Hindsight is wonderful I know but the best bet would have been to put several stakes in the ground to mark the original boundary when erecting your new fence.
However, 8 years is nothing when you are talking abut someone having rights over disputed land. The title deeds should show the proper boundary for both your property and that of your neighbour.
Presumably your new neighbour took the boundary line as described by the seller - understandable but solicitor/surveyor should have been able to clarify without a problem.
