Any mechanic or artisan who shall make, alter, or repair any article of personal property at the request of the owner shall have a lien thereon for his just and reasonable charges for his work done and materials furnished, and may retain the same in his possession until said charges are paid; but if possession is parted with by his consent such lien shall cease.

If the amount due and for which a lien is given by § 40-307.01 is not paid after the end of a month after the same is due, and the property bound by said lien does not exceed the sum of $50, then the party entitled to such lien, after demand of payment upon the debtor, if he be within the District, may proceed to sell the property so subject to lien at the public auction, after giving notice once a week for 3 successive weeks in some daily newspaper published in the District, and the proceeds of such sale shall be applied, first, to the expenses of such sales and the discharge of such lien, and the remainder, if any, shall be paid over to the owner of the property.

If the value of the property so subject to lien shall exceed the sum of $50, the proceeding to enforce such lien shall be by bill or petition in equity, and the decree, which shall be rendered according to the due course of proceedings in equity, besides subjecting the thing upon which the lien was attached to sale for the satisfaction of the plaintiff's demand, shall adjudge that the plaintiff recover his demand against the defendant from whom such claim is due, and may have execution therefor as at law.
