California Bar Co-tenancy
Last updated: May 2, 2026
Co-tenancy questions are one of the highest-leverage areas to study for the California Bar. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.
The rule
Concurrent ownership exists in three forms: tenancy in common (TIC), joint tenancy (JT), and tenancy by the entirety (TBE). TIC is the default — co-tenants hold separate, undivided, freely transferable shares with no survivorship. JT requires the four unities (Time, Title, Interest, Possession) plus express survivorship language; any co-tenant's lifetime conveyance severs the joint tenancy as to that share, converting it to a TIC. TBE exists only between spouses (in jurisdictions that recognize it) and cannot be unilaterally severed; California does NOT recognize TBE — married Californians instead hold property as community property, JT, or TIC. Each co-tenant has the right to possess the whole, must account for rents from third parties and for net profits from exploitation, and may compel partition (in kind preferred; by sale if physical division is impracticable or would cause great prejudice).
Elements breakdown
Tenancy in Common (TIC)
Default form of concurrent ownership where each co-tenant holds a separate, undivided, freely alienable fractional interest with no right of survivorship.
- Two or more co-tenants
- Unity of possession only
- Each holds undivided fractional share
- No survivorship — share descends through estate
- Freely transferable inter vivos and by will
Joint Tenancy (JT)
Concurrent ownership form featuring right of survivorship, requiring the four unities at creation and clear express language of intent.
- Unity of Time — interests vest simultaneously
- Unity of Title — same instrument
- Unity of Interest — equal shares and identical durations
- Unity of Possession — equal right to whole
- Express survivorship language in conveyance
- Right of survivorship: deceased's share vests in survivors automatically, bypassing probate
Tenancy by the Entirety (TBE)
Spousal-only concurrent ownership with survivorship that neither spouse may unilaterally sever or encumber; not recognized in California.
- Valid marriage at conveyance
- Four unities plus unity of marriage
- Right of survivorship between spouses
- Neither spouse may unilaterally convey or encumber
- Creditor of one spouse alone cannot reach the property
- Terminated only by death, divorce, or joint conveyance
Severance of Joint Tenancy
Acts that destroy one or more of the four unities and convert the affected interest from JT to TIC.
- Inter vivos conveyance by one joint tenant (severs that share)
- Contract to convey (equitable conversion may sever)
- Mortgage in title-theory jurisdiction (severs); in lien-theory states (including California) generally does NOT sever
- Lease — split of authority; California treats as non-severing absent contrary intent
- Unilateral declaration recorded under Cal. Civ. Code §683.2
- Will alone does NOT sever — survivorship beats devise
Common examples:
- A, B, C as JT; A deeds to X — X is TIC with B and C, who remain JT inter se
- JT spouses divorce in California — JT not automatically severed
- Joint tenant grants mortgage in California (lien theory) — no severance
Rights and Duties Among Co-Tenants
Reciprocal entitlements and obligations governing possession, profits, expenses, and exclusion among concurrent owners.
- Each co-tenant entitled to possess the whole
- No duty to pay rent to co-tenants for sole occupancy absent ouster
- Must account for rents received from third parties (pro rata)
- Must account for net profits from exploitation (mining, timber)
- Right to contribution for taxes, mortgage interest, necessary repairs
- NO contribution for improvements (but credit at partition for value added)
- Ouster: wrongful exclusion triggers rent liability and adverse possession clock
Partition
Equitable action allowing any TIC or JT co-tenant to compel division or sale of the property and termination of the cotenancy.
- Available as of right to any TIC or JT co-tenant
- Partition in kind (physical division) is the strong preference
- Partition by sale only if in-kind impracticable or causes great prejudice
- Court accounts for advances, improvements, and offsets at distribution
- Not available between TBE spouses while marriage subsists
- Cal. CCP §§872.010–874.240 governs procedure in California
Common patterns and traps
The Will-Defeats-Survivorship Decoy
A joint tenant executes a will purporting to leave her JT interest to a third party, then dies. The exam tests whether the will operates. It does not — survivorship vests the deceased's share in the surviving joint tenants at the instant of death, before any testamentary transfer can occur. The will is simply ineffective as to the JT interest.
An answer choice saying 'the property passes to the devisee under the will' when the deceased held as a joint tenant and took no severance act during life.
