Concurrent ownership exists when more than one person possesses ownership rights in the same property at the same time. The subject is deceptively simple. Students may assume that if two people own land together, each person merely owns a particular percentage of the physical property. But concurrent ownership does not usually work that way. A cotenant may own only a fractional interest while still possessing a legal right to use and possess the entire parcel.
Concurrent ownership problems repeatedly raise questions concerning possession, transfer, survivorship, rent, expenses, improvements, ouster, creditors, and partition. A strong examination answer should identify the form of concurrent ownership first and then analyze the rights and obligations that follow from that classification.
The principal concurrent estates are:
- Tenancy in common.
- Joint tenancy.
- Tenancy by the entirety.
Each form answers important questions differently. Can an owner transfer an interest? Does the interest pass by will? Is there a right of survivorship? Can one owner sever the relationship? What happens when one owner occupies the land alone? What happens when one owner pays all the taxes or makes expensive improvements? Can one owner force a sale?
The central lesson is that concurrent ownership divides ownership interests without necessarily dividing possession.
I Tenancy in Common
A tenancy in common is the modern default form of concurrent ownership.
Each tenant in common has:
- A separate fractional ownership interest.
- An equal right to possess the whole property.
- No right of survivorship.
The ownership shares may be equal or unequal.
Suppose A owns seventy percent of Blackacre and B owns thirty percent. A owns a larger economic share, but A does not automatically possess seventy percent of the land while B possesses thirty percent. Both ordinarily possess a right to use and occupy the entire property, subject to the equal possessory rights of the other.
This point is critical because students often confuse the size of an ownership interest with the size of a possessory right.
A tenant in common may transfer the tenant’s fractional interest during life. The interest may also pass by will or by intestate succession. The transferee or successor ordinarily becomes a tenant in common with the remaining owners. Thus, a tenancy in common does not depend on the continued identity of the original cotenants.
Hypothetical
"O conveys Blackacre to A and B as tenants in common. A owns a seventy-five-percent interest and B owns a twenty-five-percent interest. A begins living in the house on Blackacre. B later announces that B also intends to move into the house. A refuses, arguing that A owns three-fourths of the property and therefore has the right to occupy the house alone."
A’s argument misunderstands concurrent possession. Although A owns the larger fractional interest, B ordinarily has an equal right to possess the entire parcel. Ownership percentage affects matters such as division of proceeds and expenses, but it does not automatically divide the physical property into separate possessory zones.
Exam Tip
When a problem gives ownership percentages, do not assume those percentages control possession. Separate the questions: What percentage does each cotenant own? vs. What right does each cotenant have to possess the property? A smaller fractional owner may still have the right to possess the entire parcel.
II Joint Tenancy
A joint tenancy is distinguished from a tenancy in common primarily by the right of survivorship.
When one joint tenant dies, that tenant’s interest ordinarily disappears and the surviving joint tenant or tenants continue to own the property. The deceased joint tenant’s interest does not ordinarily pass through the deceased tenant’s will. This makes survivorship the defining feature of the joint tenancy.
Suppose A and B own Blackacre as joint tenants with right of survivorship. If A dies first, B ordinarily becomes the sole owner. A cannot normally defeat B’s survivorship merely by writing a will that leaves A’s share to C.
The reason is structural. At A’s death, the joint-tenancy interest does not ordinarily become part of A’s probate estate. It disappears through the operation of survivorship.
III. Creation of a Joint Tenancy
Traditional common law required four unities for creation of a joint tenancy:
Time
Acquire at the same time.
Title
Acquire by same instrument.
Interest
Equal size and duration.
Possession
Equal right to possess.
Modern statutes may relax these technical requirements. Nevertheless, the traditional four-unities framework remains important for understanding the doctrine.
Modern courts also often prefer a tenancy in common when the instrument is ambiguous. For that reason, clear survivorship language is generally important.
Risky: “To A and B.” (Likely creates a tenancy in common under modern defaults).
Common Trap
Do not assume that multiple owners automatically hold as joint tenants. Joint tenancy requires survivorship. If the instrument is ambiguous and the applicable law favors tenancy in common, the absence of clear survivorship language may matter.
IV. Severance of a Joint Tenancy
A joint tenant may ordinarily sever the joint tenancy by transferring that tenant’s interest.
