Estate Planning in Arizona

Arizona operates under community property law, one of only nine states to do so. Most assets acquired during marriage belong equally to both spouses regardless of whose name is on the title or who earned the income. This fundamental difference from common law states shapes every aspect of estate planning here, from how property passes at death to what a surviving spouse automatically inherits.

Like all states, Arizona recognizes formally executed wills and living trusts as valid estate planning tools. A standard will here requires 2A.R.S. § 14-2502Verified Sep 15, 2026View source adult witnesses, and adding a notarized self-proving affidavit can streamline the probate process later. The state also recognizes holographic (handwritten) wills, though these have stricter proof requirements and are more vulnerable to legal challenges. Be careful selecting witnesses: beneficiaries cannot serve in this role in Arizona, and using one could void their inheritance.

Arizona does not impose a state estate tax or inheritance tax, which means estates are only subject to the federal estate tax (currently exempting the first $15,000,00026 USC 2001(c), 2010; P.L. 119-21 §70106Verified Sep 15, 2026View source per person, or $30,000,00026 USC 2001(c), 2010; P.L. 119-21 §70106Verified Sep 15, 2026View source for married couples using portability). This is a meaningful advantage over the states that layer their own death taxes on top of the federal system.

Arizona does not require a revocable living trust to be notarizedA.R.S. § 14-10101 et seq. (Title 14, Chapter 11)Verified Jul 15, 2026View source. Arizona allows transfer-on-death deeds for real estate, enabling property to pass directly to named beneficiaries without probate. This is a significant probate avoidance tool that doesn't require creating a trust. Transferring property into a revocable trust does not trigger a property tax reassessment in Arizona, so property taxes remain at their current level.

Arizona automatically revokes an ex-spouse as beneficiary on life insurance, retirement accounts, and similar designations upon divorce. However, these automatic revocations can be overridden by a divorce decree or by re-designating the ex-spouse after the divorce. Arizona provides full creditor protection for inherited IRAs, meaning creditors cannot reach these funds—a protection not available in every state.

Arizona fully authorizes remote online notarization (RON) for estate planning documents, including wills, trusts, healthcare directives, powers of attorney. RON covers the notarization step; whether the whole signing can happen remotely also depends on whether the document's witnesses may attend by video.
