Schengen tourist visa: Marriage certificate in english PKN

[Faheemryk]

Dear All

I am applying for French schengen visa
Me and my wife have Pakistani passports

We already had schengen visa from switzerland which is abou to expire now.

I have seen on a website that marriage certificates from outside UK need to be attested by the London Embassy (Pakistan)
for french schengen visa. We didnt do this when we applied for swiss schengen visa
marriage certificate is in urdu and english both and its a computerised marriage certificate

do i have to attest it from Pakistani high commision in london ?
