Can I force the sale or division of inherited property when a co‑owner won’t cooperate?

Short answer: Under California law you can file a civil partition action in superior court to force a physical division (partition in kind) or sell the property and divide the proceeds (partition by sale) when a co‑owner refuses to cooperate. This article explains the practical steps, courtroom process, likely outcomes, and what documents and facts you will need to proceed.

Detailed Answer — Step‑by‑step guide under California law

1. Confirm ownership and your legal interest

Before filing, establish how title is held. Common situations after someone dies:

You own an interest as a tenant in common under the deed (common with inherited real property).
Title may still be in the decedent’s name if the estate has not been probated; ownership may not have passed yet.
The property could be held in trust, with ownership controlled by the trust terms.

Gather: the deed, death certificate, will or trust documents, any probate filings, the preliminary title report (or county recorder search), mortgage and lien statements, property tax bills, and any written communications with the co‑owner.

2. Try to resolve it without court (demand, negotiation, buyout)

Court is costly and slow. Typical pre‑filing steps:

Send a written demand for partition or request to buy your interest (keep a copy).
Propose alternatives: sell on the open market and split proceeds, one owner buys out the other, or use mediation.
Obtain informal valuations or a broker opinion so offers are realistic.

If these fail, you can move forward with filing a partition action in superior court.

3. File a complaint for partition in the Superior Court where the property is located

Required basics of the complaint:

Identify the property with the legal description (from the deed or title report).
Name all co‑owners and all persons with recorded liens or possible interests (mortgagees, judgment creditors, trustees, adult devisees, guardians for minors, etc.). California partition law requires joining everyone with an interest in the property so the court can determine rights and divide proceeds. See California Code of Civil Procedure for parties and procedures: CCP § 872.010 and related sections.
Allege how each party holds an interest (for example, “tenant in common — 50% interest inherited from decedent”); explain attempts to resolve and why partition is necessary.
Pray for relief: partition in kind (divide the land) or partition by sale and an accounting for liens, taxes, and costs.

Filing triggers the court process. You must pay filing fees (or request a fee waiver if eligible).

4. Serve the complaint on all defendants and interested parties

After filing, you must serve the complaint and summons on every named party following the California Code of Civil Procedure rules. If a party is unknown or at an unknown address, the court may permit substituted service or service by publication in limited circumstances.

5. The court process — temporary orders, discovery, and appointed officers

Early steps in court:

Temporary orders: you can ask for temporary restraining orders or injunctions to prevent waste, demolition, transfer, or major encumbrances on the property while the case proceeds.
Discovery: you can obtain records about title, expenses, improvements, and payments. Expect depositions, document requests, and interrogatories.
Appointment of referee/commissioner: under the partition statutes, the court often appoints a referee or commissioner to value the property, recommend division in kind if feasible, or oversee the sale. See CCP § 873.010 (appointment of commissioners) and related provisions for procedure.

6. Partition in kind vs. partition by sale

The typical outcomes:

Partition in kind — physical division: The court will order division only when the property can be fairly divided without substantial prejudice to owners. Factors: parcel shape, size, improvements, and feasibility.
Partition by sale — sale and split of proceeds: If division is impractical or would substantially reduce value (for example, a house on a single lot that cannot be divided), the court will order a sale and distribute net proceeds after liens and costs.

The court balances equitable considerations and will account for liens, outstanding mortgages, unpaid taxes, and contributions by parties (improvements or payments). See the general partition procedures and distribution rules in the California partition statutes; for sample commissioner procedures see CCP § 873.520 regarding commissioners’ reports and related provisions.

7. Distribution, credits, and costs

When proceeds are distributed, the court will:

Pay senior liens and mortgages first (enforced by sale proceeds).
Reimburse parties who paid taxes, mortgage payments, or made improvements that preserved or enhanced value — often via equitable credits or offsets in the accounting.
Deduct court costs, commissioner fees, auction or broker commissions, and reasonable attorney fees if statutory or contractual grounds exist.

8. Potential outcomes and timing

Partition actions can take many months to over a year depending on complexity, contested issues, and court schedules. Expect costs for filing, service, appraisals, a referee/commissioner, and legal fees if you hire counsel.

9. Special considerations when property is part of a probate or trust

If title has not been transferred yet because of ongoing probate or trust administration, you may need to address those proceedings first or join the personal representative or trustee as a party. Partition actions often intersect with probate and trust administration; consult a probate attorney if the estate or trust is unresolved.

Helpful Hints

Collect key documents before filing: deed(s), will/trust, probate filings, death certificate, recent title report, mortgage and lien records, property tax statements, insurance policies, and receipts for repairs or improvements.
Get a title search or preliminary title report to identify all recorded interests (lenders, judgments, easements).
Obtain one or more appraisals early to understand fair market value and to support a buyout offer or damages calculations.
Consider mediation or a buyout proposal: courts often encourage settlement; a neutral mediator or a formal buyout can be far cheaper than litigation.
If a co‑owner is preventing sale, you can seek temporary injunctive relief to preserve value (stop demolition, eviction, or transfer) while the case proceeds.
If a co‑owner is a minor, incapacitated, or unknown, the court will require special steps (guardian ad litem, conservator, or substituted service). Make sure to name all possible interested parties in the complaint.
Keep records of any payments you make (mortgage, taxes, maintenance). The court will consider contributions when allocating proceeds.
Expect costs: commissioner fees, appraisal costs, escrow/sale costs, title insurance updates, and attorney fees if you hire counsel.
Use the California partition statutes as a starting point for procedure and requirements: see the Code of Civil Procedure, Partition (Commencing at CCP § 872.010): California Code of Civil Procedure — Partition (CCP §§ 872.010 & following).

When to hire an attorney

Consider hiring a California real property or probate lawyer if:

The other owner adamantly refuses to cooperate or threatens action that destroys value.
Title issues exist (deed errors, unclear inheritance, conflicting documents).
There are multiple liens, judgments, or a mortgage in default.
There are minors, incapacitated persons, or unknown heirs involved.
You need help with the court process, discovery, or a contested valuation.

Partition cases involve technical pleadings, joined parties, and procedural steps. A lawyer can prepare the complaint, represent you at hearings, and manage valuation/commissioner processes.

Example (hypothetical)

Suppose you inherited a one‑half interest in a house when your parent died. Your sibling inherits the other half but refuses to sign a sale. You first send a written demand offering to buy or sell. Your sibling refuses. You file a partition action in the county superior court where the house sits, naming your sibling and the mortgage holder as defendants. The court appoints a commissioner, obtains appraisals, finds physical division impractical (a single house on one parcel), orders a sale, pays the mortgage and sale expenses, and distributes the net proceeds 50/50 after crediting one sibling for recent mortgage payments made on behalf of the property.

Final advice

Filing a partition action is often the right tool when a co‑owner refuses to cooperate, but it has costs and risks. Start by collecting documents, making a written demand, getting an appraisal, and discussing options with a California real property attorney or mediator. If you proceed, be prepared to join all interested parties, follow court procedures, and possibly accept a sale rather than a physical split.
