Disclaimer of interest
(重定向自Deed of family arrangement)

In the law of inheritance, wills and trusts, a disclaimer of interest (also called a renunciation) is an attempt by a person to renounce their legal right to benefit from an inheritance (either under a will or through intestacy) or through a trust. "If a trustee disclaims an interest in property that otherwise would have become trust property, the interest does not become trust property."
