You cannot force anybody to take legal action against you, it is entirely up to the lender/solicitors to decide this.(posted 8298 days ago)As to whether you should sue them, you need to talk to a solicitor who is up on property law. Without knowing all the details and seeing all the paper work I certainly would not say to anyone take them to court.
Please give more details about your case, dates, amounts etc as your posting was very light on facts. I appreciate that you are angry with them and fed up with waiting butperhaps that is what they want to happen.
Any more information you can give would be appreciated - a real e- mail address would be a start.
