Objection to the partial assignment of a debt is personal to the debtor and cannot be raised by a third person. Moreover, the right to raise such an objection may be waived by the debtor.[i] The right to refuse to recognize partial assignments of a debt is also consistent with the principle that a debtor has the right to decline serving as a pro rata disbursing functionary for his/her creditors.[ii]
