TIER2 Company Registration Supporting docs Help..

Hello,

Hope someone can help me,

My company is trying to register with UKBA.

Our company is a pvt ltd, We have the following questions,

We have the following documentation.

1. Company audited accounts
2. Employers Liability Insurance
3. Certificate of VAT Registration
4. Company premises Lease.

According to guidelines they require 4 documents (1 from B and 3 from C and a mix of 4)

1.So according to the guidelines is the above documentation is correct ?

2.We have all the digital copies so if we print this out do we have the get it certified via a solicitor before sending out ? Can someone explain me how it can be done ? We're not getting any help from solicitors ?

Thank you.
