My husband is married to another woman?

[imagine]

I dont know, thats why Im also asking about it but as for my basic understanding. Certificate of No Impediment will be issued if you have plan to marry outside the UK and that there is no known obstruction to your proposed marriage.

i dont know if foreign records are checked, there are british people that have ilegaly married again while still married to their first wife, it is illegal but it happens,
where ever your getting your fears ,,paranoia from,
i would advise you to stop worrying, trust your husband if you love him trust his word, if you dont trust him you will spoil your relationship
