When it is necessary under the provisions of section 473.620 that there be an abatement of specific devises, whether of real or personal property, the court may by order determine the manner in which such abatement shall be accomplished, so that the burden of such abatement will be borne by all specific devisees proportionately according to the value of their respective specific devises, and if any specific devise is sold or applied to accomplish such abatement, the other specific devisees shall be obligated to contribute the respective amounts necessary so that the burden of such abatement will be borne proportionately as provided in this section. The court in its order shall determine the respective amounts to be so contributed and the same may be recovered by the executor or administrator or by the devisees entitled thereto.
