Do All Heirs Have to Agree to Sell in California?
Justin Borges, DRE #01940318 · 8 min read
No. In California, if one or more heirs want to sell an inherited house and another heir refuses, the heirs who want to sell can file a partition action in court to force the sale. Unanimous agreement makes the process faster and cheaper, but it is not legally required to sell co-owned inherited property.
What You Will Learn
How Heirs Actually Own an Inherited House
When two or more people inherit a house together, whether through a will, intestate succession, or a trust distribution, California law treats them as tenants in common by default unless the estate plan says otherwise (CA Probate Code §21102). The mechanics of this ownership form and what happens when co-owners disagree are covered in detail by the California Courts Self-Help Center (probate). Each heir owns an undivided fractional interest in the whole property. Two siblings inheriting equally each own an undivided 50% interest, not a specific half of the house.
This ownership structure is the reason the "all heirs must agree" assumption is so common, and so wrong. Under tenancy in common, every co-owner has an independent right to sell, transfer, or force the sale of their share, regardless of what the other co-owners want. No single heir can hold the property hostage simply by refusing to sign, and no single heir can be forced to stay a co-owner indefinitely against their will either.
In my work with families across Pasadena, Glendale, and greater LA County, this is usually the first thing I clarify when three or four siblings inherit a parents' home and immediately disagree about what to do with it. The law does not require consensus. It requires a process, and that process exists specifically because families do not always agree.
Heirs almost always assume a holdout sibling can block a sale forever. In California, that is simply not how tenancy in common works. Disagreement changes the path to a sale, not whether a sale can happen.
Justin Borges, CA DRE #01940318When Unanimous Consent Is Actually Required
There are situations where practical unanimity matters even though it is not strictly a legal requirement to force a sale. Understanding the difference helps set realistic expectations before a disagreement escalates.
During active probate administration
If the estate has not yet closed probate and title has not been distributed to the heirs individually, the executor or administrator, not the heirs directly, generally controls the sale process (Courts.ca.gov). Under California's Independent Administration of Estates Act, an executor with full authority can typically sell without a court hearing, while an executor with limited authority (or none granted by the will) must get probate court confirmation of the sale first. The California Courts Self-Help Center outlines the full probate administration process and when court approval is required. Either way, heirs disputing a sale during this phase are really disputing the executor's decision or petitioning the probate court, not exercising a direct veto themselves.
When the property sits in a trust with co-trustees
If the house is held in a living trust with multiple co-trustees, the trust document itself controls how decisions get made. Some trusts require unanimous trustee consent for a sale; others allow majority rule. This is a matter of trust drafting, not a general rule for inherited property, and it needs to be read directly rather than assumed.
When a lender or title company requires all signatures
Once title has distributed to the heirs as tenants in common, a title company will not close escrow without every titled owner's signature on the deed and closing documents, even though any one owner could force the underlying sale through a partition action if the others refuse to cooperate voluntarily. This is a practical closing requirement, not a legal veto power.
Outside of these specific situations, once heirs hold title as tenants in common, no individual heir can permanently block the others from selling their interests or forcing a sale of the whole property through the courts.

A partition action is a lawsuit, governed in California by Code of Civil Procedure Section 872.010 and following sections (CA Civil Code), that any co-owner of real property can file when co-owners cannot agree on what to do with it. License and legal standing of the agent facilitating the sale can be verified through the California Department of Real Estate. Under Code of Civil Procedure Section 872.710(b), partition is available as of right unless barred by a valid waiver, and California courts have long treated this right as close to absolute, allowing only narrow exceptions such as an enforceable written agreement not to partition for a defined period, or a co-ownership agreement that already spells out a buyout process the parties must follow first.
Once filed, the court has two basic options: partition in kind (physically dividing the property, which is almost never practical for a single-family home) or partition by sale (ordering the property sold, with proceeds divided among the co-owners according to their ownership percentage). For a house, partition by sale is the outcome in the overwhelming majority of cases.
