I was interested to read the recent case of IX v IY  which considered the question...
Certificates of title
Birkett Long were requested to provide certificates of title for 24 freehold properties owned by a long-term client.
We used the strength and breadth of our Real Estate Team and the Corporate Team to deal with the high level of work involved, assisted by the substantial prior knowledge of the properties involved and the client’s approach to its business; combined with the specialist experience of dealing with City of London Certificates of title and complex stamp duty land tax transactions.
This specialist expertise and historical knowledge considerably reduced the pressure on the client and together with the size of the team working on the matter, enabled the transaction to conclude fairly smoothly within an extremely tight deadline.
