We are selling our house privately (in Scotland) and got a sale quotation from solicitor before we started which we agreed. Today, as we are handing over the keys they have said that they are adding an extra £1200 to bill for work that was done when we had previously tried to sell the house with them 3 years ago. At that time we took house off market and settled the account with them. I can't believe this is happening. We are livid 
Surely this is not legal! Of course we are going to complain but looking for others opinions on this in the meantime. We had no choice but to pay otherwise sale will not go through.
