Good Morning
The short answer as regards any Sworn Declaration has no time limit
It not uncommon for the LR to request eclarations if ther s any doubt as to ownership
You have a Lane along the Boundary of your house to which you have no deeds but would like to own it claiming adverse posession.In my opinion you would not suceed because the Land in question has not been fenced from the world at Large for 12yrs at least
As the road is unadopted you could claim one half of the width but it would be subject to any existing rights of way
I am not quite sue whether the Clerk was arguing with you in her personal capacity as ClerkIf it was the former she should have withdrawn from the meeting but she would no doubt argue that she was not entitled to vote on the matter
I do not see that the clerk has done anything wrong as regards the adverts
Hope this assists you
