Clear and convincing evidence is a higher standard of proof than preponderance of the evidence, and California Evidence Code section 662 requires it before a court will disregard how a deed holds title. In a partition action, that difference often decides who owns what share of the property and which money claims succeed.
A co-owner who asks for reimbursement generally faces the ordinary standard, while a co-owner who claims that record title does not reflect true ownership faces the higher one.
California Evidence Code Section 662 Presumes the Deed Reflects True Ownership
California Evidence Code section 662 presumes that the owner of legal title also owns the full beneficial title. Although it is not one of the California partition statutes, it applies whenever a partition action raises a dispute over who really owns the property. The statute provides:
“The owner of the legal title to property is presumed to be the owner of the full beneficial title. This presumption may be rebutted only by clear and convincing proof.”
California Evidence Code section 662
Legal title is what the recorded deed says, while equitable title describes who actually holds the benefits of ownership. Section 662 creates a presumption affecting the burden of proof, so under California Evidence Code section 606 the co-owner who challenges the deed must prove that the record owner is not the full beneficial owner.
Preponderance of the Evidence Is the Ordinary Standard for Accounting Claims in a Partition Action
Under California Evidence Code section 115, the burden of proof requires proof by a preponderance of the evidence unless the law provides otherwise. California’s civil jury instructions describe that standard as persuading the fact finder that something is more likely true than not true.
The ordinary standard governs most claims in the partition offsets and accounting that California Code of Civil Procedure section 872.140 authorizes, because California law does not set a higher standard for them. Typical claims include:
- Mortgage payments that a co-owner paid beyond that co-owner’s share
- Property taxes and insurance that a co-owner covered alone
- Money spent on repairs and improvements
- The rental value owed by a co-owner who excluded the others
Clear and Convincing Evidence Requires More Than a Preponderance of the Evidence
California’s civil jury instructions explain that clear and convincing evidence is a higher burden of proof than preponderance of the evidence. Preponderance asks whether a fact is more likely true than not true, while clear and convincing evidence asks whether the fact is highly probable.
A story that is merely believable usually is not enough. Documents created at the time of purchase, such as a signed agreement or written messages, generally carry more weight than later recollections. Courts and attorneys may call a claim of ownership contrary to the deed a quiet title action or a claim of equitable ownership.
How Evidence Code Section 662 Affects Ownership Disputes in a California Partition Action
A partition court resolves ownership before it divides anything. Under California Code of Civil Procedure section 872.620, the court ascertains the state of the title upon adequate proof when that is necessary to grant relief, and under California Code of Civil Procedure section 872.720 the interlocutory judgment of partition must determine the interests of the parties in the property.
The Court of Appeal confirmed that requirement in Summers v. Superior Court (2018) 24 Cal.App.5th 138, 143. When a deed to tenants in common does not state each owner’s share, courts generally presume equal shares, and a co-owner who claims a different share must overcome that presumption with clear and convincing proof.
Courts apply the same standard to claims based on unwritten agreements. In Tannehill v. Finch (1986) 188 Cal.App.3d 224, 228, the Court of Appeal held that a claimant seeking a 50 percent interest in property based on an implied agreement was required to establish the claim by clear and convincing evidence. Spoken promises about real property also run into the statute of frauds in California real estate.
Unequal down payments show why the distinction matters. A co-owner who paid more can seek reimbursement through the accounting, or can try to prove a larger ownership share, but only the second path requires clear and convincing proof. The same is true when a defendant claims that a co-owner was only a cosigner added to the deed to obtain a loan.
These disputes arise between siblings, business partners, and former romantic partners who bought together, and the last group often asks how to get an ex-partner off the deed. Married couples follow different presumptions under the California Family Code, so this article addresses co-owners who are not spouses.
Protect Your Ownership Interest in a California Partition Action
The deed is the starting point for every ownership dispute, and a co-owner who wants to change it must carry the heavier burden. Knowing which standard governs each claim lets a co-owner decide whether to contest the deed or to seek reimbursement through the accounting.
Ownership questions can be tried in the same case, because the rights determinable in a partition action include title disputes as well as the sale and the accounting.
