This Practice Note provides guidance on how factual evidence is handled in a civil action in the Scottish courts. It provides an overview of the relevance and admissibility of factual evidence (including hearsay) in Scottish civil litigation before considering the methods of gathering factual evidence, including recovery of documents under the Administration of Justice (Scotland) Act 1972, commission and diligence, witness evidence by commission, and letters of request for witnesses and documents outside of Scotland. It also comments on when it may not be necessary to lead evidence, considering concepts such as judicial knowledge, judicial admissions, and rebuttable presumptions. It discusses disclosure requirements in Scottish civil litigation and the impact of legal professional privilege. It considers the forms of evidence that can be placed before the court (witness, documentary, and real evidence) and how to present that evidence. Finally, it considers where specialist court procedures (for commercial, intellectual property and personal injury actions) contain specific procedural requirements
