A real-estate contractor or project promoter is obliged, under certain conditions, to comply with the Act of 9 July 1971 on residential construction and the sale of housing, better known as the "Breyne Act".
This imposes on the contractor or promoter an obligation to provide to the purchaser, when the deed of sale is signed, a guarantee of completion of the works or of repayment. This guarantee is intended to protect the purchaser:
- Against the possibility of bankruptcy or insolvency of the contractor or the promoter.
- In the event that the contractor or the promoter do not deliver construction works that are in accordance with the contract.
This completion bond is generally furnished by a bank, but it can also be issued by an insurer such as Euler Hermes.
