Hamilton Land Use & Zoning Lawyer, New York

A legal doctrine that requires landlords to offer and maintain livable premises for their tenants. If a landlord fails to provide habitable housing, tenants in most states may legally withhold rent or take other measures, including hiring someone to fix the problem or moving out. See constructive eviction.

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 legal category of worker defined by the Internal Revenue Service. The key to the definition is that, unlike employees, independent contractors retain control over how the work they are hired to do gets done; the person or company paying the independent contractor controls only the outcome--the product or service.

(1) An informal written document. A memorandum may be used in any number of circumstances, but most lawyers are best acquainted with the interoffice memorandum--a document prepared by a junior associate in a law office or a judge's law clerk outlining the facts, procedural elements and legal arguments involved in a particular legal matter. These memos are reviewed by senior lawyers and judges who use them to decide how to proceed with the case. (2) Any written record, including a letter or note, that proves that a contract exists between two parties. This type of memo may be enough to validate an oral (spoken) contract that would otherwise be unenforceable because of the statute of frauds. (Under the statute of frauds, an oral contract is invalid if it can't be completed within one year from the date the contract is made.)

The loss of property or a privilege due to breaking a law. For example, a landlord may forfeit his or her property to the federal or state government if the landlord knows it is a drug-dealing site but fails to stop the illegal activity. Or, you may have to forfeit your driver's license if you commit too many moving violations or are convicted of driving under the influence of alcohol or drugs.
