Advocates and law agents usually submitted evidence to the Court of Session in support of a client's claim. Evidence took many forms. Depositions heard by the Lord Ordinary on Oaths and Witnesses (or his designee) became part of the case record. A lawyer might also voluntarily or at the court's behest include a few snippets of correspondence, a ledger extract, or an estate inventory as part of the process. These pieces of evidence were printed in Session Papers as a case moved through the court.
