<prompt> Human: Im hoping this isnt to niche for this sub I suspect it isnt :- A good friend of mine is 77 and would like to set up a trust fund for his 25 year old son who, for medicalpsychological reasons, does not always make sound decisions. He called me the other day very anxious because he wants to set it up soon, but has no idea where to start.From the information I was able to gather, it seems like its a good idea to go to a company that specializes is trusts though, admittedly, some of that comes from company websites. I have a bunch of questions, but the biggies are:1 Should he go to a trust company over a bank?2 Is it different if he wanted to place restrictions on the funds say, automatically pay rent or mortgage; allow withdrawal only with a second authorized party?3 Does his age or amount he can invest make a difference?  <response>: Sounds like he wants a spendthrift trust. A local estate planning attorney is who you should consult with.
