Construction

Contracts for the delivery of work, including the delivery of building works, are, together with the rules of general contract law (as governed by articles 1101 – 1369 of the old Belgian Civil Code for contracts entered into before 1 January 2023 and by book 5 of the new Belgian Civil Code for contracts entered into after 1 January 2023) primarily governed by Articles 1787 and the subsequent articles of the Belgian Civil Code. For example, the latter article governs the liability of the contractor or developer and the architect, and also deals with the event of a unilateral termination of a contract.

The mandatory Law of 9 July 1971, relating to house construction and the sale of houses to be or being built (and on execution of that piece of legislation, the Royal decree of 21 October 1971), plays a dominant role in regulating contracts relating to residential construction activities. This legislation implements a number of measures to assist purchasers. In relation to consumers, some of the mandatory provisions of Book VI Market Practices and Consumer Protection of the Belgian Code on Economic Law must also be taken into account.

Government contracts are mainly governed by the Law of 17 June 2016 on public procurements, but also by a (distinct) law of 17 June 2016 (on government concessions), the Law of 17 June 2013 (on the procedure) and the Law of 13 August 2011 (defence contracts), as well as a number of royal decrees. Considering the law on government contracts is for a large part an implementation of European Directives, the main principles of European Law (eg non-discrimination; free movement of persons, goods, services and capital) apply as well, as do the directives themselves in case they differ from the Belgian implementation.

The above laws and regulations are supported by additional sources of law, such as customs of the building industry, as well as relevant case law.

Design

Belgian legislation does not separately deal with contracts for the design of work and therefore generally, the rules of general contract law are applicable to design work. Nonetheless, the Belgian Civil Code contains a number of articles which regulate the relationship between the architect and his principal.

Since the profession of an architect is, according to Belgian law, a regulated profession, an architect will principally also need to comply with a number of deontological or ethical rules, characteristic to the profession of an architect. An architect must be a member of the Belgian association of architects. Architects are not allowed to have any contractual relationship with contractors and must remain independent in their relationships they have with the owner / developer and with the contractors.

However, if a contracting authority aims to appoint an architect for a public contract of (design) services, it should comply with the rules set out in the aforementioned Law of 17 June 2016 on Public Procurement, together with its respective implementing royal decrees.
