First of all, a preliminary purchase contract doesnt exist. It is a binding deed in which the parties are obliged to cooperate in the transfer of ownership of a house. The fact that it is popularly called ‘provisional’ has to do with the fact that at least one resolutive condition is included in a private sale. This concerns a reflection period of three days from the moment of signing for the buyer. As long as this has not expired, the buyer can still cancel the agreement by dissolving (this is possible without stating reasons). Furthermore, other reservations are often included, such as a financing reservation that includes a period within which the buyer must arrange a mortgage. If this doesn’t work, it can be dissolved on the basis of this. An architectural survey can also be included as a reservation. In principle, everything that the parties agree on can form part of the deed as a resolutive condition. But this is certainly not without obligation. For example, invoking dissolution on the basis of, for example, the financing reservation will have to be proven on the basis of a formal rejection by the bank.
