5.22 DEFINITION: AFTER-ACQUIRED EVIDENCE is a term used in legal contexts to refer to evidence which is discovered after the dispute or trial has begun. This evidence can be used to support a party’s case, challenge a party’s case, or even to change the outcome of a trial. There are two main types of after-acquired evidence: new evidence which was not previously known or available to the parties, and evidence which was previously known or available but not presented in court. Examples of after-acquired evidence include new witness testimony, physical evidence, electronic records, and documents.
