The act of changing a written contract when one of the parties can prove that the actual agreement was different than what's written down. The changes are usually made by a court when both parties overlooked a mistake in the document, or when one party has deceived the other.

An unforeseen and uncontrollable event that excuses a party to a contract from performing his or her duties under that contract. For example, a landlord can break a lease if the property she agreed to rent accidentally burns down before the tenants move in.

A person or entity (such as a corporation) that must be included in a lawsuit in order for the court to render a final judgment that will be just to everyone concerned. For example, if a person sues his neighbors to force them to prune a tree that poses a danger to his house, he must name all owners of the neighboring property in the suit.

A non-court procedure for resolving disputes using one or more neutral third parties -- called the arbitrator or arbitration panel. Arbitration uses rules of evidence and procedure that are less formal than those followed in trial courts, which usually leads to a faster, less-expensive resolution. There are many types of arbitration in common use: Binding arbitration is similar to a court proceeding in that the arbitrator has the power to impose a decision, although this is sometimes limited by agreement -- for example, in 'hi-lo arbitration' the parties may agree in advance to a maximum and minimum award. In non-binding arbitration, the arbitrator can recommend but not impose a decision. Many contracts -- including those imposed on customers by many financial and healthcare organizations -- require mandatory arbitration in the event of a dispute. This may be reasonable when the arbitrator really is neutral, but is justifiably criticized when the large company that writes the contract is able to influence the choice of the arbitrator.

An oral or written agreement (a contract) between two people concerning the use by one of the property of the other. A person can lease real estate (such as an apartment or business property) or personal property (such as a car or a boat). A lease should cover basic issues such as when the lease will begin and end, the rent or other costs, how payments should be made, and any restrictions on the use of the property. The property owner is often called the 'lessor,' and the person using the property is called the 'lessee.'

Something that interferes with the use of property by being irritating, offensive, obstructive or dangerous. Nuisances include a wide range of conditions, everything from a chemical plant's noxious odors to a neighbor's dog barking. The former would be a 'public nuisance,' one affecting many people, while the other would be a 'private nuisance,' limited to making your life difficult, unless the dog was bothering others. Lawsuits may be brought to abate (remove or reduce) a nuisance. See quiet enjoyment, attractive nuisance.

A rental agreement that provides for a one-month tenancy that is automatically renewed each month unless either tenant or landlord gives the other the proper amount of written notice (usually 30 days) to terminate the agreement. Some landlords prefer to use month-to-month tenancies because it gives them the right to raise the rent after giving proper notice. This type of rental also provides a landlord with an easy way to get rid of troublesome tenants, because in most states month-to-month tenancies can be terminated for any reason.
