Idaho Divorce and Inheritance: Is Your Inheritance Protected?

Under Idaho Code § 32-903, inheritances are classified as the separate property of the receiving spouse. In theory, your inheritance is not subject to division in a divorce. In practice, that protection depends entirely on what you did with the money after receiving it.

The Default Rule

Property acquired during marriage by gift, bequest, devise, or descent belongs solely to the receiving spouse. This covers cash inheritances, inherited real estate, inherited investment accounts, and any other property passed through a will, trust, or intestate succession.

The protection is automatic — you do not need a prenuptial agreement to keep an inheritance separate. But this protection is fragile.

How Inheritances Lose Separate Status

Commingling with community funds. Depositing inherited money into a joint bank account used for household expenses is the most common way to destroy the separate character. Under Gapsch v. Gapsch, once separate and community funds are mixed and treated as one, the entire account is presumed community property.

Using inheritance for community purposes. If you used inherited money to renovate the marital home, pay off a joint credit card, or fund a family vacation, those funds may be treated as a gift to the community. Recovering them requires proving the expenditure was not intended as a contribution to the marriage.

Titling inherited property jointly. Under Idaho Code § 32-906(2), property conveyed from one spouse to the other is presumed to become the receiving spouse's separate property. But adding your spouse's name to an inherited asset — putting their name on the deed of an inherited house, for example — can be interpreted as a gift to the community, depending on the circumstances and any written agreements.

Income from inherited property. Here is the rule that surprises most people: under Idaho Code § 32-906(1), income generated by separate property during the marriage is community property. If you inherit a rental property, the rental income collected during the marriage belongs to both spouses. If you inherit stocks, the dividends earned during the marriage are community income. The underlying inherited asset remains separate, but its earnings do not.

The Tracing Requirement

If your inheritance was commingled — even partially — you need to trace the separate funds to prove their origin and continuous identity. Idaho courts require tracing to "reasonable certainty and particularity" under the standard from Batra v. Batra.

Successful tracing requires:

• The estate distribution statement or trust disbursement record showing the inheritance amount and date
• Bank statements showing the deposit into a specific account
• A transaction history demonstrating that the inherited funds were not consumed by community spending
• If the inherited funds were reinvested, documentation showing the chain from the original inheritance to the current investment

In Herr v. Herr (2021), the Idaho Supreme Court divided an investment account 50/50 because the husband could not trace his inherited contributions through the account's subsequent transactions. The commingling destroyed his separate-property claim despite the clear inheritance origin.

Protecting an Inheritance During Marriage

If you receive an inheritance during your marriage and want to preserve its separate character:

Keep it in a dedicated separate account titled in your name alone. Do not use this account for any household expenses.

Do not add your spouse to the title of inherited real estate or accounts.

Document the source with the estate distribution letter, probate court records, or trust disbursement statement. Keep these documents permanently.

Consider a postnuptial agreement declaring that income from the inherited property will remain separate. This is the only way to override Idaho's default rule that separate-property income is community property.

Track income separately. If the inherited property generates income, keep that income in a separate account and document that it derives from separate property. Even with the community income rule, having clean records is essential if you later negotiate an offset or seek to demonstrate the separate character of the underlying asset.
