Community property in Arizona, explained

You got married in October and your paycheck landed in November. Who owns it? In Arizona, both of you do. Community property law is the quiet rule that changes the ownership of almost everything you acquire once the marriage starts, and it applies whether or not you ever think about it.

The basic rule

Arizona is one of nine community property states. Under A.R.S. § 25-211, any property acquired by either spouse during the marriage is presumed to be community property, owned half by each spouse. This applies to wages, business earnings, retirement contributions, and almost everything else you acquire during the marriage.

The rule doesn't care whose name is on the account. If the paycheck was earned during the marriage, both spouses own half of it. This surprises newly-married clients more than any other single thing in the estate plan.

What stays separate

A.R.S. § 25-213 defines separate property: what each spouse owned before the marriage, what either spouse receives by gift or inheritance during the marriage, and anything acquired after a legal separation or divorce. Interest and appreciation on separate property generally remain separate. Wages earned on separate property generally become community.

In practice, separate property only stays separate if the paper trail supports the claim. A savings account you brought into the marriage with $40,000, kept in your name, never deposited marital funds into, and used only for separate-property expenses, stays separate property ten years later. The same account if you deposited paychecks into it, paid household bills from it, or transferred marital funds in and out of it is almost certainly community property by the time a court is asked.

Commingling is what usually ends separate property

The concept of commingling is simple. Mix separate property with community property in a way that makes tracing impossible, and the whole account becomes community. Mix a small amount of community into a separate account and the account may be partly separate, but the burden is on you to trace it.

If you bring $100,000 of pre-marriage savings into the marriage and deposit it into a joint account with your spouse's paychecks, that $100,000 is at risk of becoming community. If you use that account to pay the down payment on a house titled in both names, the house is community property, your separate contribution is gone as an identifiable asset, and at divorce or death that fact matters.

The fix isn't paranoid separation. The fix is documentation. Keep inheritances and pre-marriage assets in accounts in your name only. Don't deposit community earnings into those accounts. Pay separate expenses out of separate accounts when possible. If you plan to use separate funds for a shared purpose, document the transaction in writing at the time.

The big surprises

Inheritances. A substantial inheritance is separate property when received (A.R.S. § 25-213). How quickly it becomes community depends entirely on what you do with it. Deposit it into a joint account and the rule changes.

Business interests. If you owned a business before the marriage, the business itself may remain separate. But the growth of the business during marriage, your labor during marriage, and any reinvestment of community earnings into the business can create community interests. Without documentation, an Arizona court may find the business is partly separate and partly community, and neither spouse likes the result.

Debt. Arizona community property applies to debt too. Debts incurred for community purposes during the marriage are community debts, and creditors can generally reach community property to satisfy them (A.R.S. § 25-215). Debts one spouse brings into the marriage stay that spouse's separate debt and cannot be satisfied from the other spouse's separate property. Signing a loan application with the word 'I' after marriage doesn't remove community property from the creditor's reach.

Retirement accounts. Contributions to a retirement account during marriage are community property even though the account is titled in one spouse's name. The pre-marriage balance is separate. Growth on that balance is also generally separate. But contributions made during marriage and their growth are community property.

Postnuptial agreements and characterization

If you and your spouse want a different allocation than the default, a postnuptial agreement can convert community property to separate, or separate to community, or specify the characterization of a particular asset. This is routine in blended families, in business ownership situations, and in plans where each spouse has significant pre-marriage assets.

The agreement must be in writing, must be entered into voluntarily with each spouse represented by independent counsel, and must provide fair disclosure of assets. Done right, a postnuptial agreement is one of the cleanest tools in an estate plan because it resolves characterization questions before they ever reach a court.

Titling and deeds after marriage

Review how major assets are titled after you get married.

Real estate. Deeds should reflect the ownership you actually want. Joint tenancy with rights of survivorship passes to the surviving spouse outside of probate. Community property with right of survivorship accomplishes the same thing and adds a full step-up in basis for the surviving spouse at death (A.R.S. § 33-431). Tenancy in common is rarely right for spouses in Arizona.

Bank and brokerage accounts. Decide intentionally which are joint and which are separate. Don't let the branch employee decide by default at account opening.

Business interests. Operating agreements, partnership agreements, and corporate bylaws should reflect marital status. A buy-sell provision that assumes the owner is single leaves gaps at death or divorce.

What community property means for estate planning

Your will or trust can only give away your half of community property. Your spouse already owns the other half, and the marriage contract gives them veto power over what you leave, in practice if not in statute. This is why almost every Arizona estate plan for married couples is built around a joint revocable trust rather than two separate wills.

At death, Arizona law (A.R.S. § 14-2102) distributes community property differently depending on whether all children are also children of the surviving spouse. Reading that statute before you sign anything saves families thousands of dollars and serious grief later.
