Pseudo-Trust, Thai Nominee

No trust law in Thailand, can't establish trusts as in the UK.

I wonder if there's any way to establish a pseudo-trust for a beneficiary, somewhat reminiscent of the property agreements farangs make w/ their Thai wives. Say, (just to throw out something), make a loan agreement w/ a Thai whereby the Thai borrows a sum of money that must be invested in a certain way, and will receive a regular payment, until such time as the "loan" must be repaid or given to the beneficiary who reaches a certain age. Maybe it could be done thru a company kind of structure. Difficulty as always is how to ensure the Thai doesn't just take the money and run.

Any point in talking to somebody like Sunbelt about this or a reputable lawyer?
