Thanks for that Shawn. Good point! For all others reading this message it is important that all signatures (ie on FLR forms, ID cards, bank accounts etc are the same as in your passport. So if you obtain an amended passport with married name your signature will obviously still be in your maiden name so stick to your old signature on ALL documents. If you get a completely new passport in your married name enter your new signature on ALL documents. It is important to always be consistent with your signature on everything to avoid confusion with authorities.
A signature is normally just a squiggle in writing - most signatures are illegible therefore it does not matter if maiden or marital name. A signature is basically your unique stamp to prove it is you. The name is not the important thing in a signature (unless it is too obvious what the words say) as all authorities simply use it to check that you are the genuine person signing.
