An extraordinary and unexpected natural event, such as a hurricane, tornado, earthquake or even the sudden death of a person. An act of God may be a defense against liability for injuries or damages. Under the law of contracts, an act of God often serves as a valid excuse if one of the parties to the contract is unable to fulfill his or her duties -- for instance, completing a construction project on time.

(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 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.'

A portion of profits distributed by a corporation to its shareholders based on the type of stock and number of shares owned. Dividends are usually paid in cash, though they may also be paid in the form of additional shares of stock or other property. The amount of a dividend is established by the corporation's board of directors; however, state laws often restrict a corporation's ability to declare dividends by requiring a minimum level of profits or assets before the dividend can be approved.

A gift of property. The IRS allows you to take an income tax deduction for the value of donations made to charitable organizations who are recognized as such by the IRS.

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.

A guarantee about the quality of goods or services made by a seller, such as 'This item is guaranteed against defects in construction for one year.' Most express warranties come directly from the manufacturer or are included in the sales contract. If you want to hold the seller to an oral guarantee, it's best to get it in writing or have witnesses to the guarantee so that it doesn't come down to your word against the seller's if a problem arises.

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.
