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.

Principles of international law so fundamental that no nation may ignore them or attempt to contract out of them through treaties. For example, genocide and participating in a slave trade are thought to be jus cogens.

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 statute, adopted by almost all states, that provides a method for transferring property to minors and arranging for an adult to manage it until the child is old enough to receive it. See custodian.

Insurance that reimburses a mortgage lender if the buyer defaults on the loan and the foreclosure sale price is less than the amount owed the lender (the mortgage plus the costs of the sale). A home buyer who makes less than a 20% down payment may have to purchase PMI.

A right to use property, acquired by a long tradition of open and obvious use. For example, if hikers have been using a trail through your backyard for ten years and you've never complained, they probably have an easement by prescription through your yard to the trail.

A right to use another person's real estate for a specific purpose. The most common type of easement is the right to travel over another person's land, known as a right of way. In addition, property owners commonly grant easements for the placement of utility poles, utility trenches, water lines or sewer lines. The owner of property that is subject to an easement is said to be 'burdened' with the easement, because he or she is not allowed to interfere with its use. For example, if the deed to John's property permits Sue to travel across John's main road to reach her own home, John cannot do anything to block the road. On the other hand, Sue cannot do anything that exceeds the scope of her easement, such as widening the roadway.

(1) An informal written document. A memorandum may be used in any number of circumstances, but most lawyers are best acquainted with the interoffice memorandum--a document prepared by a junior associate in a law office or a judge's law clerk outlining the facts, procedural elements and legal arguments involved in a particular legal matter. These memos are reviewed by senior lawyers and judges who use them to decide how to proceed with the case. (2) Any written record, including a letter or note, that proves that a contract exists between two parties. This type of memo may be enough to validate an oral (spoken) contract that would otherwise be unenforceable because of the statute of frauds. (Under the statute of frauds, an oral contract is invalid if it can't be completed within one year from the date the contract is made.)

Laws that limit the amount of rent landlords may charge, and that state when and by how much the rent can be raised. Most rent control laws also require a landlord to provide a good reason, such as repeatedly late rent, for evicting a tenant. Rent control exists in some cities and counties in California, Maryland, New Jersey, New York and Washington, D.C.
