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.

The basis of a contract. Consideration is a benefit or right for which the parties to a contract must bargain; the contract is founded on an exchange of one form of consideration for another. Consideration may be a promise to perform a certain act -- for example, a promise to fix a leaky roof -- or a promise not to do something, such as build a second story on a house that will block the neighbor's view. Whatever its particulars, consideration must be something of value to the people who are making the contract.

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.

(1) A legal principle that prevents a person from asserting or denying something in court that contradicts what has already been established as the truth. equitable estoppelA type of estoppel that bars a person from adopting a position in court that contradicts his or her past statements or actions when that contradictory stance would be unfair to another person who relied on the original position. For example, if a landlord agrees to allow a tenant to pay the rent ten days late for six months, it would be unfair to allow the landlord to bring a court action in the fourth month to evict the tenant for being a week late with the rent. The landlord would be estopped from asserting his right to evict the tenant for late payment of rent. Also known as estoppel in pais.estoppel by deedA type of estoppel that prevents a person from denying the truth of anything that he or she stated in a deed, especially regarding who has valid ownership of the property. For example, someone who grants a deed to real estate before he actually owns the property can't later go back and undo the sale for that reason if, say, the new owner strikes oil in the backyard.estoppel by silenceA type of estoppel that prevents a person from asserting something when she had both the duty and the opportunity to speak up earlier, and her silence put another person at a disadvantage. For example, Edwards' Roofing Company has the wrong address and begins ripping the roof from Betty's house by mistake. If Betty sees this but remains silent, she cannot wait until the new roof is installed and then refuse to pay, asserting that the work was done without her agreement.estoppel in paisSee equitable estoppel.promissory estoppelA type of estoppel that prevents a person who made a promise from reneging when someone else has reasonably relied on the promise and will suffer a loss if the promise is broken. For example, Forrest tells Antonio to go ahead and buy a boat without a motor, because he will sell Antonio an old boat motor at a very reasonable price. If Antonio relies on Forrest's promise and buys the motorless boat, Forrest cannot then deny his promise to sell John the motor at the agreed-upon price.(2) A legal doctrine that prevents the relitigation of facts or issues that were previously resolved in court. For example, Alvin loses control of his car and accidentally sideswipes several parked cars. When the first car owner sues Alvin for damages, the court determines that Alvin was legally drunk at the time of the accident. Alvin will not be able to deny this fact in subsequent lawsuits against him. This type of estoppel is most commonly called collateral estoppel.

A request made to a court, asking it to dismiss a lawsuit on the grounds that no legal claim is asserted. For example, you might file a demurrer if your neighbor sued you for parking on the street in front of her house. Your parking habits may annoy your neighbor, but the curb is public property and parking there doesn't cause any harm recognized by the law. After a demurrer is filed, the judge holds a hearing at which both sides can make their arguments about the matter. The judge may dismiss all or part of the lawsuit, or may allow the party who filed the lawsuit to amend its complaint. In some states and in federal court, the term demurrer has been replaced by 'motion to dismiss for failure to state a claim' (called a '12(b)(6) motion' in federal court) or similar term.

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.

(1) The house in which a family lives, plus any adjoining land and other buildings on that land. (2) Real estate which is not subject to the claims of creditors as long as it is occupied as a home by the head of the household. After the head of the family dies, homestead laws often allow the surviving spouse or minor children to live on the property for as long as they choose. (3) Land acquired out of the public lands of the United States. The term 'homesteaders' refers to people who got their land by settling it and making it productive, rather than purchasing it outright.

Federal laws that prohibit housing discrimination on the basis of race or color, national origin, religion, sex, familial status or disability. The federal Acts apply to all aspects of the landlord/tenant relationship, from refusing to rent to members of certain groups to providing different services during tenancy.

A business guest, or someone who enters property held open to members of the public, such as a visitor to a museum. Property owners must protect invitees from dangers on the property. In an example of the perversion of legalese, social guests that you invite into your home are called 'licensees.'
