A provision in a deed or will that attempts to restrict ownership of the property -- for example, selling your house to your daughter with the provision that it never be sold to anyone outside the family. These provisions are generally unenforceable.

(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 contract in which an owner leases her house (usually for one to five years) to a tenant for a specific monthly rent, and which gives the tenant the right to buy the house at the end of the lease period for a price established in advance. A lease option is often a good arrangement for a potential home buyer because it lets him move into a house he may buy without having to come up with a down payment or financing at that time.

A law adopted by some cities or towns with desirable vistas -- such as those in the mountains or overlooking the ocean -- that protects a property owner from having his or her view obstructed by growing trees. View ordinances don't cover buildings or other structures that may block views.

Two or more tenants who rent the same property under the same lease or rental agreement. Each co-tenant is 100% responsible for carrying out the rental agreement, which includes paying the entire rent if the other tenant skips town and paying for damage caused by the other tenant.

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 contract giving written permission to use an invention, creative work or trademark. A license provides a way to make money from your invention or creative work without having to manufacture and sell copies yourself. By licensing an invention or work to a company, you get money (often in the form of royalties) in return for allowing the company to use, produce and sell copies of your invention or work in the marketplace.

A promise that pledges nothing, because it is vague or because the promisor can choose whether or not to honor it. Such promises are not legally binding. For example, if you get a new job and promise to work for three years, unless you resign sooner, you haven't made a valid contract and can resign or be fired at any time.

A provision in a lease that absolves the landlord from responsibility for all damages, injuries or losses occurring on the property, including those caused by the landlord's actions. Most states have laws that void exculpatory clauses in rental agreements, which means that a court will not enforce them.
