hi JTA, regarding to your post, you dont need your cenomar as you are already married ..... you just need your marriage certificate.
and for red ribbon theres no need really as the UK embassy didnt ask for documents to have it in red ribbon.
As long as you have your birth certificate from NSO, marriage certificate from NSO and other requirements.
Its better to read and be inform in what other documents you need for your application, its good to visit the ukvac website as the visa fee changes so fast lolthe ukvacs will not accept your application if you didnt pay them the RIGHT visa fee.
