success billing

Definition from Nolo’s Plain-English Law Dictionary

A method for lawyers to bill clients that is based on how the lawyer solves the client's problem, instead of the number of hours the lawyer spends working on it. For example, if a lawyer represents a company that's being sued, they might agree that the client will pay a certain fee if the lawyer settles the case for an amount that the client's insurance policy will cover.
