Which law applies?
If you enter into an agreement with a German party, the question may arise as to which law applies to that agreement. Is it Dutch law or German law? If you haven’t made any agreements on this matter in the agreement or general terms and conditions, you’ll find the answer in a European regulation (the ‘Rome I’ Regulation). This regulation stipulates that the law of the country where the supplying party is established applies. So, if you supply a product or service to a German customer, Dutch law generally applies.
Do you supply to consumers (B2C)? Then, in certain circumstances, German law may also apply. Regardless of the applicable law, your terms and conditions must comply with German consumer law.
Vienna Sales Convention (CISG)
Do you supply movable property to a professional party (B2B)? Then you may also need to consider the provisions of the Vienna Sales Convention (CISG). This convention contains provisions regarding, among other things, the quality, payment, delivery, and non-conformity of goods, as well as the termination of sales contracts. Incidentally, the CISG itself defines what is considered “moveable property.” This may mean that even contracts that you would classify as construction in the Netherlands—for example, prefabricated construction—fall under certain conditions under the CISG.
The CISG will only not apply if you have expressly excluded the applicability of this Convention in the agreement or the general terms and conditions.
Note: it can be advantageous, especially for sellers, not to exclude the Vienna Sales Convention. It’s important to seek advice on this before doing cross-border business.
