A contingency fee is a payment structure where the lawyer is paid a percentage of whatever the client recovers, with no upfront cost and nothing owed if the case loses. It's the standard fee structure for personal injury cases in the United States.
Skyline Legal's published PI contingency tiers are 33.3% pre-suit, 40% if suit is filed, and 45% on appeal. Costs (court filing fees, expert witnesses, deposition transcripts) are separate and itemized.
Contingency fees give clients access to representation they otherwise couldn't afford and align the lawyer's incentive with the client's: the firm only gets paid when the client gets paid.
