6.1 No modification of the contractual conditions is valid or binding, unless it is made by prior written agreement between the shipyard and the owner. It is important to know where you stand if you enter into a painting farm agreement. An agreement can be concluded in all its forms, depending on the different types of paintings (for example. B, entirely, sub-parts, crafts, etc.), the facilities offered and the conditions of the Court. A painting agreement must always be written before the horse is placed in a painting yard. The owner of a paint farm should indicate the provisions relating to the safety of a horse, while the owner must indicate in the agreement all the personal requirements he needs for his horse, to ensure that there is no dispute.
