/ˈsiːkrət trʌst/ – Phrase
Definition: sở hữu tín thác được thiết lập trên lời nói.
A more thorough explanation: A secret trust is a trust that is not expressly stated in a will or other legal document, but is instead created through an understanding or agreement between the testator (the person making the will) and the trustee. The trustee holds the property for the benefit of a beneficiary, but the existence of the trust is kept secret from others.
Example: In the case of a secret trust, the trustee holds the property for the benefit of a beneficiary without disclosing the trust in the will.
