Allen Landlord-Tenant Lawyer, Kansas

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 legally binding contract in which a person or business promises to treat specific information as a trade secret and not disclose it to others without proper authorization. Nondisclosure agreements are often used when a business discloses a trade secret to another person or business for such purposes as development, marketing, evaluation or securing financial backing. Although nondisclosure agreements are usually in the form of written contracts, they may also be implied if the context of a business relationship suggests that the parties intended to make an agreement. For example, a business that conducts patent searches for inventors is expected to keep information about the invention secret, even if no written agreement is signed, because the nature of the business is to deal in confidential information.

An unforeseen and uncontrollable event that excuses a party to a contract from performing his or her duties under that contract. For example, a landlord can break a lease if the property she agreed to rent accidentally burns down before the tenants move in.

The terms of your contract with an airline after you buy a ticket. Conditions of carriage cover everything from baggage limitations to the amount of compensation you can recover if you're injured on the flight. These provisions often vary from airline to airline. A few, but by no means most, conditions of carriage appear in the fine print on the back of your ticket. To find out about the rest, you can ask the airline for a copy; it is legally obligated to provide one. The conditions of carriage contain a lot of fine print detail and will not make for exciting reading.

A paperless method of entering into an electronic contract. To 'sign' a contract electronically, a person may be asked to click an 'I Accept' button or use a 'key' to encrypt (scramble) information that uniquely identifies the signer using a method called Public Key Infrastructure (PKI). Electronic signatures are as binding as those in ink.

For income and capital gains tax purposes, the value that is used to determine profit or loss when property is sold. Often the basis is what you paid for the property, 'adjusted' to reflect improvements made or damage incurred while you own the property. See stepped-up basis, carryover basis.
