A legal doctrine stating that if a person receives money or other property through no effort of his own, at the expense of another, the recipient should return the property to the rightful owner, even if the property was not obtained illegally. Most courts will order that the property be returned if the party who has suffered the loss brings a lawsuit.

A lawsuit brought by two parties, not as adversaries, but as collaborators in order to resolve a legal question that affects them both. For example, two companies might bring a friendly suit to court in order to clarify a legal interpretation of a contract between them.

Any control over property. If you give away property but keep an incident of ownership--for example, you give away an apartment building but retain the right to receive rent--then legally, no gift has been made. This distinction can be important if you're making large gifts to reduce your eventual estate tax.

In a contract, a promise by one party not to hold the other party responsible if the other party carries out the contract in a way that causes damage to the first party. For example, many leases include a hold harmless clause in which the tenant agrees not to sue the landlord if the tenant is injured due to the landlord's failure to maintain the premises. In most states, these clauses are illegal in residential tenancies, but may be upheld in commercial settings.

A doctrine that prevents a defendant from re-litigating an issue after it has been lost. For example, if your neighbor sues you for putting up a fence on his land and the court rules that your fence extends beyond your property line, you can't later file your own lawsuit seeking a declaration that the property line is incorrectly drawn.

A work created by an employee within the scope of employment or a work commissioned an author under contract. With a work for hire, the author and copyright owner of a work is the person who pays for it, not the person who creates it. The premise of this principle is that a business that authorizes and pays for a work owns the rights to the work. There are two distinct ways that a work will be classified as 'made for hire.'the work is created by an employee within the scope of employment; or the work is commissioned, is the subject of a written agreement, and falls within a special group of categories (a contribution to a collective work, a part of a motion picture or other audiovisual work, a translation, a supplementary work, a compilation, an atlas, an instructional text, a test, or as answer material for a test). The work made for hire status of a work affects the length of copyright protection and termination rights.

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.'

The substitution of a new contract for an old one. A novation may change one of the parties to the contract or the duties that must be performed by the original parties.
