When to split deeds

[Bournbrook]

Hi all. I hope this is in the right section of the forum. 
we have got permission to build a new house in our current back garden which we will then move into and sell the main house. We have a mortgage on current house but only about 30% LTV and estate agents don’t feel that the smaller garden will cause a huge devaluation. I appreciate I need to check with my current mortgage provider whether we can build, but can anyone advise:

 

a) whether we need to apply for the mortgage provider to drop having a  charge on that piece of land?

b) whether we need to apply to split title deeds with land registry before selling main house? I have read they can be funny about doing it unless there’s a change of ownership. 
 

Many thanks

You will need your mortgage provider to agree your scheme.

 

You can then go on to build the new house, sell your existing house as a new title, retaining the land on which the new house is built.

Thank you for this. I came to roughly the same conclusion having been on the phone to land registry and the bank since I wrote this post. 
 

presumably when selling existing house with a new title, this is all dealt with by a normal conveyancing solicitor as part of the normal sale process?

 

thanks again

Yes.  They use a different form.  https://www.gov.uk/government/publications/registered-titles-part-transfer-tp1
