Nanuet Landlord-Tenant Lawyer, New York

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.

Personal property that has no physical existence, such as stocks, bonds, bank notes, trade secrets, patents, copyrights and trademarks. Such 'untouchable' items may be represented by a certificate or license that fixes or approximates the value, but others (such as the goodwill or reputation of a business) are not easily valued or embodied in any instrument. Compare tangible property.

A meeting of the minds. An agreement is made when two people reach an understanding about a particular issue, including their obligations, duties and rights. While agreement is sometimes used to mean contract -- a legally binding oral or written agreement -- it is actually a broader term, including understandings that might not rise to the level of a legally binding contract.

A valid contract in which a copyright owner authorizes another person or entity (called the licensee) to exclusively exercise one or more of the rights (or portion of such rights) that belong to the copyright owner under the copyright. The licensee is said to 'own' the rights granted in the license and is referred to as a copyright owner.

An old-fashioned term for a female executor--the person named in a will to handle the distribution of the deceased person's property. Now, whether male or female, this person is called either the executor or the personal representative.

An old legal term that is generally used to refer to real estate left to someone under the terms of a will, or to the act of leaving such real estate. In some states, 'devise' now applies to any kind of property left by will, making it identical to the term bequest. Compare legacy.

A provision in a contract that preserves the rest of the contract if a portion of it is invalidated by a court. Without a severability clause, a decision by the court finding one part of the contract unenforceable would invalidate the entire document.

A non-U.S. citizen who has been given permission to make his or her permanent home in the United States. If you acquire permanent residence, you will be issued a green card to prove it. The terms permanent resident and 'green card holder' mean exactly the same thing. You cannot be a permanent resident without a green card and you cannot have a green card without being a permanent resident. As a permanent resident, you may travel as much as you like, but your place of residence must be the United States and you must keep that residence on a permanent basis. If you leave the United States and stay away for more than a year, you risk losing your green card.
