If you are dealing with the Maricopa County probate court, someone you love has probably just died. This page collects the practical facts - locations, fees, forms, timelines, and the free help the court itself offers - in one place, in plain language.

What filing costs
The court's fee to open an informal probate (or file transfer affidavits) is $306, per the Clerk of Superior Court's fee schedule. That is only the court's fee - attorney fees, appraisals, and publication costs come on top and are usually far larger. Our probate cost calculator puts a realistic total range on it in about a minute.
Do you actually need probate?
Maybe not. Arizona lets smaller estates skip full probate using transfer affidavits when the estate holds no more than $200,000 in personal property and $300,000 in Arizona real estate (values after liens, under A.R.S. § 14-3971 - these limits were raised substantially in 2025, so older articles citing lower numbers are out of date). Assets with named beneficiaries, joint ownership with survivorship rights, or a beneficiary deed skip probate entirely regardless of size.
Informal vs. formal probate
Most Maricopa County probates are informal: there is an original will (or clear heirs), nobody is contesting anything, and a court registrar can appoint the personal representative without hearings. Formal probate - with a judge and hearings - becomes necessary when the will is contested, the original is missing, or the family disagrees. Informal is dramatically cheaper and faster, which is one more reason families in conflict pay so much more.
The forms
The court publishes free, fill-in-the-blank packets through its Law Library Resource Center - the probate forms library covers informal probate, small-estate affidavits, and personal representative duties. The informal probate packet is the one most families start with.
How long it takes
Plan on 6 to 12 months for a typical uncontested estate. Arizona law gives creditors 4 months from first notice to file claims, so no estate closes faster than that. Contested estates commonly run a year or more.
Free help the court offers
