I just received my ammended passport and is now preparing for the FLR requirements.

I just wonder because in the FLR form under number 6 of the guidance notes it states that
"to make application valid, ensure that your passport and travel document are signed as required"

Now that is has been ammended to my husband's surname and to coincide with the signature
on the application form do I need to sign or put my new signature on my passport behind the old
signature or just leave the single surname on my passport?

I hope somebody could lighten me on this. Thanks in advance.
