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.'

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 loan in which the borrower puts up the title to real estate as security (collateral) for a loan. If the borrower doesn't pay back the debt on time, the lender can foreclose on the real estate and have it sold to pay off the loan.

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.

The historical term for what is now called the Bureau of Customs and Border Protection ('BCBP'), a branch of the Department of Homeland Security.

The many types of information presented to a judge or jury designed to convince them of the truth or falsity of key facts. Evidence typically includes testimony of witnesses, documents, photographs, items of damaged property, government records, videos and laboratory reports. Rules that are as strict as they are quirky and technical govern what types of evidence can be properly admitted as part of a trial. For example, the hearsay rule purports to prevent secondhand testimony of the 'he said, she said' variety, but the existence of dozens of exceptions often means that hairsplitting lawyers can find a way to introduce such testimony into evidence. See also admissible evidence, inadmissible evidence.

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.
