as the owner’s separate property. Income from separate property is community unless the spouses agree otherwise in writing (§ 32-906). Publication 555 treats a home bought partly with community funds and partly with separate funds as partly community, so keep records.
What is community property with right of survivorship?
It is a way to hold real estate that sends the home to the surviving spouse at the first death. Idaho Code § 15-6-401 requires that the grant or transfer expressly declare this form of ownership.
How is a house divided in an Idaho divorce?
The court assigns community property in proportions it deems just. Under § 32-712 the starting point is a substantially equal division in value, considering debts, unless there are compelling reasons otherwise.
Does community property change my taxes?
It can. IRS Publication 555 covers Idaho, and explains how married couples who file separately split community income, and how the basis of community property generally resets to fair market value when a spouse dies.
