The Commingling Problem

One of the most common and contentious issues in Arizona divorces is commingling — when separate property gets mixed with community property to the point where it can no longer be clearly identified. For example, if you inherited $50,000 and deposited it into a joint bank account that both spouses used for household expenses, that inheritance may lose its separate property character. The burden of proof falls on the spouse claiming the property is separate.

To protect separate property, it is critical to keep it in a separate account, maintain clear records of its origin, and avoid mixing it with community funds. If you are going through a divorce and believe you have separate property that has been commingled, you will need to trace the funds back to their source — a process that can require bank statements, tax returns, and sometimes forensic accounting.

How Is Community Property Divided?

When a couple divorces in Arizona, the court divides community property in a manner that is equitable — which in most cases means equal. Under A.R.S. § 25-318, the court is required to divide community property and community debts equitably, though not necessarily equally. In practice, Arizona courts start with a presumption of equal division and deviate from it only when there is a compelling reason.

Factors the Court May Consider

While a 50/50 split is the norm, courts have discretion to consider several factors when dividing property.

How Division Works in Practice

In most uncontested divorces, the spouses negotiate the division of property themselves and memorialize the agreement in a Consent Decree. The court will typically approve any reasonable agreement the parties reach.

For assets that cannot be easily split — like a house — the couple has several options. They can sell the property and divide the proceeds equally. One spouse can buy out the other's share. Or they can agree that one spouse keeps the house in exchange for the other spouse receiving assets of equivalent value (such as a larger share of retirement accounts or other financial assets).

Community Debts

Arizona's community property laws apply to debts as well as assets. Under A.R.S. § 25-215, debts incurred by either spouse during the marriage are presumed to be community debts, and both spouses are equally responsible for them.

This means that if your spouse ran up credit card debt during the marriage, you are likely responsible for half of it — even if you did not know about the spending and even if the credit card was in your spouse's name only. Common community debts include:

Mortgages taken out during the marriage on community property.

Car loans for vehicles purchased during the marriage.

Credit card debt incurred during the marriage, regardless of whose name is on the card.

Medical bills for treatment received during the marriage.

Student loans may be community debt if the education benefited the community (though this is a complex area that courts evaluate case by case).

Important Exception: Debts After Separation

Debts incurred after the date of service of the divorce petition are generally the separate obligation of the spouse who incurred them. This is one reason why the date of service is so important — it marks the dividing line between community and separate obligations.

Protecting Your Interests

If you are going through a divorce in Arizona, here are the most important steps you can take to protect your property interests.

Document everything. The Affidavit of Financial Information requires a complete accounting of all assets and debts. Be thorough and honest. Failing to disclose assets can result in serious legal consequences, including the court awarding the hidden asset entirely to the other spouse.

Identify separate property early. If you have assets that you believe are separate property — inherited money, property owned before marriage, gifts — gather the documentation now. Bank statements, inheritance records, gift letters, and pre-marital account statements can all help establish the separate character of your property.

Do not move or hide assets. When a divorce petition is filed in Arizona, a Preliminary Injunction automatically takes effect. This court order prohibits both spouses from transferring, selling, or disposing of community property outside the normal course of business. Violating this injunction can result in sanctions and an unfavorable property division.

Understand the full picture. Many people focus on the assets they can see — the house, the cars, the bank accounts — and overlook less visible assets like retirement accounts, stock options, business interests, and intellectual property. A complete financial disclosure is essential. For a full breakdown of what a divorce costs in Arizona, see our 2026 cost guide.
