N.J. Stat. § 4:22-52
The person arresting the person offending against the provisions of section 4:22-18 of this title shall take charge of the vehicle and its contents, and all necessary expenses which may be incurred for taking charge of and keeping and sustaining them shall be a lien thereon, to be paid before they can be lawfully redeemed.
If the vehicle and its contents are not redeemed within ten days from the time of the seizure, the person making the seizure shall cause them to be advertised for sale by advertisements published in a newspaper circulating in the neighborhood in which the seizure was made for at least three times in a daily paper or one time in a weekly paper, stating the time and place of the sale and the reason for the sale.
At the appointed time and place such person shall sell the vehicle and its contents to the highest bidder and out of the proceeds thereof shall pay all necessary expenses incurred, paying over the balance to the owner.
If the proceeds of the sale are insufficient to pay such expenses, the balance may be recovered by the person making the seizure from the owner in an action at law.
