Can a dependency claim exhaust the resources of an estate?

While it may well be that a dependency claim could exhaust whatever resources were available in an estate, this does not mean that the claim does not exist conceptually. Clearly, however, the dependency claim is to be construed as an "obligation" of the deceased and calculation of the claim under Duncan v. Baddeley is to be assessed as a loss of earnings net of obligations calculated as a present value over the deceased's working lifetime.
