§ 208. Judgment. In an action brought in a court specified in the last section, final judgment, in favor of the plaintiff, must specify the amount of the lien or the monetary obligation secured by the security interest, and direct a sale of the chattel to satisfy the same and the costs, if any, by a referee appointed thereby, or an officer designated therein, in like manner as where a sheriff sells personal property by virtue of an execution; and the application by him of the proceeds of the sale, less his fees and expenses, to the payment of the amount of the lien or the monetary obligation secured by the security interest, and the costs of the action. It must also provide for the payment of the surplus to the owner of the chattel, and for the safe keeping of the surplus, if necessary, until it is claimed by him. If a defendant, upon whom the summons is personally served, is liable for the amount of the lien or the monetary obligation secured by the security interest, or for any part thereof, it may also award payment accordingly.
