Can You Force a Property Sale When Your Co-Owner Refuses to Agree in Richmond?
The Short Answer
Yes, you can technically sell a property you co-own without the other owner’s signature — but only through a court-ordered partition action, not a standard sale. In California, any co-owner has the right to force a sale or division of jointly held property, regardless of what the other owners want. The process takes time and legal work, but it is a real option.
How a Partition Action Actually Works in California
A partition action is a lawsuit filed in civil court that asks a judge to either physically divide a property or order it sold and split the proceeds. California’s Partition of Real Property Act, which was updated in 2023, changed some of the ground rules — especially for inherited properties held by multiple heirs.
Partition in Kind vs. Partition by Sale
Courts first ask whether the property can be fairly divided into separate parcels. A large rural tract might be split down the middle. A single-family home in a residential neighborhood almost certainly cannot. When physical division isn’t practical, the court orders a partition by sale: the property goes on the market, and the net proceeds are distributed among the co-owners based on their ownership shares.
One important detail many people miss: if you’ve been paying the mortgage, property taxes, or made significant improvements while the other co-owner hasn’t, the court can adjust the distribution to reflect those unequal contributions. You don’t necessarily walk away with just your percentage of the sale price.
What the Timeline Looks Like
Filing the lawsuit is the starting point, not the finish line. Most partition cases in California take anywhere from six months to over two years, depending on whether the other co-owner contests the action, whether an appraisal is disputed, or whether the court needs to sort out ownership credits and offsets. In Richmond and the surrounding Contra Costa County area, court backlogs can add time to that estimate. The sooner you get proper legal guidance, the better you can plan around those delays.
When This Situation Comes Up Most Often
Most people dealing with a stuck co-ownership situation fall into a few common categories:
Inherited Property With Multiple Heirs
One sibling wants to sell the family home; another wants to keep it. This is one of the most common triggers for a partition lawsuit. The 2023 updates to California law actually added a right of first purchase for co-owners in these cases — meaning a co-owner can buy out the others at fair market value before a forced sale happens. A real estate attorney can walk you through whether that option applies and how to use it strategically.

Relationships and Business Partnerships That End
Two people buy a property together as partners, friends, or former romantic partners. One wants out; the other won’t budge. A partition by sale is often the only realistic path when negotiation fails. Courts don’t require both parties to agree — they just require one co-owner to formally ask.
If you’re at that impasse right now, this breakdown of legal options for California property owners covers what comes next in plain terms.
Residents across the Richmond area, from Point Richmond to the Iron Triangle, often find that having an attorney evaluate the ownership structure early prevents much bigger disputes later.

California’s partition rules are also shaped by the California Code of Civil Procedure, starting at Section 872.010, which governs how courts manage these cases from start to finish.

Related Questions
Can a co-owner be forced to sell their share even if they live in the property?
Yes. In California, living in the property does not protect a co-owner from a partition action. The occupying co-owner may receive a credit for improvements or be charged for the fair rental value of their exclusive use during the time they lived there, but the court can still order a sale. Courts do weigh hardship factors, but residency alone is not enough to block the action.
Does a co-owner need a lawyer to file a partition lawsuit, or can they do it themselves?
Technically, a co-owner can file a partition lawsuit without an attorney, but it is rarely a good idea. Partition cases involve property appraisals, title history, contribution credits, and sometimes contested ownership percentages. Missing a procedural step or failing to account for offsets can cost you money at distribution. Most people find that hiring a real estate litigation attorney saves more than it costs, especially when the property is worth a meaningful amount.
