Register your home rights
How do I register my matrimonial home rights?
There are different procedures for registered and unregistered property when applying to register home rights.
Registered property means the Land Registry holds a register of the property which includes details such as who owns the property. You can see the register by requesting official copies. To check whether you own the property you should contact the Land Registry and ask to see the official copy for the property.
Unregistered property means details of the property are not held in a register by the Land Registry, but kept in separate documents. These documents are called title deeds. The title deeds will show who owns the property. Title deeds will normally be held by your mortgage provider. If you do not have a mortgage the title deeds should be with an owner or may be held by a solicitor.
Most properties today are registered. You can check with the Land Registry to see if your family home is registered.

If there is no fee then you can enter £0.00 or “no fee” in the box on the form that asks you for the fee.
