If the levying officer obtains custody of an instrument levied upon and serves the obligor under the instrument pursuant to the levy, the obligor shall make payments to the levying officer as they become due. Payments made to a person other than the levying officer do not discharge the obligation of the obligor to make payments as required by this section if the payments are made after the obligor has received notice of the levy.
