Partition: the option of last resort, and why knowing about it helps

When co-owners of an inherited property truly cannot agree, California law gives any co-owner the right to force a resolution through a partition action — a lawsuit that ends, for a house, almost always in a court-ordered sale and division of proceeds.

California's Partition of Real Property Act (for inherited co-owned property) added protections: the court gets an independent appraisal, and co-owners who want to keep the property get a right to buy out the sibling who filed, at appraised value, before any forced sale.

Why this matters even if nobody sues: it defines the walls of the room. A sibling refusing every option isn't actually holding all the cards — any co-owner can start a process that ends in a sale at market value with lawyers taking a slice. Reasonable people who understand that usually negotiate. The buyout right also means 'I'll force a sale' isn't all-powerful either.

It is genuinely a last resort: slow, expensive, and hard on families. Its best use is as shared knowledge that makes the voluntary deal happen.
