Documents query for applying along with dependant

[muhandis.ak]

Hi,

I am planning to apply for a Tier 1 visa from Bangalore early next month along with my husband as dependent. Would really appreciate it if someone could help me with a couple of queries. I did search the forums, but got conflicting answers on these points.

1. I'm assuming that our application with go as a joint application, am I correct?

2. Assuming the above is true, would one set of documents suffice (for maintenance fund proof, etc)?

3. In the dependent cover letter, can I safely reference documents attached along with the main applicant's application.

Thanks in advance.
