Walton Eminent Domain Lawyer, New York

A specific legal claim -- such as for negligence, breach of contract or medical malpractice -- for which a plaintiff seeks compensation. Each cause of action is divided into discrete elements, all of which must be proved to present a winning case.

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.

A computer-based service that provides real estate professionals with detailed listings of most homes currently on the market. Much of the information can now be obtained by the public through websites like www.realtor.com.

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.

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-court procedure for resolving disputes using one or more neutral third parties -- called the arbitrator or arbitration panel. Arbitration uses rules of evidence and procedure that are less formal than those followed in trial courts, which usually leads to a faster, less-expensive resolution. There are many types of arbitration in common use: Binding arbitration is similar to a court proceeding in that the arbitrator has the power to impose a decision, although this is sometimes limited by agreement -- for example, in 'hi-lo arbitration' the parties may agree in advance to a maximum and minimum award. In non-binding arbitration, the arbitrator can recommend but not impose a decision. Many contracts -- including those imposed on customers by many financial and healthcare organizations -- require mandatory arbitration in the event of a dispute. This may be reasonable when the arbitrator really is neutral, but is justifiably criticized when the large company that writes the contract is able to influence the choice of the arbitrator.

A rule that allows you to cancel a contract within a specified time period (typically three days) after signing it. Federal cooling-off rules apply this three-day grace period to sales made door-to-door and anywhere other than a seller's normal place of business, such as at a trade show. Another federal cooling-off rule lets you cancel a home improvement loan or second mortgage within three days of signing. Various states have cooling-off rules that sometimes apply even longer cancellation periods to specific types of sales, such as dancing lessons and timeshares.

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.

Compensation to third parties who are injured or whose property is damaged due to the fault of the insurance holder.
