Abstract: Due to the lack of legal system support,the interests of beneficiaries of pension trust are not well protected in China. The dual disadvantaged status of the beneficiaries of pension trust should be protected by law. To promote pension and trust development in China, the protection mechanism of interests of beneficiaries of pension trust must be established based on this notion. As ex-ante protection, the system of trust supervisor should be set up to ensure the setting trust; as interim protection, the trustee should be required to make prudent investment decisions and the beneficiary's right to know and the payment should be clarified; as ex-post protection, the coverage of damages should be clearly defined.

Key words: pension trust, beneficiary, settlor, trustee, trust property
