Equitable Title and Constructive Trust Claims: Partition When You Are Not on the Deed

A person does not need to be named on the recorded deed to seek partition of California real property. California courts have long held that "the owner of an equitable title is the owner of real property, and may maintain an action to establish his equitable right, and in the same action obtain a partition" (Crowley v. Crowley (1903) 140 Cal. 141, 145), and that in a partition action "the parties may assert any title which they have, legal or equitable" (Luco v. De Toro (1891) 91 Cal. 405).

Why this comes up so often between unmarried couples and family members

Real property is regularly purchased or improved with money from someone whose name never made it onto the deed, an unmarried partner who contributed to the down payment, an adult child who paid for renovations to a parent’s home expecting an ownership share, or a family member who was told they would be added to title and never were. When that relationship breaks down or the record owner dies, the person left off the deed may still have an enforceable ownership claim.

The presumption favors record title, and what overcomes it

Evidence Code § 662 creates a presumption that the person holding recorded legal title also holds the beneficial interest in the property, and that presumption can only be rebutted by clear and convincing evidence. Overcoming it typically requires establishing a recognized legal basis for the equitable claim, a contract, an agreement to hold title for another’s benefit, a resulting trust, or a constructive trust, not simply that the claimant contributed money or lived at the property.

Constructive and resulting trust theories

A resulting trust arises by operation of law under Civil Code § 853 when one party pays for property but title is taken in another’s name, based on the presumed intent of the parties. A constructive trust, codified at Civil Code §§ 2223 and 2224, is an equitable remedy imposed to prevent unjust enrichment, typically where the record owner acquired or is retaining the property through wrongful conduct. Because both are involuntary trusts imposed by a court rather than created by contract, they are exempt from the Statute of Frauds and require no writing to enforce (Martin v. Kehl (1983) 145 Cal.App.3d 228, 238).

How this interacts with a partition action

A person asserting equitable title typically needs the court to recognize that interest, often through a quiet title claim brought alongside the partition case, before or as part of obtaining partition. Once that equitable interest is established, the claimant is treated as a tenant in common for partition purposes and can seek partition on the same footing as a co-owner named on the deed.

Frequently asked questions

I paid part of the down payment on my ex-partner’s house, but I’m not on the deed, do I have any rights?

Possibly, depending on the facts, contributing money toward a purchase does not automatically create an ownership interest, but it can support a resulting trust or constructive trust claim if the evidence shows the parties intended you to have a beneficial interest despite not being on title.

What kind of evidence matters most in an equitable title dispute?

Documentary evidence tends to matter most, bank records showing the source and amount of contributed funds, written communications discussing the ownership arrangement, and any documentation of an agreement, express or implied, about who was meant to hold an interest in the property.

Is a constructive trust claim the same as a partition action?

No, a constructive trust or resulting trust claim establishes that a claimant has an equitable ownership interest in the property in the first place; partition is the separate process, available once ownership is established, for dividing or selling the property among the co-owners.
