Cook Land Use & Zoning Lawyer, Nebraska

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 doctrine that prevents a defendant from re-litigating an issue after it has been lost. For example, if your neighbor sues you for putting up a fence on his land and the court rules that your fence extends beyond your property line, you can't later file your own lawsuit seeking a declaration that the property line is incorrectly drawn.

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.

The substitution of a new contract for an old one. A novation may change one of the parties to the contract or the duties that must be performed by the original parties.

A lawsuit brought by two parties, not as adversaries, but as collaborators in order to resolve a legal question that affects them both. For example, two companies might bring a friendly suit to court in order to clarify a legal interpretation of a contract between them.

Property that is subject to use by another for a specific purpose. For example, a beachfront house that has a public walkway to the beach on its premises would be a servient tenement.
