It all depends on where you live. Many civil-law countries (e.g. most EU countries) do not recognize trusts, as far as I know.
But even if they do, if you have control over the trust (so you can sell the assets back to yourself), they would disregard the trust and see the assets as owned by you personally anyway, at least for tax purposes.
You have to give up control (trusting︀ that the people managing the trust won't screw you over) for something like this to︁ work.
There was a recent example of an Israeli billionaire who set up a foundation︂ in Liechtenstein. The board members ended up spending his money for their own entertainment (something︃ with jet skis if I remember correctly, among other things), he sued, but the court︄ in Liechtenstein sided with the board (Liechtenstein citizens).
