A more thorough explanation:

A Writer to the Signet is a legal professional in Scotland who has special privileges in preparing official documents. The term has two meanings:

1. Historically, a member of the College of Justice, which was founded in 1532.
2. A member of an Edinburgh society of solicitors who hold a few special privileges in the preparation of official documents.

For example, a Writer to the Signet may be authorized to prepare and sign legal documents such as deeds, wills, and contracts. They may also have the authority to certify copies of official documents.

The term "Signet" refers to the seal that was historically used to authenticate legal documents. The Writer to the Signet was responsible for preparing the document and then sealing it with the Signet.

Today, the role of the Writer to the Signet has evolved, but they still play an important role in the Scottish legal system.
