Unlicensed

Practicing without a license (American English) or practising without a licence (British, Irish, and Commonwealth English) is the act of working without the licensure offered for that occupation, in a particular jurisdiction. Most activities that require licensure also have penalties for practicing without a valid, current license. In some jurisdictions, a license is offered but not required for some professions.

Fields where practicing without a license may carry civil or criminal penalties include lawyer, physician, physician assistant, optometrist, surgeon, coroner, medical examiner, paramedic, funeral director, osteopath, chiropractor, dentist, pharmacist, engineer, pilot, broadcasting, nurse, veterinarian, midwife, teacher, psychologist, surveyor, detective, social worker, architect, barber, hairdresser, electrologist, tattooist, cosmetologist, real estate agent, plumber, florist, accountant, and masseuse. If a person offering their services is licensed in one of these professions, any member of the public has a right to know if that person is validly licensed or not by the licensing authority. Anyone who claims to have a license and refuses to identify themselves properly by first and last name can possibly lose any one or all of their licenses. In many jurisdictions, it is illegal for service providers to hide their identities for purposes of making it difficult to verify licensure and past disciplinary actions or license violations.
