He was educated at Reading School under Richard Valpy, was called to the bar 5 May 1809, was created serjeant-at-law 25 June 1827, and became king's counsel with patent of precedence in 1853.
Merewether practised on the western circuit with success. He was appointed recorder of Reading and was attorney-general to Adelaide, Queen-dowager. He received the degree of D.C.L. from the University of Oxford on 12 June 1839.
Elected town-clerk of London on 23 June 1842, over William Pritchard, Merewether then became high bailiff of Southwark. By accepting this appointment he lost a good income at the bar.
