A lien obtained under AS 09.38.035 has priority over any subsequent garnishment lien or wage assignment. A writ creating a continuing lien served upon an employer while a continuing lien imposed by a previous writ is still in effect shall be answered by the employer with a statement that the employer is holding no funds and with a further statement stating when all previous liens are expected to terminate. The subsequent writ has full effect from the termination of all prior liens or until it is otherwise terminated under AS 09.38.035. However, a subsequent writ is not effective if a writ in the same cause of action is pending at the time of service of garnishment.
