Jo M - The entry dated 20 January 1992 is a restriction, known as Form A restriction, which is usually entered when the proprietors hold the property as Tenants in Common, though it can also be entered in some other situations. Considering the date when the entry was made it is not possible for me to establish how and who made the application.
Please refer to the guidance in section 3.7.3 of our
Practice Guide 19 on what is required for the restriction to be removed.
I would suggest you seek legal advice before considering removal of the restriction as it could have some other implications which we would not be aware about.
