Whenever there is made a sale, transfer or assignment in bulk of any part or the whole of a stock of merchandise or of fixtures, or merchandise and of fixtures pertaining to the conducting of the business of the seller, transferrer or assignor, otherwise than in the ordinary course of trade and in the regular prosecution of said business, the puchaser, transferee or assignee shall at least ten days before taking possession of such merchandise, fixtures, or merchandise and fixtures, or paying therefor, notify the administrator by registered mail of the proposed sale and of the price, terms and conditions thereof, whether or not the seller, transferrer or assignor, has represented to, or informed the purchaser, transferee or assignee, that it owes any tax pursuant to this local law, whether or not the purchaser, transferee or assignee has knowledge that such taxes are owing, and whether or not any such taxes are in fact owing.
Whenever the purchaser, transferee or assignee shall fail to give the notice to the administrator required by the preceding paragraph, or whenever the administrator shall inform the purchaser, transferee or assignee that a possible claim for such tax or taxes exists, any sums of money, property or choses in action, or other consideration, which the purchaser, transferee or assignee is required to transfer over to the seller, transferrer or assignor shall be subject to a first priority right and lien for any such taxes theretofore or thereafter determined to be due from the seller, transferrer or assignor to the city, and the purchaser, transferee or assignee is forbidden to transfer to the seller, transferrer or assignor any such sums of money, property or choses in action to the extent of the amount of the city's claim.
