Tier 2 Dependent documents upload

Can anyone please explain what documents goes which category on Sopra site:
1 for the wife and 1 for a child under 18 I would really appreciate your help. Thanks.

Hey,

If you expand each category, it will list what you need to upload. Yours is a bit different from mine as dependent (Tier 2 General VISA issued May 2014 and extended in October 2016 - so it's not considered for the absence limit).

What I have:
Mandatory:
* Other (previous passports or any travel document used here, police registration, BRP, consent forms)
* Proof of application (current passport)
Optional:
* Sponsors/Employment ( I didn't know where to put so I did here...for the dependent the sponder is the main applicant...so you: marriage certificate, proofs of cohabitation)
* Educational (Life in the UK and English tests certificates);

Thanks for your reply.
Even if I expand it doesn't indicate what type of document they want, it only gives option to upload the file.

The application gives you a list of documents you need to present...that's the minimum you have to submit. Then, reading the guidance and this forum you get the rest (like the cohabitation proof, for example).

Hope it helps
