A paralegal is an individual who is trained to assist a lawyer or a group of lawyers in the delivery of legal services to clients. Paralegals generally have some training, but are not trained nor qualified to provide legal advice to clients themselves. Through a formal program of training coupled with practical experience, paralegals develop the knowledge and expertise to undertake work of a legal nature under the supervision of an attorney. A paralegal is usually employed or retained by a lawyer, law office, corporation, governmental agency or other entity that performs legal work.
