Attorney failed to carry out his duties

In the Bahamas complaint made against an attorney that the attorney failed to carry out his professional duty by failing to stamp and record mortgage documents in a timely manner. Complaint was related to work carried about by the attorney some15 to 20 years ago. There were multiplicity of issues with complaint 1. complaint only made recently was about legal matters that happened more than 15 to 20 years ago; Attorney return documents to complainant within the same time period (15 to 20 years ago).
There are other issues but can be discussed once we agree to hiring you to do the work.
The complaint use as its authority the Bahamian case BETHELL (RE) 1984 BHS J NO. 55
I need legal research Privy Council or English cases to counter the BETHELL (RE) case
i will provide a copy of the bethel case.
