Definition: quyền ủy quyền lại.
A more thorough explanation: The legal English definition of the term “power of substitution” refers to a provision in a legal document, such as a trust or a will, that grants the person holding the power the authority to appoint a substitute or successor to act in their place. This power allows the individual to designate someone else to take on their role or responsibilities under the document.
Example: The power of substitution allows the trustee to appoint a successor trustee in the event of incapacity or resignation.
