Buttercup, a few days ago you were asking about a life interest left in a will. Therefore I’m not sure you are just looking at a simple change of name following a death, however you didn’t reply to my questions so I really don’t know your situation. You need to tell us more, but on the basis of what you asked before it sounds as if you do need a solicitor. Nobody can predict what they might charge as it depends on who they are and what you actually need.
When my husband died last summer, I didn’t need probate and all that was required was a death certificate to change the deeds into my sole name. It depends completely on the Will. DH left everything to me, so no problem… Good luck.
