第十三条（信託財産に属する資産及び負債並びに信託財産に帰せられる収益及び費用の帰属）
Article 13Attribution of Trust Property Assets and Liabilities and of Proceeds and Expenses Attributable to Trust Property
信託の受益者（受益者としての権利を現に有するものに限る。）は当該信託の信託財産に属する資産及び負債を有するものとみなし、かつ、当該信託財産に帰せられる収益及び費用は当該受益者の収益及び費用とみなして、この法律の規定を適用する。ただし、集団投資信託、退職年金等信託又は法人課税信託の信託財産に属する資産及び負債並びに当該信託財産に帰せられる収益及び費用については、この限りでない。
The beneficiary of a trust (but only one who actually has rights as a beneficiary) is deemed to be the one holding the trust property's assets and liabilities; the proceeds and expenses attributable to the trust property are deemed to be the proceeds and expenses of the beneficiary; and the provisions of this Act apply; provided, however, that this does not apply to the trust property assets and liabilities of a group investment trust, retirement pension trust, or Trust Subject to Corporate Taxation, nor does it apply to proceeds and expenses attributable to the trust property thereof.
信託の変更をする権限（軽微な変更をする権限として政令で定めるものを除く。）を現に有し、かつ、当該信託の信託財産の給付を受けることとされている者（受益者を除く。）は、前項に規定する受益者とみなして、同項の規定を適用する。
A person who actually has the authority to make changes to a trust (other than what Cabinet Order prescribes as the authority to make minor changes) and who is meant to benefit from the trust property (other than a beneficiary) is deemed to be a beneficiary as prescribed in the preceding paragraph, and the provisions of that paragraph apply.
