Is it a problem to appoint someone who is filing for bankruptcy as a trustee to your investment account?

yea, I think so

Make a temporary app't of your bank or someone from yr. Brokerage house. You can easily change to your partner when he is financially back on his feet. But,...why do you need a trustee for your investment account...are you talking about a will (that can be altered at any time, also) or present-day dealings? I thought you could simply manage your own acc't and get whatever advice you want from wherever you want. Lucky you, BTW, altho sorry about loss of yr father. A place like Vanguard.com will give you free advice over phone if the amt is substantial. Details at their site.They will also give you conservative advice if you have goals and risk factors clear in your head. I have been happy w. them.

That's a good question, perhaps I don't really need a trustee. This is all knew to me. The brokerage service I want to use sent me the paperwork and they highlighted the trustee section for filling out. I will call an inquire if it is really necessary to appoint a trustee.

It is possible that your dad set up a trust, generation-skipping or something more complicated. Don't listen to me Talk to someone competent, like an estate lawyer whom you trust.
