Signed Retainer

Also known as: Signed Case

A fully executed attorney-client retainer agreement between a claimant and a plaintiff law firm, representing the core conversion event in mass tort advertising. The signed retainer is the unit of economic value in campaign measurement — all upstream metrics (CPL, conversion rate, qualification rate) exist to predict and optimize cost-per-signed-retainer. Electronic retainer execution via e-signature platforms has dramatically reduced the time from lead to signed case.
