There should be legally valid reasons for seeking cancellation like fraud, suppressing of material facts, undue influence, cheating etc and it is very difficult to establish all these after several years.

You have not posted the complete facts esp. as to why the deed was cancelled.

Why one of the settling party want to rescind his/ her consent ?

Incomplete facts can not lead to form an opinion and oblige.

It is better to consult and engage a local prudent lawyer for appreciation of facts, professional advise and necessary proceeding.