What the process typically looks like
- An heir who wants to sell files a partition action naming all other co-owners
- The court determines each party's ownership percentage and whether any credits or offsets apply (for example, one heir paid the property taxes or insurance while others did not)
- The court appoints a referee to oversee marketing and sale of the property if the parties cannot agree on process
- The property sells, typically through a standard listing and sale process, and proceeds are distributed according to ownership share after costs and any court-ordered adjustments
Partition actions are slower and more expensive than a voluntary sale. Property tax reassessment implications from transferring inherited property are governed under Proposition 19 (LA County Assessor) and can meaningfully affect what each heir walks away with. They typically add months to the timeline and generate legal fees that reduce everyone's proceeds. Courts also have discretion to award attorney's fees and costs from the sale proceeds, which can meaningfully shrink what each heir walks away with. This is precisely why most real estate attorneys, and most agents who work probate and trust sales regularly, treat partition as a last resort rather than a first move.
What Does a Los Angeles Partition Case Actually Look Like?
Here is a simplified version of a scenario I see regularly in Los Angeles County: three siblings inherit a parents' home in the San Gabriel Valley. Two want to sell and move on. One wants to keep the house and rent it out. No trust language or executor authority resolves the disagreement, and title has already distributed to all three as tenants in common.
Voluntary Sale (What Happens If All Three Agree)
Contested Partition Action (What Happens If One Refuses)
In practice, once the holdout heir understands that a partition action almost always ends in a court-ordered sale anyway, just slower and more expensive, most disputes settle well before trial. The threat of partition tends to bring reluctant co-owners to the negotiating table faster than any amount of family pressure.
How Can California Co-Heirs Avoid a Partition Lawsuit?
Filing a lawsuit against your own sibling is rarely anyone's first choice, and it is usually not necessary. Before heading to a partition action, most families I work with in Los Angeles County have real alternatives worth exploring first.
Options If You Want to Sell
Options If You Want to Keep It
A buyout is often the cleanest solution: one or more heirs who want to keep the property pay the departing heirs' fair market share, typically based on a professional appraisal or a comparative market analysis of the home's current value (C.A.R.). Current median home values for Los Angeles County are published monthly by the California Association of Realtors and also tracked by the Zillow home values index. This requires the buying heir to qualify for financing or have cash available, but it avoids litigation entirely and usually closes faster than a contested court process.
If you are navigating a disagreement like this with siblings or other co-heirs, getting an accurate, defensible valuation of the property early is often the single most useful step, since disagreements about value are just as common as disagreements about whether to sell at all.

Frequently Asked Questions
Do all heirs have to agree before an inherited house can be sold in California?
No. Heirs who co-own inherited property as tenants in common can force a sale through a court partition action even if one or more co-owners refuse to agree, though unanimous agreement makes the process faster and cheaper.
What is a partition action in California?
A partition action is a lawsuit under Code of Civil Procedure Section 872.010 that any co-owner of real property can file to force a sale (or, rarely, a physical division) when co-owners cannot agree on what to do with the property.
Can one sibling block the sale of an inherited house forever?
Generally no. Once title has distributed to heirs as tenants in common, any co-owner can file a partition action, and California courts treat the right to partition as close to absolute except in narrow, specific circumstances.
How long does a partition action take in California?
Contested partition actions commonly take 6 to 18 months or longer depending on county caseload and whether the parties settle, compared to 45 to 60 days for a voluntary sale agreed to by all heirs.
Can a holdout heir be bought out instead of going to court?
Yes. Heirs who want to keep the property can buy out the shares of heirs who want to sell, typically based on a professional appraisal or valuation, which avoids litigation and usually closes faster than a partition action.
Does probate change who can force a sale?
Yes. During active probate, the executor or administrator generally controls the sale process (Probate Code §10500 et seq.), sometimes subject to court approval, rather than the heirs acting directly. Once probate closes and title distributes to heirs, tenancy-in-common rules apply.
Is a partition action the same for a house held in a trust?
Not necessarily. A trust document may specify how co-trustees make sale decisions, including whether unanimous consent is required. Trust terms control in that situation and should be reviewed directly rather than assumed.
