If an attachment is levied on the assignee before the assignment of the right becomes effective against third parties, the assignment shall, as against the attaching creditor, be deemed equivalent to a further attachment. If a subsequent attachment is levied after the assignment has become effective against a third party, the debt shall be distributed among the prior attaching creditor, the assignee, and the subsequent attaching creditor on a pari passu basis, provided that the assignee shall be satisfied, out of the share of the subsequent attaching creditor, to the extent necessary to complete the value of the assignment.
