When an assignment has been made for the benefit of creditors, in another state, and an estate or interest in real property or lands in this state has been heretofore vested or shall hereafter vest in the assignee or other trustee under said assignment, the trust shall cease at the expiration of twenty-five years from the time when the trust was created, except where a shorter limitation is contained in the instrument creating the trust; and the estate or interest in the real property or lands in this state, remaining in the trustee or assignee, shall thereon revert to the assignor, or to his heirs or assigns, as if the trust had not been created.
