Picture this: You die in Phoenix. It’s July. It’s 115 degrees outside, and your family is standing in the kind of heat that makes the asphalt bubble and the steering wheel untouchable. They should be inside. They should be by the pool. Instead, they’re trying to figure out what the hell an “intestate petition” is and whether they need to file it at the Maricopa County Superior Court. In Phoenix. In July. Without you. Because you didn’t take 20 minutes to write a will.
Arizona has some of the more streamlined probate laws in the country. It’s still a nightmare without a will. Here’s what actually happens.
Arizona’s Intestate Succession Law
Arizona is a community property state — one of nine in the U.S. This fundamentally shapes how intestacy works here. Like Washington, Arizona divides marital property into two buckets: community property (acquired during the marriage, owned 50/50) and separate property (owned before marriage, or received as a gift or inheritance during marriage).
Arizona intestacy is governed by Title 14 of the Arizona Revised Statutes (the Uniform Probate Code, which Arizona adopted).
Community property — surviving spouse:
Your half of all community property goes to your surviving spouse automatically. They already own their half. This part is simple and clean.
Separate property — surviving spouse and children:
- All children are also the spouse’s children? Spouse gets all separate property.
- Children from a prior relationship exist? Spouse gets half the separate property; prior-relationship children split the other half. Your spouse’s share of your separate property just got cut in half.
Separate property — surviving spouse, no children:
Spouse gets everything.
No surviving spouse, but children:
Children share equally.
No spouse, no children:
- Parents inherit.
- No parents? Siblings.
- No siblings? Nieces and nephews.
- Keep going — grandparents, aunts, uncles, cousins.
- Truly no one? Estate escheats to Arizona.
Unmarried partners: Arizona does not recognize common-law marriage formed after 1913 (it abolished it then, with a narrow exception for marriages validly formed elsewhere). A live-in partner with no marriage certificate gets nothing without a will, regardless of relationship length.
What Probate Looks Like in Arizona
Arizona probate runs through the Superior Court in the county where you lived. Arizona follows the Uniform Probate Code (UPC), which was designed to modernize and simplify the probate process. Compared to many states, Arizona probate is relatively efficient. “Relatively efficient” still means months of court process.
Timeline: Arizona’s UPC process typically takes 6–12 months. The mandatory creditor claims period is 4 months from when creditors are notified. Simple estates with clear heirs and liquid assets move faster. Real estate, business interests, disputes, or out-of-state assets extend the timeline.
The process:
- Petition filed with Superior Court (or informal application)
- Personal representative appointed
- Assets inventoried
- Creditors notified; 4-month claims period
- Debts paid, taxes handled
- Assets distributed per intestacy law
- Closing statement filed
Informal vs. formal probate: Arizona’s UPC allows for “informal probate” — a faster, less court-supervised version for non-contested estates. Formal probate involves more court hearings. Most intestate estates start informally but can be pushed to formal proceedings if disputes arise.
Cost: Arizona probate typically costs 3–5% of the estate. For a $400,000 estate, that’s $12,000–$20,000 in attorney fees, court costs, and administrative expenses. Court filing fees are a few hundred dollars; the real cost is professional time.
Arizona-Specific Quirks
Community property state — same complexity as other CP states. What did you own before the marriage? What did you inherit? What did you buy with mixed funds? These questions get complicated fast, especially in long marriages or second marriages. Without a will, the court works through these categorizations — sometimes getting them wrong, always taking time.
No estate or inheritance tax. Arizona has neither a state estate tax nor an inheritance tax. Whatever probate costs in fees, you won’t lose additional money to Arizona death taxes. This makes Arizona genuinely tax-friendly for estates.
Small estate affidavit — actually useful in Arizona:
- Personal property under $75,000: Heirs can use a simple affidavit to collect assets without probate, waiting 30 days after death.
- Real property under $100,000: A simplified “Affidavit of Succession” can transfer real estate without full probate, waiting 6 months after death.
These thresholds are higher than most states, and they cover real property — which is unusual. For smaller estates, Arizona actually offers a meaningful escape from full probate. But with Maricopa County home prices pushing $400,000–$600,000 for starter homes, most Arizona homeowners still blow past these thresholds.
Uniform Probate Code benefits: Arizona’s adoption of the UPC means the process is more standardized and somewhat less arcane than states with older, more complicated probate laws. The informal probate track is genuinely faster. This is a real advantage if you’re stuck in probate — but it’s still not as good as having a will.
Strong spousal protections. Arizona’s community property regime, combined with UPC spousal protections, means surviving spouses are generally well-protected. But “generally well-protected” breaks down immediately in blended families, where prior-relationship children split separate property and the formula creates conflict.
How to Avoid This Mess
Arizona’s probate laws are more modern than most. That’s genuinely true. But “modern” doesn’t mean “good for your family.” It just means the bureaucracy is slightly more organized.
A will still lets you:
- Control who gets your separate property (without the prior-children split)
- Protect an unmarried partner
- Name guardians for your kids
- Keep more assets out of probate with proper titling guidance
- Choose your own personal representative
Arizona’s small estate thresholds help if your estate is small. Most people’s estates are not small. A $69 will at Killswitch is cheaper than one hour of a probate attorney’s time and covers you in all 50 states.

Frequently Asked Questions
Q: Is Arizona a community property state?
Yes. Property acquired during the marriage is community property — owned 50/50 by both spouses. Property owned before marriage, or received as a gift or inheritance during marriage, is separate property. These categories are treated differently under intestacy law.
Q: Does Arizona have a small estate process that skips probate?
Yes — one of the more generous in the country. Personal property under $75,000 can be collected by affidavit 30 days after death. Real property under $100,000 can be transferred by affidavit after 6 months. If your estate fits these limits, you may avoid full probate entirely.
Q: Does Arizona have a state estate tax or inheritance tax?
No. Arizona has neither. Your estate won’t owe Arizona any death taxes, regardless of size. This is a genuine advantage over neighboring California or states like Oregon.
Q: What happens to my live-in partner if I die without a will in Arizona?
Nothing. Arizona doesn’t recognize common-law marriage. An unmarried, unregistered partner inherits nothing under intestacy. A will is the only protection for an unmarried partner.
Q: How long does probate take in Arizona?
Simple estates under Arizona’s informal UPC process can take 6–9 months. The 4-month creditor claims period sets the minimum. Complex estates, real estate issues, or disputes among heirs extend this to 12+ months.