Suppose A and B are joint tenants. A transfers A’s interest to C. C and B ordinarily become tenants in common with respect to their shares. A’s transfer destroys the survivorship relationship between A and B because A is no longer an owner.
The analysis becomes more interesting when there are more than two joint tenants.
Severance Hypothetical
"A, B, and C own Blackacre as joint tenants with right of survivorship. A sells A’s one-third interest to D."
D ordinarily holds a one-third tenancy-in-common interest. B and C may remain joint tenants with one another as to the remaining two-thirds interest.
If B later dies, C may acquire B’s share by survivorship, while D continues to own D’s one-third tenancy-in-common interest.
This illustrates why concurrent-ownership problems should be diagrammed carefully. The form of ownership may differ among the various shares. Severance need not destroy the joint tenancy completely; it may sever only the transferred share.
V. Mortgages and Severance
Whether a mortgage severs a joint tenancy may depend on the jurisdiction’s treatment of mortgages.
Title Theory
A mortgage may be treated as transferring sufficient title to the mortgagee to sever the joint tenancy.
Lien Theory
The mortgage is treated primarily as a lien on the mortgagor’s interest and ordinarily does not sever the joint tenancy.
This distinction can create an important examination problem when the mortgaging joint tenant dies before foreclosure. Suppose A and B own Blackacre as joint tenants. A mortgages A’s interest to Bank and later dies.
If the mortgage did not sever the joint tenancy (lien theory), A's interest disappears at death, and B takes the property free and clear of the Bank's mortgage. If the mortgage did sever the joint tenancy (title theory), A and B became tenants in common, and A's encumbered share passes to A's heirs, subject to the mortgage.
Exam Tip
When a joint tenant mortgages an interest, ask two separate questions: 1. Does the jurisdiction follow lien theory or title theory? 2. Did the mortgage sever the joint tenancy? Do not assume that every mortgage has the same effect on survivorship.
VI Tenancy by the Entirety
A tenancy by the entirety is a specialized form of concurrent ownership available to married spouses in some jurisdictions.
Typical characteristics include:
- A right of survivorship.
- Equal possessory rights.
- Limited unilateral severance.
- Protection from certain individual creditors.
Where the traditional form applies, neither spouse may ordinarily destroy the other spouse’s survivorship right acting alone.
This feature sharply distinguishes tenancy by the entirety from joint tenancy. A joint tenant may generally sever by transferring that tenant’s share. A spouse holding property by the entirety traditionally has much less unilateral power to destroy the estate. Divorce commonly converts the estate into a tenancy in common unless applicable law or agreement provides otherwise.
Common Trap
Do not treat tenancy by the entirety as merely a joint tenancy involving married people. It traditionally includes stronger limits on unilateral severance and may provide protections against certain individual creditors.
VII Equal Right to Possession
Every cotenant generally possesses a right to use and possess the whole property. This principle applies even when the ownership percentages are unequal.
A cotenant who owns ninety percent does not automatically receive ninety percent of the bedrooms, ninety percent of the acreage, or the unilateral right to decide where the ten-percent owner may enter. Possession is concurrent rather than physically divided.
This is one of the most important conceptual distinctions in the subject. A cotenant’s fractional share describes the ownership interest, but cotenants ordinarily share possession of the whole. The practical consequence is that one cotenant cannot ordinarily exclude another cotenant merely because the first owns a larger share.
VIII. Ouster
An ouster occurs when one cotenant wrongfully excludes another from possession. Mere exclusive occupancy ordinarily is not enough.
Suppose A and B own a house as tenants in common. A lives in the house while B chooses to live elsewhere. A’s occupation alone ordinarily does not establish ouster because A has a legal right to possess the property.
Ouster generally requires conduct clearly inconsistent with the other cotenant’s rights, such as:
- Denial of access (changing locks).
- A claim of exclusive ownership.
- Refusal after a demand for possession.
- Other conduct clearly repudiating the cotenancy.
The basic question is whether the occupying cotenant is merely exercising a shared possessory right or has instead repudiated the other cotenant’s equal right to possession. Ouster can have significant legal consequences. It may create liability for rent, support an ejectment or partition claim, and eventually become relevant to adverse-possession analysis.
IX. Rent Owed by a Cotenant in Possession
A cotenant who occupies common property ordinarily does not owe rent to a nonoccupying cotenant merely because the occupying cotenant uses the premises alone.
