Thanks for confirming.
This is relatively straightforward.
1. On the basis the property is registered you need form TR1. You and your husband are the transferor and you are the transferee. The form is straightforward to fill in. In the final panel you need to insert the signature clause which is:
Signed as a deed by xxxxxxx In the presence of:
One each for you and your husband. Witness must be over 18 and not related to you or connected with the matter.
2. The signed and dated TR1 needs to be sent to the Land Registry on AP1. There is a £40 fee.
3. If you do this yourself, you and husband need to complete form ID1. This is a form to verify your identify. ID1 goes the the land registry with the TR1 and AP1.
There is no Sdlt if zero or nominal consideration, I.e £1.
Whether there is capital gains tax due is a question for an accountant. It could be a complex question as there are different tax regimes in the two countries.
