might be an idea to give the land registry at Lytham st annes a ring and ask them what to do, or have a look on here toi see if there is a form available, might need a solicitor though. http://www.landreg.gov.uk/publications/?pubtyp e=1
You don't need to. But if you want to, telephone your local land registry - they are very helpful and will send you the forms and advise you of any fee.
