Bequest for illegal purpose or coercion requires legatee to hold property for testator's legal representative. Where a testator devises property on trust for an unlawful purpose apparent on the will, the legatee must retain the property for the benefit of the testator's legal representative; similarly, if revocation of a bequest is prevented by coercion, the legatee must hold the property for the testator's legal representative, creating a resulting trust-type obligation rather than enforcement of the illegal or coerced purpose.
