An undivided share is not a physical slice of the house
Maya can own 70% and Luis 30% as tenants in common while each has a right to possess the whole property, subject to agreements and the rights of the other owner. Neither owns a particular bedroom merely because the ownership percentages differ. Income, expenses, and sale proceeds raise share-allocation questions; possession raises a different question.
At a tenant in common's death, the interest generally passes through that owner's estate or other applicable estate arrangement, not automatically to the other co-owner. A deed naming two owners does not by itself create joint tenancy. Read the vesting language.
Survivorship depends on the form and whether it remains intact
Joint tenancy must be expressly created in the manner allowed by Civil Code section 683. If an unsevered joint tenant dies, the surviving joint tenant or tenants take the deceased owner's interest by survivorship. This is different from inheriting the interest under a will.
A lifetime transfer or another legally effective severance can change that outcome. California's statutory severance rules include formal and recording requirements in particular circumstances. Do not assume an unsigned intention to sever, or a clause in a will alone, defeats survivorship.
Community property is not just another name for joint tenancy
Family Code section 760 generally treats property acquired during marriage while domiciled in California as community property, subject to exceptions. Acquisition date, source of funds, valid agreements, and applicable presumptions matter. Separate property does not become community property merely because its owner marries.
Civil Code section 682.1 permits spouses to hold community property with right of survivorship using the required express declaration. Distinguish ordinary community property, this survivorship form, joint tenancy, and separate property. Selecting vesting also has estate and tax consequences that require advice about the actual facts, not a universal recommendation from an exam-prep lesson.
Apply it, then change one fact
Maya and Luis, unrelated owners, hold title as tenants in common: Maya 70%, Luis 30%. Maya dies. Does Luis automatically own the whole property?
Reasoning: No. Tenancy in common does not supply automatic survivorship. Maya's interest passes under the applicable estate arrangements. Luis's existing 30% interest remains his.
Change one fact: If the deed instead expressly created joint tenancy and it remained unsevered at Maya's death, survivorship would change the result. Marriage alone would not make these unrelated owners community-property holders.
Keep these distinctions clear
- Tenancy in common
- Unequal undivided shares are possible; no automatic survivorship.
- Joint tenancy
- Express creation and survivorship; check for effective severance.
- Community property
- Marital-property classification; distinguish ordinary and survivorship forms.

Frequently asked questions
Can California tenants in common own unequal shares?
Yes. The shares are undivided interests in the property, not exclusive ownership of particular rooms or physical sections.
Does naming two owners on a deed create survivorship?
Not necessarily. Identify the actual vesting form, its express language, and any legally effective changes. Tenancy in common has no automatic survivorship.
