When the assignor and his wife jointly have executed a mortgage upon real property assigned for the benefit of creditors, or when the assignor alone has executed a mortgage upon any of such real property to secure the payment of purchase money, or a part thereof, the probate court shall order its sale free from the contingent right of dower of such wife, and shall determine the just and reasonable value of her dower interests in the proceeds of sale remaining after the payment of such encumbrances as preclude her right to dower therein.
