ADVERTISING: Advertorial: Idaho is a community property state — does your estate plan properly account for that?

Most people know they need a will or a trust. Far fewer understand how Idaho's community property laws shape what that will or trust can actually do. If you're married and living in Idaho, the distinction between community property and separate property isn't just a legal technicality — it can determine who owns what while you're alive and who inherits what when you die. Your estate planning documents need to take this into consideration, and do it yourself estate plans rarely get this right.

The Basic Rule

Idaho is one of only nine community property states in the country. Under Idaho Code § 32-906, almost everything acquired by either spouse during the marriage is presumed to be community property — owned equally, 50/50, by both spouses regardless of whose name is on the account, the title, or the paycheck.

This includes wages, investment accounts funded during the marriage, real estate purchased after the wedding, and most other assets accumulated while you were married and living in Idaho. It does not include property one spouse owned before the marriage, or assets received during the marriage as a gift or inheritance — those are separate property, as long as they haven't been commingled with marital property.

Why This Matters for Your Estate Plan

Here's the part that surprises many people: because community property is already half yours, your spouse can only give away their half in a will. You don't need to wait for your spouse to die to "inherit" your share of community property — you already own it.

This has real implications. If your spouse's will leaves "everything" to an adult child from a prior relationship, that bequest is limited to your spouse's half of the community estate. Your half remains yours. But if the community and separate property haven't been clearly identified and documented, this can trigger disputes, litigation, and significant family conflict — especially in blended families.

It also affects how you title assets and name beneficiaries. A beneficiary designation on a community property account controls only your spouse's half. If your spouse named a sibling as beneficiary on a brokerage account funded with marital earnings, that sibling may have a legitimate claim to 50% of the account — even if you expected it to pass entirely to your children.

The Commingling Problem

Separate property can lose its protected status if it gets mixed with community property in a way that makes it impossible to trace. A classic example: you owned a savings account worth $20,000 before you got married. Over the years, you deposited paychecks into that same account and paid marital expenses from it. Unless you kept meticulous records showing which funds were premarital, a court may treat the entire account as community property.

For inherited money or premarital assets, keeping those funds in a dedicated, separate account — and not commingling them with joint marital funds — is one of the simplest ways to preserve their character as separate property.

Moving to or from a Community Property State

If you previously lived in any state other than Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin, the classification of your assets may not be straightforward. Idaho law generally respects the character of property as it was acquired – following the laws of the state you lived in when you acquired it, but tracing what was earned where, and when, can become complicated quickly. If you've moved across state lines during your marriage, be sure to discuss this with your estate planning attorney.

Practical Steps

A well-drafted Idaho estate plan accounts for community property explicitly. This means identifying which assets are community and which are separate, ensuring your will or trust correctly disposes of only your share of community assets (or has provisions in which spouses have expressly agreed to how community property assets will be treated, regardless of default laws), reviewing beneficiary designations with community property principles in mind, and — for blended families especially — considering whether you need a marital property agreement that clearly defines property rights in both the case of divorce or death.

Community property law gives married couples a built-in form of joint ownership that can simplify some aspects of estate planning. But only if your documents are written to work with it.
