Definitions of ambulance chaser
(COLLOQUIAL) a lawyer who specialises in personal injury cases; a lawyer who actively seeks cases (eg at the scene of an accident or in a hospital) that may lead to a large sum of money being paid in damages or as a settlement
The rise in contingency fees (usually a percentage of the amount of the settlement or award) has lead to a new breed of 'ambulance chasers' ruthlessly pursuing possible claims.
