Two or more tenants who rent the same property under the same lease or rental agreement. Each co-tenant is 100% responsible for carrying out the rental agreement, which includes paying the entire rent if the other tenant skips town and paying for damage caused by the other tenant.

A rental agreement or lease between a tenant and a new tenant (called a sublessee) who will either share the rental or take over from the first tenant. The sublessee pays rent directly to the tenant. The tenant is still completely responsible to the landlord for the rent and for any damage, including that caused by the sublessee. Most landlords prohibit subleases unless they have given prior written consent. Compare assignment.

A legal doctrine that prevents a plaintiff who has acted unethically in relation to a lawsuit from winning the suit or from recovering as much money as she would have if she had behaved honorably. For example, if a contractor is suing a homeowner to recover the price of work he did on the home, his failure to perform the work as specified would leave him with unclean hands.

An extraordinary and unexpected natural event, such as a hurricane, tornado, earthquake or even the sudden death of a person. An act of God may be a defense against liability for injuries or damages. Under the law of contracts, an act of God often serves as a valid excuse if one of the parties to the contract is unable to fulfill his or her duties -- for instance, completing a construction project on time.

A legally binding agreement involving two or more people or businesses (called parties) that sets forth what the parties will or will not do. Most contracts that can be carried out within one year can be either oral or written. Major exceptions include contracts involving the ownership of real estate and commercial contracts for goods worth $500 or more, which must be in writing to be enforceable. (See statute of frauds.) A contract is formed when competent parties -- usually adults of sound mind or business entities -- mutually agree to provide each other some benefit (called consideration), such as a promise to pay money in exchange for a promise to deliver specified goods or services or the actual delivery of those goods and services. A contract normally requires one party to make a reasonably detailed offer to do something -- including, typically, the price, time for performance and other essential terms and conditions -- and the other to accept without significant change. For example, if I offer to sell you ten roses for $5 to be delivered next Thursday and you say 'It's a deal,' we've made a valid contract. On the other hand, if one party fails to offer something of benefit to the other, there is no contract. For example, if Maria promises to fix Josh's car, there is no contract unless Josh promises something in return for Maria's services.

For income and capital gains tax purposes, the value that is used to determine profit or loss when property is sold. Often the basis is what you paid for the property, 'adjusted' to reflect improvements made or damage incurred while you own the property. See stepped-up basis, carryover basis.

A legal claim that one party failed to perform as required under a valid agreement with the other party. For example you might say, 'The roofer breached our contract by using substandard supplies when he repaired my roof.'
