I could be about to open a can of worms but here goes.
No1 son has an auto entrepreneur registration in the artisan sector which he started up to earn part time money while studying. Now he no longer does that work and is nearly at the end of his studies. His brother No 2 son needs to do part time work. So can no2 son buy No1 sons small business and what are the registration costs going to be? It seems daft to me that one son will stop trading and the other will start dong the same thing at the same address for the same reason.
Has any one any experience before I contact the Chambre des métiers?
