Tier 2 General Dependent Help

[xor83]

I have tier2 General Visa as main applicant and I got approved and received my passport. I want to apply for my wife and child. I have following questions:

1) While filling the form for wife and kid, why there are asking for financial bank statements for both?

2) While applying for my wife I need to submit marriage certificate document but on our marriage certificate my DOB is incorrect. Will this create any issues? Should we add some kind of letter or government affidavit stating its wrongly printed and all other documents have correct DOB?

Getting marriage certificate corrected in covid is nearly impossible right now.

1. If your sponsor has not certified maintenance for your Dependents you need to prove maintenance funds

2. Briefly explain in a cover letter. It should not be an issue
