Do you mean can you claim against the accountants for negligent advice?
Unfortunately, the Limitation Act 1980 is not in your favour. There is a six-year limitation period for breach of contract claims. That period does run from the date of the contract or the date that you have knowledge of the breach (now) but it is subject to a long stop date of 15 years.
I’m afraid that if the accountant raised the defence of Statutory Limitation after 35 years, that defence would succeed. They are unlikely to have any records after 35 years and they could claim that by allowing this to go ahead after that period of time has severely prejudiced their position.
Even before the Limitation Act there has always been the equitable legal maxim, “equity will not suffer delay”.
Unfortunately, I cannot see a claim succeeding therefore.
I am glad to have helped.
