Thanks Maths, very clear.
Regarding our Tenants in Common situation, do I need to inform Land Registry about the change? I wondered if it would necessitate a stamp duty land tax form to be completed?
As we intend to sell the house in the coming years, I want to be sure that the unequal shares wont crop up as a problem here for e.g. CGT allowances.
Many thanks,
Martin.
I don't know if you need to tell HMLR. Note that if you don't, the new deed will still have effect and will apply for tax purposes, but you might be in violation of some other law regarding telling HMLR. Once upon a time you definitely didn't need to tell HMLR but with all the changes regarding transparency of beneficial ownership via trusts that might have changed.
Assuming you're both the only legal owners and the only beneficial owners then you do not need to register the trust with HMRC, it's a schedule 3a excluded trust.

You don't need to do a SDLT return (assuming no consideration)
