A partition action is a court proceeding used to address jointly owned property when co-owners cannot agree on its division or sale. It can involve physical division, sale, valuation, accounting, or other court-supervised relief.

Partition disputes may arise between:
- Unmarried former partners
- Siblings
- Heirs
- Friends
- Investors
- Business associates
- Other co-owners
Divorcing spouses often address property in family court, although legal counsel should determine the proper forum and remedy.
What can make partition expensive?
Costs may include:
- Attorney fees
- Court filings
- Appraisals
- Referee expenses
- Broker fees
- Property maintenance
- Accounting
- Delays
- Disputed reimbursements
Frequently Asked Questions
Can one owner force a sale?
Partition rights and defenses depend on ownership, agreements, statutes, and case facts. No outcome should be assumed.
Will the court divide proceeds equally?
Not necessarily. Ownership interests, credits, expenses, offsets, and legal findings may affect allocation.
Can mediation avoid partition litigation?
It may help parties reach a buyout or voluntary sale.
Educational information
Partition is litigation and requires advice from a qualified California attorney.
Compare a negotiated sale or buyout with the time, cost, and uncertainty of litigation.
