my bank has asked me what will fund my business trust and what my intention are. how should i respond how much am i required to disclose

What is the duty /intent/ and purpose of a Trustee? To manage, grow and add value to the trust.. correct? You are opening an account in commerce on the public side of the ledger.. You are likely required to give a response to their questions. What will fund the trust? I would say Trust business, not fully determined at this point. You've satisfied their question, without commiting to a source of funds.. Maybe even donations to initally fund it??
