In co-ownerships, most water heaters (electric or gas) are installed within the apartments. In such a case, this device is an integral part of the private portions of the building. Each co-owners therefore has the responsibility to ensure the proper functioning, by checking (notably) any signs of dilapidation, and, if necessary, by replacing it at its own expense. Failing to do so, in the event of a breach, a co-owner could be held liable for any damages to the common areas of the building, as well as to the private portions owned by other co-owners, up to the amount of the deductible provided for the syndicate's insurance coverage.
In the same way as any other natural or legal person, a syndicate of co-owners is likely to incur civil liability towards third parties, including co-owners. Responsibility is the counterpart of power: where authority is, there is responsibility. This responsibility can be translated into the financial contribution of the co-owners, since in the event of a judgment condemning the syndicate to pay a sum of money, this judgement will be enforceable against him and each of the persons who were co-owners at the time the cause of action arose, in proportion to the relative value of their fraction.Therefore the law obliges any syndicate of co-owners to take out insurance covering its civil liability towards third parties.
