Hi George Ellis,
Thank you for your question.
You need to contact the Land Registry direct to check what their requirements are in these circumstances you can call them on 0300 006 0411.
As regards the Income Tax implications you need to complete Form 17 to make the declaration that you want to have the income taxed in that split and accompany this with a copy of the Deed of Trust as evidence that the property is now owned in those shares.
Form 17 can be found on our website here:
Declare beneficial interests in joint property and income
Thank you.
