Tier 1 Dependent Visa Documentation

Hi,

I am applying for my wife Tier 1 dependant visa. According to the instruction we must apply online using the Visa4UK website.

On the online application form it requested a number of information that normally not required for Tier 1 dependant visa application such as:

* my income proof (payslips etc)
* dependant work details

Should we submit all these data? I thought for dependant application we just need maintenance fund and that's it.

Also it request my Visa details but did not specify if I need to have a certified copy of my visa or not.

Anyone can help?

Thanks
