A Trustee can be an individual or a trust company. It is better not to entrust your assets to individual trustees because such an individual can die (and you could end up having your assets commingled with his or her) or embezzle the money to the detriment of the beneficiaries.
It is better to look for a trust company regulated by Monetary Authority of Singapore. In Singapore, all trust companies must be regulated by the MAS.
Frankly speaking, nobody and no company can be fully trusted. Having a regulator to be a watchdog is the best you can do.
