A more thorough explanation:

A waiting clerk was an officer who attended the court of chancery. Their duty was to wait in attendance and assist the court as needed. However, this position was abolished in 1842 by the Court of Chancery Act (St. 5 & 6 Vict. ch. 103).

During the 18th and 19th centuries, waiting clerks were an important part of the court of chancery. They were responsible for keeping records, preparing documents, and assisting the judges. For example, if a judge needed a particular document or piece of information, they would call on the waiting clerk to provide it.

This position was eventually abolished due to changes in the court system and the need for more efficient processes. Today, the duties of a waiting clerk are typically handled by other court officials or administrative staff.
