Is it possible to make an effective and irrevocable assignment by way of gift of part of a chose in action? There are no obvious reasons why it should not be possible. Gifts of a great variety of valuable rights are favored and protected by the law. Why not a gift of part of a chose in action? An answer deduced from the decided cases is not in all respects as certain and satisfactory as one might anticipate. Perhaps it is not too much to say that the answer is problematical. The problem invites interest, not only because it appears to be unsettled on authority, but also because it requires some attention to the broader question of the nature of partial assignments.
