How to Defend a Partition Action When a Co‑Tenant Seeks to Force Sale of an Inherited Arizona Home

Short answer: Don’t ignore the complaint. In Arizona a co‑tenant can generally ask the court to partition (divide or sell) jointly owned real property. Your best defenses are procedural (timely answer, challenge standing or service), factual (showing different ownership or a prior transfer), and equitable (ask for credit for mortgage, taxes, improvements, or propose a buy‑out or partition in kind). Gather paperwork, consider negotiation or mediation, and consult a lawyer quickly because partition cases move on a court calendar and a default can end your options.

Why this happens and the legal background

When an inherited house is titled in more than one person (for example, heirs holding as tenants in common), any co‑owner may file a civil action asking the court to partition the property rather than continue joint ownership. Arizona law provides procedures for partition actions in the civil statutes and the probate code governs how the house became jointly held after a death. For the statutory framework, see Arizona Revised Statutes, Title 12 (civil actions) and Title 14 (probate and estates):
A.R.S. Title 12 — Courts and Civil Proceedings and
A.R.S. Title 14 — Trusts, Probate and Fiduciaries.

Detailed answer — step‑by‑step defense options under Arizona law

1. Immediate procedural steps (do these first)

Read the court papers and note the response deadline. In Arizona, you must file a written answer or appropriate motion by the deadline shown on the summons or you risk default.
Preserve the property. Do not remove fixtures, start demolition, or transfer title without court permission. That can hurt your case and create claims for damages.
Collect key documents immediately: deed(s), the will or probate order that transferred the property, title insurance, mortgage statements, tax bills, receipts for major improvements, insurance policies, and any agreements among heirs about use or sale.

2. Procedural and jurisdictional defenses

Service and standing: challenge defective service of process or the plaintiff’s standing if they no longer own an interest. If the plaintiff was not properly served, the court may dismiss or require re‑service.
Prior adjudication: if a court has already decided ownership or partition in a separate case, you can assert claim preclusion (res judicata) or collateral estoppel.

3. Factual and equitable defenses

Arizona courts will apply equitable principles in partition actions. Common defenses and counterclaims include:

Ownership disputes: show that title did not vest as the plaintiff claims (e.g., probate order or deed that contradicts the plaintiff’s assertion).
Accounting and credits: ask the court to account for contributions. If you paid mortgage, taxes, insurance, or made improvements, you can seek credit against the proceeds or ask that the court adjust shares. Document all payments and improvements—receipts, cancelled checks, bank records and tax records help.
Waiver or agreement: if heirs previously agreed in writing (or in some cases by long‑standing conduct) to different terms (for example, buyout or deferred sale), you can enforce that agreement instead of allowing a forced sale.
Partition in kind: for some properties a court may divide land instead of ordering sale. For houses on a single lot, physical division is often impractical, but you can argue division is possible or that sale is inequitable.
Equitable defenses: laches (unreasonable delay), unclean hands, or other equitable defenses may apply depending on the facts—e.g., if the plaintiff tried to conceal facts or acted unfairly.

4. Practical tactical options

Negotiate a buyout: propose that one co‑tenant buy the other’s share. This is often quickest and least costly.
Propose mediation or settlement: Arizona courts encourage resolution. Mediation can preserve value and relationships while avoiding litigation costs.
Request an appraisal: contest the plaintiff’s valuation with your own licensed appraiser to ensure a fair sale price if sale is ordered.
Ask for a crediting hearing: ask the court to recognize expenses paid by co‑tenants (mortgage, taxes, utilities, improvements) before dividing sale proceeds.
Move for a temporary restraining order or injunction (rare): if an immediate sale is imminent and would cause irreparable harm, you may ask the court to pause sale activities while the litigation proceeds. This is fact‑specific and requires strong proof.

5. If the court orders sale

If the court concludes the property must be sold, Arizona courts typically order a public sale and then divide net proceeds among owners after credits for debts and allowable costs. You should be prepared to:

Challenge the sale procedures (notice, appraisal, method of sale) if they are flawed.
Seek credits for amounts you paid that benefited the property (mortgage payments, taxes, repairs).
Ask the court to delay sale to allow a co‑tenant time to arrange financing to buy out others.

Typical timeline and costs

Partition actions in Arizona can take several months to more than a year, depending on complexity, contested issues, the court’s docket, and whether the parties settle. Litigation costs include filing fees, attorney fees (usually borne by each side unless the court orders otherwise), appraisals, and possibly real estate sale expenses. Negotiation or mediation is often less expensive and faster.

When to get a lawyer

Hire counsel immediately if the plaintiff moves quickly or if title, probate, or large sums are at stake.
Consider at least a consultation if the matter appears resolvable by buyout or if you need help documenting credits and preparing an accounting.
Ask a prospective attorney about experience with Arizona partition and probate issues, fee structure, and likely timelines.

Helpful Hints

Do not ignore the summons. Missing a response deadline can result in a default judgment that strips you of protections.
Document everything now—payments, improvements, insurance, repairs, and any written agreements among heirs. Digital photos and dated receipts are valuable evidence.
Keep the property insured and current on mortgage and tax payments if you are able; falling behind weakens your position and increases costs to be recouped.
Consider a licensed appraiser early so you can make informed buyout or settlement offers based on market value.
Explore mediation before escalation—courts and lawyers often recommend mediation in partition disputes.
Ask about seeking credits for mortgage/tax payments and improvements—courts can adjust distributions to reflect unequal contributions.
If the property passed through probate, obtain a copy of the probate order or guardianship documents; those records affect who the court treats as owner.
Be realistic about costs: a forced sale can reduce net proceeds due to legal and sale expenses; sometimes a negotiated sale or buyout produces more money for everyone.

Resources and statutes

For the statutory framework consult Arizona Revised Statutes, Title 12 (civil actions including partition procedures) and Title 14 (probate and estate rules that often govern inherited property):
A.R.S. Title 12 and
A.R.S. Title 14.
