In its most general sense, the practice of law involves giving legal advice to clients, drafting legal documents for clients, and representing clients in legal negotiations and court proceedings such as lawsuits, and is applied to the professional services of a lawyer or attorney at law, barrister, solicitor, or civil law notary. However, there is a substantial amount of overlap between the practice of law and various other professions where clients are represented by agents. These professions include real estate, banking, accounting, and insurance. Moreover, a growing number of legal document assistants (LDAs) are offering services which have traditionally been offered only by lawyers and their employee paralegals. Many documents may now be created by computer-assisted drafting libraries, where the clients are asked a series of questions that are posed by the software in order to construct the legal documents. In addition, regulatory consulting firms also provide advisory services on regulatory compliance that were traditionally provided exclusively by law firms.
