§ 203. Conveyance or incumbrance of trust property of Friends. The trustee or trustees, or survivor of any trustees, of any meeting of the Religious Society of Friends, appointed pursuant to the last preceding section, may sell, convey and grant, mortgage, or demise any or all of the trust property described in said trust deed or declaration of trust, to any person absolutely or in trust for such meeting, whenever any meeting of said society by resolution so directs. Any conveyance or mortgage of real estate or property so held in trust by any meeting of the Religious Society of Friends, which is hereafter made in pursuance of a resolution of such meeting as provided herein, shall be as valid and effectual for the conveyance or mortgage of the title of any real estate so held in trust, as if the heirs of any trustee who has died prior to the passage of such resolution had joined in the execution of such conveyance, mortgage or demise. Any instrument for the sale, mortgage or demise of such property shall embody such resolution, and be executed and acknowledged by such trustee or trustees; and in such acknowledgment such trustee or trustees shall make an affidavit that the person or persons executing such conveyance, mortgage or demise are the trustee or trustees of the trust property, and that the resolution embodied in such conveyance, mortgage or demise was duly passed by such meeting. Such affidavit shall be prima facie evidence of the facts therein stated.
