Contingency fee agreements eliminate the financial barrier to pursuing a personal injury claim. The lawyer takes a percentage of the recovery instead of charging hourly fees. If the case is lost, the client pays no attorney fees. The concept exists under different names and regulatory frameworks across jurisdictions.

TL;DR.

US: 33% (pre-suit) to 40% (post-suit) of recovery. UK: Conditional Fee Agreement — no fee if lost; success fee capped at 25% of certain damages if won. Canada: 25–33% + tax. Australia: no-win-no-fee similar to UK CFA. Prohibited in most civil law countries.

What the fee buys

  • Investigation and case evaluation
  • Medical records procurement and review
  • Expert witness retention (medical, economic, life-care planning)
  • Demand letter drafting and negotiation
  • Litigation — filing suit, discovery, depositions, trial preparation
  • Risk absorption — the lawyer invests thousands of hours and out-of-pocket costs with no guarantee of payment

Fees vs costs

⚠️
Important distinction“Fees” are the lawyer's compensation for their work. “Costs” are expenses incurred during the case (filing fees, medical records, expert fees, deposition transcripts). In many contingency arrangements, costs are deducted from the settlement in addition to the percentage fee. Clarify this at the outset.
