Effect of Contract for Sale or Transfer of Property Which was

Previously Disposed of by Will. If a testator who has made a testamentary disposition of property subsequently enters into an agreement for the sale or transfer of such property, such agreement does not revoke such disposition; but such property passes by the will, subject to the same remedies on the testator's agreement, for specific performance or otherwise, against the devisees or legatees of such property, as might be had against the testator's successors, if such property had passed by succession.