The reason follows directly from the right-to-possession principle. The occupying cotenant is exercising a lawful possessory right.
Rent may become payable when:
- There has been an ouster.
- The cotenants agreed that rent would be paid.
- A statute provides otherwise.
Accordingly, students should not automatically calculate rent merely because one owner occupies the property while the other does not. The first question is whether the nonoccupying cotenant has been wrongfully excluded.
Common Trap
Exclusive occupancy is not the same as ouster. One cotenant may live alone on commonly owned property without owing rent if the other cotenants remain legally free to possess the land.
X. Rent Received from Third Parties
The rule changes when a cotenant receives rental income from a third party.
A cotenant who rents all or part of the common property to a third person generally must account to the other cotenants for their proportionate shares of net rental income.
Suppose A and B own Blackacre equally. A rents the property to Tenant for $2,000 per month. A ordinarily cannot keep the entire rental stream. B generally has a right to B’s proportionate share of the net income.
This creates an important distinction:
Occupying cotenant personally uses property → generally no rent owed absent ouster.
Cotenant receives rent from third party → generally must account to other cotenants.
XI Taxes, Mortgages, and Necessary Expenses
Concurrent ownership also creates questions about who must pay the costs of preserving the property. A cotenant who pays more than that cotenant’s proportionate share of necessary carrying expenses may seek contribution from the other cotenants.
Possible expenses include:
- Property taxes
- Mortgage principal/interest
- Necessary insurance
- Essential repairs
The basic idea is that costs necessary to preserve common property may fairly be shared among those who own it. Students should distinguish these necessary expenses from voluntary improvements. That distinction determines whether contribution is ordinarily available.
XII. Repairs
A cotenant may generally obtain contribution for necessary repairs after proper notice to the other cotenants, depending on the governing law.
Necessary Preservation
Designed to prevent deterioration or maintain existing property (e.g., repairing a badly leaking roof). Contribution is more likely.
Optional Enhancement
Designed to make the property more valuable or attractive (e.g., replacing a functioning roof with ornamental tile). Treated as an improvement.
The classification matters because cotenants generally have stronger claims for contribution for necessary expenses than for voluntary improvements.
XIII. Improvements
A cotenant ordinarily cannot make voluntary improvements and then force the other cotenants to reimburse their proportional shares. The rule protects each owner from having another cotenant unilaterally choose expensive enhancements and impose those costs on everyone else.
However, improvements may still matter later during partition, accounting, or sale.
An improving cotenant may receive credit for the increase in property value attributable to the improvement, rather than automatically recovering the amount spent.
Suppose A spends $60,000 improving jointly owned land, but the improvement increases the property’s market value by only $35,000. The relevant credit may be based on the $35,000 increase in value rather than A’s entire expenditure. Conversely, if the improvement reduces the property’s value, the improving cotenant may bear the loss.
Exam Tip
Do not equate the cost of an improvement with the credit available for the improvement. Emphasize the increase in value attributable to the improvement rather than automatic reimbursement of the amount spent.
XIV. Waste Among Cotenants
A cotenant may be liable for waste that harms common property. The right to possess the whole property does not create a right to destroy or substantially impair the property for the other owners.
Thus, concurrent possession is broad but not unlimited. A cotenant who damages structures, removes resources in a destructive manner, or otherwise substantially harms common property may face liability to the other cotenants.
This principle reconciles two ideas: Every cotenant has the right to possess the whole property, but no cotenant has the right to use that possession to destroy the co-owners’ interests.
XV Partition
A major feature of concurrent ownership is the ability of a cotenant ordinarily to seek partition. Partition ends the unwanted concurrent relationship by dividing the property or its value.
XVI. Partition in Kind
Physically divides the property into separate parcels. Historically, this remedy was preferred when physical division was practicable.
E.g., Dividing a 100-acre uniform tract into separate parcels so each owner retains real property rather than money.
Not always practical for a single house or small urban parcel.
XVII. Partition by Sale
The property is sold and the proceeds are divided among the cotenants after appropriate accounting.
Appropriate when:
- Physical division is impracticable.
- Division would substantially reduce value.
- Sale better protects the owners' interests.
XVIII. Agreements Restricting Partition
Because partition may disrupt shared ownership arrangements, cotenants sometimes agree not to seek partition.