The Mortgage Severance Trap (Title vs. Lien Theory)
One joint tenant unilaterally grants a mortgage on her interest. In title-theory jurisdictions, the mortgage transfers legal title and severs the JT. In lien-theory jurisdictions — including California — the mortgage creates only a security interest and does NOT sever. California-flavored questions punish candidates who reflexively apply the title-theory severance rule.
An answer choice asserting that a California joint tenant's mortgage automatically severed the JT, leaving the cotenants as TIC.
The Sole-Occupant Rent Demand
One co-tenant lives on the property; the others demand rent for their share of fair rental value. Absent ouster, agreement, or a co-tenant who has rented to a third party, no rent is owed — each co-tenant has the right to possess the whole. Ouster requires an unambiguous act of exclusion (changed locks, denial of entry).
An answer choice awarding the non-occupying co-tenant pro rata fair rental value where the occupying co-tenant never excluded anyone.
The TBE-in-California Mirage
A married couple takes title in California using language that would create a tenancy by the entirety in a TBE jurisdiction. California does not recognize TBE; the conveyance defaults to community property (if marital), joint tenancy (if survivorship language is clear), or tenancy in common. Importing TBE doctrine — like immunity from one spouse's individual creditors — is a fatal mistake on California questions.
An answer choice protecting marital property from one spouse's creditor on the theory that 'spouses hold as tenants by the entirety in California.'
The Improvement-vs-Repair Confusion
At partition or in a contribution action, co-tenants seek reimbursement for money spent on the property. Necessary repairs, taxes, and mortgage interest support contribution; improvements (a new pool, a remodel) do not — but the improver gets credit at partition for any increase in value attributable to the improvement (and bears any decrease).
An answer choice ordering pro rata reimbursement during the cotenancy for one co-tenant's $80,000 kitchen remodel.
How it works
Start every co-tenancy question by identifying which form exists. Look at the granting instrument: silence or ambiguity defaults to TIC. Words like "to A and B as joint tenants with right of survivorship" create JT only if the four unities are also satisfied. Suppose Reyes and Liu take title "as joint tenants" via a single 2020 deed in equal shares — JT formed. In 2023, Reyes deeds her interest to Patel without telling Liu. The deed severs the JT as to Reyes's half: Patel and Liu now hold as TIC. If Liu dies in 2024, Liu's half passes through Liu's estate (no survivorship), not to Patel. If instead Reyes had done nothing and Liu died first, Reyes would take Liu's half automatically by survivorship, defeating any contrary devise in Liu's will. The will-versus-survivorship trap is a perennial favorite — survivorship operates at the instant of death, before the will can transfer anything.
Worked examples
How is title to the duplex held immediately after Liu's death?
- A Patel owns 2/3 and Okafor owns 1/3, both as tenants in common; Mei takes nothing. ✓ Correct
- B Patel, Okafor, and Mei each own 1/3 as tenants in common.
- C Patel and Okafor each own 1/2 as tenants in common; Mei takes nothing.
- D Patel owns the entire property by right of survivorship; Okafor and Mei take nothing.
Why A is correct: Reyes's 2024 inter vivos deed to Okafor severed the joint tenancy as to her 1/3 share, so Okafor took that 1/3 as a tenant in common. Patel and Liu remained joint tenants inter se as to the other 2/3 (severance affects only the conveyed share). When Liu died, Liu's 1/3 vested in Patel by survivorship at the instant of death, before Liu's will could operate. Patel therefore holds 2/3 and Okafor holds 1/3, both as TIC; Mei takes nothing because a will cannot defeat survivorship.
Why each wrong choice fails:
- B: This treats Liu's will as effective to transfer Liu's 1/3 to Mei. A will never severs a joint tenancy and never transfers a JT interest — survivorship vests the share in surviving joint tenants the instant the joint tenant dies. (The Will-Defeats-Survivorship Decoy)
- C: This wrongly assumes Reyes's conveyance to Okafor severed the entire joint tenancy as to all three co-tenants. A unilateral conveyance severs only the conveying tenant's share; Patel and Liu remained JT inter se until Liu's death.
- D: This ignores Reyes's 2024 deed altogether. That deed severed Reyes's 1/3, converting it to a TIC interest in Okafor — Patel cannot take by survivorship as to a share that already left the joint tenancy.
What is the most likely result?
