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 large final payment due at the end of a loan, typically a home or car loan, to pay off the amount your monthly payments didn't cover. Many states prohibit balloon payments in loans for goods or services that are primarily for personal, family or household use, or require the lender to let you refinance the balloon payment before forcing collection.

The legally prescribed time limit in which a lawsuit must be filed. Statutes of limitation differ depending on the type of legal claim, and often the state. For example, many states require that a personal injury lawsuit be filed within one year from the date of injury -- or in some instances, from the date when it should reasonably have been discovered -- but some allow two years. Similarly, claims based on a written contract must be filed in court within four years from the date the contract was broken in some states and five years in others. Statute of limitations rules apply to cases filed in all courts, including federal court.

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.

(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.)
