Summary: If you co-own real estate in Arizona and the owners can’t agree on what to do with it, a partition action under A.R.S. §§ 12-1211 through 12-1225 lets a court divide the property or order it sold. Here is who can file, what the complaint has to include, and how the case moves forward.
Co-owning property works well until it doesn’t. Siblings inherit a house and one wants to sell while another wants to move in. Unmarried partners split up and still share a mortgage. Business partners hold a rental together and stop agreeing on anything. In Arizona, when co-owners hit a deadlock, the law’s main remedy is a partition action.
1. Who Can File a Partition Action in Arizona?
Under A.R.S. § 12-1211(A), anyone who owns or claims real property, or any interest in it, can ask the court to divide it among all the owners and claimants. That usually includes:
- Tenants in common (for example, siblings who inherited a home together)
- Joint tenants with right of survivorship. Filing a partition action effectively ends the survivorship feature.
- Unmarried co-owners, such as former partners or friends who bought together
- Business partners or investors who hold title in their own names
Arizona courts generally treat partition as a matter of right for a co-owner. You usually don’t have to show that the other owner did anything wrong. The main exception is when the owners signed an agreement giving up or limiting that right, such as a co-ownership agreement or an operating agreement.
A note on married couples: Property a married couple holds as community property is normally divided in a divorce under Title 25, not in a partition action.
2. Where to File
You file the complaint in the superior court of the county where the property, or any part of it, is located (A.R.S. § 12-1211(A)). A Scottsdale house goes to Maricopa County Superior Court, and a cabin in Payson goes to Gila County.
3. What the Complaint Must Include
Under A.R.S. § 12-1211(B), a partition complaint must state:
- The names and residences of every owner and claimant, if known
- The share or interest the plaintiff and each other owner holds or claims, as far as the plaintiff knows
- A description of the property that identifies it, along with its estimated value
Getting the parties right matters. Every person with an ownership interest has to be named and served. Many practitioners also name lienholders, such as mortgage lenders, so the judgment binds everyone with a stake in the title.
Unknown Owners
If an undivided interest belongs to someone the plaintiff can’t identify, A.R.S. § 12-1212 allows service by publication. The plaintiff files an affidavit, and the summons runs in a newspaper in that county for four weeks in a row. The court’s final decree must protect the unknown owner’s rights.
Abstract of Title
Under A.R.S. § 12-1214, a plaintiff can get an abstract of title before filing and note in the complaint where the other parties can inspect it. Whoever pays for a reasonably necessary abstract can recover that cost, plus interest.
4. The Court Decides Who Owns What
At the hearing, the court determines each party’s share of the property and settles any disputes over title (A.R.S. § 12-1213). Contested cases often turn on unequal down payments, mortgage and tax payments, improvements, and whether one owner has lived in the property alone. In equity, the court can account for these when it divides the property or the sale proceeds.
5. Partition “In Kind” vs. Partition by Sale
Arizona law offers two outcomes.
Partition in Kind (Physical Division)
If the property can be fairly divided, the court enters a judgment saying how it will be split and appoints at least three impartial commissioners to do it, with a surveyor if needed (A.R.S. § 12-1215). Under § 12-1216, the commissioners divide the land into shares that are about equal in value relative to each owner’s interest, taking location, size and benefits into account. They then assign the shares by lot.
The commissioners file a sworn written report describing each parcel, its estimated value and who receives it (§ 12-1217). Any party can object. If the report is materially wrong or unfair, the court must reject it and appoint new commissioners (§ 12-1219). Once the court confirms the report, each party owns their parcel with the same effect as a warranty deed (§ 12-1221).
Partition by Sale
Physical division rarely makes sense for a single-family home or a condo. Under A.R.S. § 12-1218(B), if a fair division would reduce the property’s value, or if a sale would be more beneficial to the parties, the court orders the property sold. The Arizona Supreme Court has held (Bledsoe v. Hood) that when a sale is proper under § 12-1218(B), the court doesn’t have to go through the in-kind commissioner process first.
The court appoints a commissioner to run the sale on the terms and with the notice it sets. The proceeds come back to the court, which distributes them according to each owner’s interest (§ 12-1218(C)). A buyer who has the deed can get a writ of assistance to take possession (§ 12-1218(D)).
6. Who Pays the Costs?
Under A.R.S. § 12-1225, the commissioners and surveyor are paid a reasonable daily rate. Those fees are taxed as costs of the action and divided among the parties in proportion to the value of the share each receives. Attorney’s fees are a separate question that depends on the facts and on any agreements between the owners, so talk to counsel early.
7. Practical Steps Before You File
- Pull a title report to confirm exactly how title is held and who holds liens.
- Gather payment records for the down payment, mortgage, taxes, insurance and improvements.
- Check for a co-ownership agreement that might limit or waive partition.
- Consider recording a lis pendens (notice of pending action) so buyers and lenders know about the case.
- Try a negotiated buyout first. Many partition cases settle once the other side sees the court will order a sale anyway.
