Lobbyist Law and Legal Definition

A lobbyist is someone who seeks to promote, oppose, or otherwise influence the outcome of a decision maker. Various state and federal laws regulate lobbying activity. Some states set limits on how much money a lobbyist can spend wining, dining and otherwise influencing state officials and laws under consideration. For example, some states require individual lobbyists plus the companies that employ them to register with the state Department of State within a certain time period from taking a job to influence the legislature.
