I want to thank everyone who answered my question.
I am going to call my local land registrar and ask them what I need to do. It is only a putting of my name on the deeds instead of my husbands.So there will be no monetary exchanges involved.
My husband inherited the properties from his parents who had owned them since the 1950's. So we have no value to go on as we have never really had them valued.
If there is stamp duty to pay, I will let you know.
