The Breyne Law is a buyer protection law. It restricts contractual freedom in favour of the acquirer — and these protections are inescapable.

1. Public-order status

Unlike most civil rules, the Breyne Law is of public order. Concretely: no contract clause can make you waive your rights. Even if you signed without reading, the protections remain activatable.

2. Your acquired warranties

Three protection pillars:

  • 5% security deposit (details) blocked at the notary or via bank guarantee.
  • Completion guarantee (Article 12) in case of developer bankruptcy.
  • Two-step reception (Article 9): provisional then final after 1 year.

3. Your remedies

If a mandatory clause from Article 7 is missing, you can claim contract nullity — invocable without time limit as long as the final reception has not taken place.

In case of warranty breach, see developer recourse and Breyne Law sanctions.

Our Breyne Law advisory audits your contract before signing and supports you until the final reception.

Buyer questions

Can I waive the Breyne Law?
No. The Breyne Law is of public order: any contractual clause restricting its scope is void. Even if you sign, your protections remain acquired.
What remedies if the developer does not comply with the law?
Contract nullity invocable without limit, compensation, or forced execution. See developer recourse.