Such agreements may be enforceable when they restrict partition for a reasonable period or serve a legitimate purpose. An unlimited prohibition, however, may be invalid as an unreasonable restraint on alienation.
The analysis involves balancing the parties’ contractual arrangement against the law’s general reluctance to lock owners indefinitely into unwanted concurrent ownership.
XIX. Adverse Possession by One Cotenant Against Another
Adverse possession between cotenants presents a special difficulty. Because each cotenant has a lawful right to possess the whole property, ordinary exclusive occupation is not hostile to the rights of the other cotenants.
To claim adversely against another cotenant, the occupying cotenant generally must establish a clear ouster or repudiation of the others’ rights, followed by possession for the required statutory period.
This makes adverse possession against a fellow cotenant more difficult than adverse possession against a stranger. When a stranger occupies land, possession is obviously inconsistent with the owner’s rights. When a cotenant occupies common property, that possession begins as legally permissible.
Common Trap
Do not begin the adverse-possession clock merely because one cotenant occupies the property alone. Exclusive possession is ordinarily consistent with concurrent ownership. Look for ouster before treating possession as hostile.
XX. Accounting Among Cotenants
Concurrent-ownership disputes often require an accounting. A useful approach separates four categories:
- 1. Income: Did one cotenant receive rents from third parties? Other cotenants are entitled to their proportionate shares of net income.
- 2. Necessary Expenses: Did one cotenant pay taxes, mortgages, or necessary repair costs beyond their share? Contribution may be available.
- 3. Improvements: Did a cotenant voluntarily improve the property? Automatic contribution is unavailable, though value added may be credited during partition.
- 4. Occupancy: Did one cotenant occupy the property personally? No rent is owed merely for exclusive occupancy unless there was ouster or agreement.
XXI. Complete Examination Framework
When confronted with a concurrent-ownership problem, proceed systematically:
1. Identify the Concurrent Estate: TIC, JT, or TBE? Do not analyze survivorship until classified.
2. Identify Each Share: Unequal shares do not create unequal possessory rights.
3. Analyze Possession: Has each been allowed to possess the whole? If excluded, analyze ouster.
4. Analyze Transfer & Survivorship: Does survivorship exist? Did a transfer or mortgage sever the JT?
5. Financial Rights: Separate 3rd party rents, occupancy, taxes, repairs, and improvements.
6. Ouster & Adverse Possession: Has one affirmatively denied the rights of another to start the AP clock?
7. Partition: In kind or by sale?
8. Mortgages/Creditors: Lien theory vs. Title theory?
Exam Tip: Concurrent-ownership essays become much easier when students keep six concepts separate: Ownership percentage, Possessory rights, Income rights, Expense obligations, Survivorship, and Transfer. A problem may involve all six, but each must be analyzed independently.
Chapter Summary
Concurrent ownership divides ownership interests without necessarily dividing possession. The three principal forms are tenancy in common, joint tenancy, and tenancy by the entirety.
A tenancy in common is the default. Each cotenant owns a separate fractional interest, possesses an equal right to use the whole property, and has no survivorship right.
A joint tenancy includes a right of survivorship. Traditional law required the unities of time, title, interest, and possession. A joint tenant may ordinarily sever the joint tenancy by transferring their interest. Mortgage severance depends on whether the jurisdiction follows title theory (severs) or lien theory (does not sever).
A tenancy by the entirety is available to married spouses and typically includes survivorship, equal possession, restricted unilateral severance, and protection from some individual creditors.
All cotenants have an equal right to possess the whole property. Ouster occurs when one cotenant wrongfully excludes another. Mere exclusive occupancy is insufficient. Ouster may affect rent liability, partition, and adverse possession.
A cotenant in personal possession does not owe rent to nonoccupying cotenants absent ouster or agreement. A cotenant receiving rental income from third parties must account for the other owners’ proportionate shares.
Necessary expenses (taxes, mortgage, essential repairs) may support contribution. Voluntary improvements ordinarily do not, although the increase in property value attributable to the improvement may be credited during partition.
A cotenant may seek partition to end the relationship. Partition in kind physically divides the property. Partition by sale converts the property into proceeds when physical division is impracticable.
Adverse possession between cotenants is difficult because possession is initially lawful. Clear ouster or repudiation is required before possession becomes hostile.
