3903e - Supplement to Schedule 1 - Background/Declaration question

[ABCml]

My question is with regard to "Please provide documentary evidence to support your claims, e.g. divorce certificate, relationship documents, custody order, etc...

My wife has two previous marriages; the most recent which ended in 2008, in which she has provided the divorce certificate.
- with regard to her first marriage, which ended in 1995, she hasn't provided the divorce certificate.

Does the fact that she was legally married the second time (with all the required supporting evidence and documentation provided) clear her of the necessity to provide the divorce certificate of the first marriage? - i.e., the second marriage, of course, could not have taken place without the (now difficult to acquire) divorce certificate (of the first marriage) presented at the time...

Will this be a sticking point with the assessment our application?

Thank much in advance for any replies!
