The Society of Writers to Her Majesty’s Signet is a private society of Scottish solicitors, dating back to 1594 and part of the College of Justice. Writers to the Signet originally had special privileges in relation to the drawing up of documents which required to be signeted, but these have since disappeared and the Society is now an independent, non-regulatory association of solicitors. The Society maintains the Category A listed Signet Library, part of the Parliament House complex in Edinburgh, and members of the Society are entitled to the postnominal letters WS.
