Evidence to prove relationship with dependants

[goldenmean]

Hello,
I am applying for Tier1 General Extension(within UK). As evidence of my relationship with my dependants I have below proof -
Wife's Application:
Our marriage registration certificate original, Marriage invitation card, Marriage photos.(This was the evidence provided at initial Tier1 General application)
Question 1] What more proof do I need here, if at all, to prove that our relationship subsits, and valid at time of extnesion application . My UK rental home lease agreement is fully in my name and does not mention about my wife?

Daughter's(minor) application:
Her birth certificate mentioning both parents name.
Question 2] Would I need any more evidence here, if yes what is it?

thanks,
-AD

Is your wife and your child already in the UK? If so, you do not need to provide evidence of "subsisting relationship". Marriage certificate and child(ren)'s birth certificate will suffice.
