Quick answer: if personal property is at or under $200,000 and/or real property equity is at or under $300,000, an affidavit likely resolves that piece. Above those limits, Arizona still defaults to informal probate — simpler than many states, but still a court case. Check your own numbers with the Arizona small estate checker.
"Needing probate" in Arizona rarely means a courtroom
Informal vs. formal: the real distinction
Informal probate, the default, is processed largely through the registrar, with the personal representative then exercising broad statutory authority (including selling real estate) without further court steps. Formal probate brings a judge into the process and can specifically limit or expand that authority through a court order — typically reserved for contested estates, disputed wills, or situations needing judicial resolution.
What skips probate before the threshold question even matters
Regardless of a will, a dispute, or the estate's value, certain assets never enter probate: property jointly held with survivorship rights, payable-on-death or transfer-on-death accounts, life insurance and retirement accounts with a living named beneficiary, and anything already titled in a trust.
Who can serve if there's no will
Under A.R.S. 14-3203, priority generally goes first to the surviving spouse, then to other people who would inherit under Arizona's intestacy statutes. The Department of Veterans Affairs can serve for a veteran or veteran's spouse; a creditor can step in if no probate has been initiated within 45 days of death; a public fiduciary serves as the last resort.
The decision, in order
- Is personal property at or under $200,000, or real property equity at or under $300,000? If yes for either — the corresponding affidavit likely resolves that piece.
- Above those limits, or a personal representative is needed for other reasons — informal probate, Arizona's lighter-touch default.
- Disputed will, contested heirship, or a need for court-ordered restrictions — formal probate.
A local probate attorney can review your estate — many offer a free consultation.
Whichever path applies, the case is filed with the Superior Court of the county where the decedent lived — Maricopa, Pima, Pinal, and the rest of Arizona's 15 counties follow the same statutory framework.
