Arizona Community Property Laws: What Married Couples Need to Know

Arizona is one of nine community property states. If you're married and living here, nearly everything you earn or acquire during the marriage belongs equally to both spouses — regardless of whose name is on the account or deed. This has massive implications for estate planning, taxes, and what happens when one spouse dies.

Community Property vs. Separate Property

Under A.R.S. § 25-211, assets acquired during marriage are presumed community property. Each spouse owns an undivided 50% interest.

Community property includes:

• Income earned by either spouse during the marriage
• Real estate purchased during the marriage (even if only one name is on the deed)
• Bank accounts funded with marital earnings
• Retirement contributions made during the marriage
• Business interests acquired or grown during the marriage

Separate property includes:

• Assets owned before the marriage
• Inheritances received by one spouse (even during the marriage)
• Gifts given specifically to one spouse
• Personal injury awards (the pain and suffering portion)

The critical rule: separate property loses its status if you commingle it with community funds. Deposit your inheritance into a joint checking account, and you've potentially converted it to community property. Keep separate assets in separate accounts with clear documentation.

CPWROS vs. Joint Tenancy: The Tax Difference

Both Community Property with Right of Survivorship (CPWROS) and Joint Tenancy with Right of Survivorship (JTROS) bypass probate — the surviving spouse gets full ownership automatically when the first spouse dies. But the federal tax treatment is dramatically different.

Joint Tenancy — only the deceased spouse's half receives a step-up in cost basis under IRC § 1014(a). The surviving spouse keeps their original cost basis on their half.

CPWROS — under IRC § 1014(b)(6), both halves receive a full step-up to fair market value at death. This is the double step-up.

Real Numbers

A couple buys a home in 2005 for $250,000. By 2026, it's worth $650,000.

If held as Joint Tenancy: When the first spouse dies, the survivor's new basis is $450,000 ($325K stepped-up half + $125K original half). Selling for $650,000 creates a $200,000 taxable gain. At 15% federal capital gains: $30,000 tax bill.

If held as CPWROS: Both halves step up to $650,000. Selling for $650,000 creates zero taxable gain. $0 tax bill.

For couples with appreciated real estate — which is most Arizona homeowners given the Sun Belt appreciation of the past two decades — the difference between CPWROS and joint tenancy can be tens of thousands of dollars in avoided capital gains taxes.

How to Switch From Joint Tenancy to CPWROS

If your deed currently reads "as joint tenants with right of survivorship," you can convert it to CPWROS by recording a new deed. Both spouses execute a quitclaim deed from "[Spouse A] and [Spouse B], as joint tenants" to "[Spouse A] and [Spouse B], as community property with right of survivorship."

This is a title change only — no transfer tax, no reassessment, no Affidavit of Property Value required (because there's no change in beneficial ownership). Recording fee: $30.

What Happens Without Survivorship Language

Plain "community property" without the right of survivorship addition does not bypass probate. When the first spouse dies, their 50% community interest passes through their estate — either by will or by intestacy if there's no will.

Many Arizona couples hold title as "husband and wife" without any survivorship language. This is treated as standard community property, meaning the deceased spouse's half goes through probate. Adding CPWROS language fixes this.

Blended Family Complication

CPWROS automatically gives the surviving spouse 100% ownership. For couples in second marriages with children from prior relationships, this may not be the desired outcome. The surviving spouse could then leave everything to their own children, effectively disinheriting the deceased spouse's biological children.

In blended families, a revocable living trust with specific distribution instructions often works better than CPWROS — it can provide for the surviving spouse's housing needs while preserving the inheritance for biological children.

Separate Property That Looks Like Community Property

Common traps:

• Pre-marital home with mortgage payments made during marriage — the appreciation attributable to community-funded mortgage payments may be community property
• Business started before marriage that grew during marriage — the growth attributable to spousal effort during marriage may be community property
• Inherited funds deposited into a joint account — commingling can destroy the separate property characterization

Document separate property with a property agreement. Keep inherited assets in a separate account titled in one spouse's name only. A written log of separate property — with account numbers and dates — can prevent disputes later.

The Arizona Basic Estate Planning Kit includes a community property classification worksheet and a deed optimization checklist for CPWROS conversion.
