If you own a one-man business you are personally liable for all professional debts. If so, your family home could be attached.
To avoid this a statement can be filed with the civil-law notary which is registered at the mortgage registry office. This involves costs, but your family home can no longer be attached.
This does not apply for the content of the family home!
The principle of separate assets does not apply for all companies. A partner of a general partnership or an ordinary limited partnership, for example, remains personally liable for the company’s debts and if so it is advisable to deposit a declaration of non-attachability of the family home with the civil-law notary.
