Yours, Mine and Ours

Yes, it’s true. More than one person can own the same property…even at the same time. It could be real estate, a car or an investment account among other things. But this is something most of us are already aware of. Most of us are familiar with joint ownership arrangements. However, the ways in which multiple people may each have an interest in the same property are many and varied.

Joint ownership arrangements are just one form of concurrent property ownership – where more than one person has an ownership interest in the same property at the same time. In New York for example, the Estates, Powers and Trusts Law (EPTL) also discusses tenancy in common and tenancy by the entirety as concurrent interests¹. These arrangements are distinguished from sole ownership (estate in severalty) when considering the number of people owning an interest in the same piece of property². Finally, community property may also be considered to be a form of concurrent ownership³.

The basic types of concurrent ownership

Joint and survivorship titling (JTWROS):
“Two or more parties have equal rights and ownership of an account or real estate⁴.” If one of the owners dies, the decedent’s ownership interest automatically transfers to the survivors⁵. For JTWROS to validly exist, the “Four Unities” must be satisfied:

Unity of Time
Unity of Title
Unity of Interest
Unity of Possession

Essentially, each joint tenant must take title at the same time, through the same instrument in equal amounts, each with an equal legal right to enjoy the entire property^5,6.

During the lives of the joint tenants, each has access to the property, and each can make contributions or withdrawals. On the death of a joint tenant, transfer of ownership to surviving joint tenants is automatic, avoiding a probate proceeding. However, with access to the whole property, any joint tenant might decide to “access” more than their pro rata share. Additionally, especially where the joint tenant is not a spouse, there is the specter of a potential gift tax⁷.

What if the creation of the arrangement doesn’t specify it is a joint tenancy with the right of survivorship? It might then depend on state law. For example, NY EPTL §6-2.2(a) provides “A disposition of property to two or more persons creates in them a tenancy in common, unless expressly declared to be a joint tenancy.”

Tenancy in common (TIC):
A TIC differs from the JTWROS in that there is no survivorship feature, the shares in the property may be unequal in size and each share may pass pursuant to each owner’s individual estate plan on their death. However, all of the owners still have the right to enjoy the entire property⁸.

An advantage of TIC ownership is that each owner has a separate interest in the property which can be sold, gifted or bequeathed without consent of the other owners. Its flexibility makes it an option for business oriented arrangements⁹. However, under some circumstances, its advantages may become disadvantages. Without the survivorship feature, a decedent owner’s share does not transfer automatically, and a probate proceeding may be required as a result⁹.

Tenancy by the entirety:
Tenancy by the entirety is a form of concurrent joint and survivor ownership between individuals who are married at the time they take title to the property. In the event of a divorce, the parties become tenants in common. It is not available in all states. Some states may permit the arrangement for domestic partners. Some states may permit the arrangement only for real estate while others may not so limit it¹⁰.

Tenancy by the entirety may offer some limited creditor protection from satisfaction of a debt or judgment against one of the spouses. However, there is no additional protection from debts shared by both spouses¹¹.

Community property:
Generally, community property refers to any real or personal property acquired by either spouse during the marriage and such property is essentially deemed to be owned equally by both spouses. Nine states have community property laws, but they are not all the same. Each state may have different rules regarding measuring and dealing with community property upon the death of one of the spouses¹². Special planning problems may exist with “migratory couples” moving between community property states and non-community property states¹³.

Other types of “SHARED” ownership interests

In addition to the forms of concurrent property ownership discussed above where multiple people have an ownership interest in the same property at the same time, it is possible that the interests of two or more people in the same property may exist for different periods of time, or at different times or with other limitations. Some common types of arrangements are discussed below.

Present and future interests:
Some ownership interests may not exist until the passage of an amount of time or the occurrence of a future event. A familiar type of future interest arrangement is the life estate where, for example, the current owner of a home (the present interest) may remain in the property until death when another specified person will succeed to ownership (the future interest)¹⁴.

Just considering real estate, transfer on death deeds¹⁵, lady bird deeds¹⁶ and usufructs¹⁷ are alternative types of arrangements that may create a future interest upon the death of a present interest owner. Each arrangement has different rules and are available in different states.

Vested and contingent interests:
A vested interest in property is a present, enforceable entitlement to that property. A contingent interest is one that may happen depending on the occurrence (or sometimes non-occurrence) of a future event¹⁸.

For example, your father’s Will provides that you inherit $1,000,000 at age 25. Your interest in the $1,000,000 is contingent on you reaching 25 years of age, at which time the interest may vest as you become entitled to it. However, you (or your heirs) may have no entitlement to the $1,000,000 if you do not reach age 25.

Limitations of an ownership interest:
An ownership interest may be subject to the rights of others only partially or temporarily.

For example, you may own some land subject to an easement which may allow another person (or persons) to access your land for a specific purpose, such as to access their property as may be the case with common driveways¹⁹.

In contrast to the concept of a life estate discussed above, ownership of property may transfer to another only for a period of time upon the current owner’s death, after which time it may vest elsewhere.

In summary, there are many ways that more than one person can have an interest in the same property, sometimes at the same time. Each of these different interests may come with different tax, transfer and legal complexities. Complicating matters more, not all of these arrangements are available in all states and the rules regarding each of these arrangements may vary from state to state.

How might this matter to you? The potential ramifications associated with each type of interest in property makes it important to secure advice prior to becoming a co-owner of a home, apartment, RV, boat or car or co-signing a loan for any of the foregoing. The potential complexity of the rules can have unanticipated consequences for the unprepared.
