The derogation provided for in the fourth paragraph of Article L. 526-22 only applies to claims arising from the date of registration in the register to which the sole trader is subject for his business, where this is provided for. Where he is registered in more than one register, the derogation takes effect from the earliest date of registration.
Where the date of registration is after the declared date of commencement of business, the derogation takes effect from the declared date of commencement of business, under the conditions laid down by decree in the Conseil d’Etat.
If there is no obligation to register, the derogation runs from the first act that he carries out as a sole trader, this status having to appear on documents and correspondence for professional use.
