No percentage cap
Ohio imposes no statutory percentage cap on contingency fees in personal injury or medical malpractice cases. The governing standard is Prof.Cond.R. 1.5 of the Ohio Rules of Professional Conduct, which prohibits an unreasonable fee rather than fixing a specific figure.
Ohio has specifically policed certain fee structures
Rather than a bright-line percentage, Ohio's disciplinary board has addressed specific fee arrangements it considers improper. A 2024 ethics opinion found that converting a contingent fee into an hourly rate if the case settles early or the attorney is discharged can interfere with a client's settlement authority and risk producing an unreasonable fee. A separate 2023 opinion found that a charging lien based on the highest settlement offer received before discharge can similarly burden the client unreasonably. Both opinions apply the same underlying reasonableness standard, not a numeric cap.
A different regime for workers' compensation
It's worth keeping this separate from workers' compensation, where Ohio has historically applied a separate statutory fee cap distinct from Prof.Cond.R. 1.5 — a different legal framework from ordinary personal injury contingency fees.