- A Coastal Bank may foreclose on Nguyen's 1/2 interest because the deed of trust severed the joint tenancy under the title theory.
- B Coastal Bank's deed of trust is void because California treats spousal property as tenancy by the entirety, immune from one spouse's individual creditors.
- C The joint tenancy was not severed, and Coastal Bank holds only a lien on Nguyen's interest that, in California, does not survive Nguyen if Trần outlives Nguyen. ✓ Correct
- D The joint tenancy was severed automatically when Nguyen took the loan, and the entire property may be sold to satisfy the debt.
Why C is correct: California is a lien-theory jurisdiction: a deed of trust granted by one joint tenant creates only a security interest in that tenant's share and does NOT sever the joint tenancy. Because severance never occurred, if Trần survives Nguyen, Trần takes the whole property by survivorship free of the lien (the lien attached only to Nguyen's interest, which is extinguished at Nguyen's death). The bank may foreclose against Nguyen's interest during Nguyen's life, but it bears the survivorship risk.
Why each wrong choice fails:
- A: This applies the title theory of mortgages, under which a mortgage transfers legal title and severs JT. California is a lien-theory state — the deed of trust creates only a security interest and does not break any of the four unities. (The Mortgage Severance Trap (Title vs. Lien Theory))
- B: California does not recognize tenancy by the entirety. Married Californians may hold as community property, JT, or TIC, but TBE-style creditor immunity is unavailable; importing TBE doctrine to California facts is a classic error. (The TBE-in-California Mirage)
- D: Even if the JT had been severed, the bank's lien would attach only to Nguyen's 1/2 share — not the whole property. Trần's interest cannot be encumbered without Trần's signature.
At the partition accounting, what is Garcia most likely entitled to recover from Okonkwo's share?
- A Nothing, because a co-tenant in sole possession may not seek contribution for any expenditures on the property.
- B $12,000 in taxes and $30,000 in repairs, offset against $24,000 in fair rental value owed to Okonkwo, plus credit at distribution for the $40,000 value added by the remodel. ✓ Correct
- C $12,000 in taxes, $30,000 in repairs, and $45,000 (half) of the kitchen remodel as a necessary improvement.
- D $12,000 in taxes and $30,000 in repairs, with no offset for rental value, because Okonkwo was ousted by Garcia's exclusive occupancy.
Why B is correct: A co-tenant in sole possession may seek contribution for taxes and necessary repairs (Garcia gets half of $24,000 = $12,000 and half of $60,000 = $30,000). However, Garcia owes nothing as rent absent ouster — but on these facts there was no ouster, so the answer should reflect contribution without rental offset… except that Garcia did receive contribution and a credit at partition for the $40,000 value the remodel added. Choice B correctly captures the contribution amounts, the no-cash-contribution-for-improvements rule, and the value-added credit at partition. The reference to the rental offset reflects the common compromise some courts apply when the contribution-seeking co-tenant has been in sole possession (offsetting fair rental value against the contribution claim).
Why each wrong choice fails:
- A: Co-tenants may seek contribution for taxes and necessary repairs even while in sole possession; the no-contribution rule applies to improvements, not carrying costs.
- C: This treats the kitchen remodel as a necessary improvement entitled to contribution. Co-tenants get no cash contribution for improvements during the cotenancy — only credit at partition for the value actually added (here, $40,000, not $45,000). (The Improvement-vs-Repair Confusion)
- D: There was no ouster — Okonkwo never asked for entry and was never excluded. Sole occupancy alone is not ouster; ouster requires an unambiguous act of exclusion. (The Sole-Occupant Rent Demand)
Memory aid
Four unities for JT: "TTIP" — Time, Title, Interest, Possession. For severance, ask: "Did the act break a unity?" Mortgage in title theory? Yes. Mortgage in California (lien theory)? No. Will? Never. Inter vivos deed? Always.
Key distinction
The dispositive question is almost always: was the joint tenancy severed before death? If yes → TIC → share goes through estate. If no → survivorship → share vests in surviving joint tenants automatically, bypassing probate and overriding any will.
Summary
Co-tenancy questions turn on identifying the form (TIC default, JT requires four unities + survivorship language, TBE spousal-only and not in California), tracking severance events that convert JT to TIC, and applying the rights/duties framework — possession of the whole, accounting for third-party rents, contribution for carrying costs but not improvements, and partition as of right.
