Trusts require both a trust document and a trustee . . .
those things cost money. You might put someone like one of his brothers or even his ex- in charge of the money, as the trustee, if they'd accept the job. Trustees have potential liability, and have obligations to file tax returns and such.
And you'd have to come up with the conditions of the trust - stuff like what the money can be used for, whether it's an income-only payout or income plus trust corpus - those things can be tough to do if you don't know the kids'/family's circumstances.
It can be done, but someone close to Aruss should be the force behind it, so it gets done right.
