A promise that pledges nothing, because it is vague or because the promisor can choose whether or not to honor it. Such promises are not legally binding. For example, if you get a new job and promise to work for three years, unless you resign sooner, you haven't made a valid contract and can resign or be fired at any time.

A way two or more people can own property together. Each can leave his or her interest upon death to beneficiaries of his choosing instead of to the other owners, as is required with joint tenancy. In some states, two people are presumed to own property as tenants in common unless they've agreed otherwise in writing.

A statement included in a patent application that describes the structure of an invention in precise and exact terms, using a long established formal style and precise terminology. Patent claims serve as a way for the U.S. Patent and Trademark Office (PTO) to determine whether an invention is patentable, and as a way for a court to determine whether a patent has been infringed. In concept, a patent claim marks the boundaries of the patent in the same way as the legal description in a deed specifies the boundaries of the property.

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.

A service contract that covers a major housing system--for example, plumbing or electrical wiring--for a set period of time from the date a house is sold. The warranty guarantees repairs to the covered system and is renewable.

A gift of property. The IRS allows you to take an income tax deduction for the value of donations made to charitable organizations who are recognized as such by the IRS.
