A provision in a deed or will that attempts to restrict ownership of the property -- for example, selling your house to your daughter with the provision that it never be sold to anyone outside the family. These provisions are generally unenforceable.

To take effect, or to benefit someone. In property law, the term means 'to vest.' For example, Jim buys a beach house that includes the right to travel across the neighbor's property to get to the water. That right of way is said, cryptically, 'to inure to the benefit of Jim.'

A valid contract in which a copyright owner authorizes another person or entity (called the licensee) to exclusively exercise one or more of the rights (or portion of such rights) that belong to the copyright owner under the copyright. The licensee is said to 'own' the rights granted in the license and is referred to as a copyright owner.

A legally binding contract in which a person or business promises to treat specific information as a trade secret and not disclose it to others without proper authorization. Nondisclosure agreements are often used when a business discloses a trade secret to another person or business for such purposes as development, marketing, evaluation or securing financial backing. Although nondisclosure agreements are usually in the form of written contracts, they may also be implied if the context of a business relationship suggests that the parties intended to make an agreement. For example, a business that conducts patent searches for inventors is expected to keep information about the invention secret, even if no written agreement is signed, because the nature of the business is to deal in confidential information.

A right to property that cannot be enforced in the present, but only at some time in the future. For example, John's will leaves his house to his sister Marian, but only after the death of his wife, Hillary. Marian has a future interest in the house.

A proposal to enter into an agreement with another person. An offer must express the intent of the person making the offer to form a contract, must contain some essential terms--including the price and subject matter of the contract--and must be communicated by the person making the offer. A legally valid acceptance of the offer will create a binding contract.

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 legal claim placed on real estate by someone who is owed money for labor, services or supplies contributed to the property for the purpose of improving it. Typical lien claimants are general contractors, subcontractors and suppliers of building materials. A mechanics' lien claimant can sue to have the real estate sold at auction and recover the debt from the proceeds. Because property with a lien on it cannot be easily sold until the lien is satisfied (paid off), owners have a great incentive to pay their bills.
