A person having a present interest in personal property, or in the proceeds of the conversion of real estate, which is not in trust, and which is subject to a future interest, shall be deemed to be a trustee of such property, and not a debtor to the remainderman, with the ordinary powers and duties of a trustee, except that he shall not be required to change the form of the investment to an investment authorized for Pennsylvania fiduciaries, nor shall he be entitled to compensation as trustee. Such person, unless given a power of consumption or excused from entering security by the terms of the conveyance, shall be required to enter such security for the protection of persons entitled to the future interests as the court in its discretion shall direct. If a person having a present interest shall not enter security as directed, the court shall appoint a trustee who shall enter such security as the court shall direct, and who shall exercise all the ordinary powers and duties of a trustee, except that he shall not be required to change the form of the investment to an investment authorized for Pennsylvania fiduciaries.
