Interview concern for team entrepreneur

[mbilal77]

I have a question regarding the interview.

I am applying as a Team Entrepreneur Tier 1 with my brother. In my interview they might ask me a question "What will happen to your business if one of the partner backs off and leaves the partnership"

What am I suppose do say for this?
What sort of documents I am supposed to submit that convinces interviewer for this concern.
What will be the best answer for this?

In real both of us (me & my partner) are not going to back off as this is our own money and none us will be interested in taking up any loss.

Kindly help
