Examining the practice of the sale of ongoing businesses can sometimes allow one to note an interpretation of texts that is contrary to the spirit of the legislator. It may be that the sales of craft businesses are therefore qualified as sales of ongoing businesses. The search for the preferential liens that are likely to affect the sold business requires that several statements of the registrations of existing preferential liens be requested. The notion of turnovers and profits mandatorily mentioned in the sale and purchase agreement requires a particular review of the accounting documents. The allocation of parts of the price is not insignificant in the search for the preferential liens that are likely to guarantee the bank loan or deferred payment. The principles of strict interpretation of the texts and speciality of the preferential liens, at the time of their registration, must be observed. A contrario, certain texts relating to the sale of ongoing businesses become unsuitable for the development of the life of the business, for the composition of the business. The sales of craft businesses should be aligned with those of ongoing businesses; the basis of the pledges should include the goods; the seller's preferential lien should be indivisible; the deadlines given to creditors to object to the price and given to register the preferential liens should be extended
