Manner of use and maintenance

If the neighbours are jointly entitled to use one of the installations set out in section 921, each of them may use them for the purpose indicated by their nature to the extent that the joint use of the other neighbour is not adversely affected. The costs of maintenance are to be borne by the neighbours in equal shares. As long as one of the neighbours has an interest in the continuance of the installation, it may not be removed or altered without that neighbours approval. In all other cases, the legal relationship between the neighbours is governed by the provisions on co-ownership.
