If you have filled in neighbors, then right after elimination of leakage it is necessary to take part in survey of the damaged room. After that it is possible to resolve dispute peacefully or to sue neighbors, defending the correctness.
If you have filled in neighbors, then it is necessary to participate in drawing up the inspection certificate of their apartment. Such act is necessary not only to injured neighbors, but also you as it is required to define all consequences precisely. Usually injured party itself invites responsible for leakage for survey, in addition attracting other neighbors, representatives of management company or condominium. Nevertheless, in the absence of the invitation from neighbors it is not necessary to take the initiative of survey of their apartment and drawing up the act independently. If this document is not made right after neighbors have seen damages, then forcibly it will be much more difficult to receive from you money. Therefore neighbors in this case are interested in that quickly and in common to record the caused damage on paper.
At survey of the damaged apartment it is necessary to evaluate attentively information which registers in the drawn-up statement. This document is signed by all persons participating in survey therefore at disagreement with any point it is recommended to declare availability of objections, to reflect them in the act in writing. If objections refuse to enter in the act, then it is not recommended to sign such document, and it is necessary to try to record independently those damages which confirm your position (for example, by means of photography or shooting). It is necessary to consider that it is not enough to reflect types of damages in the act, it is also necessary to point to their degree, character, the area, other parameters. So, at damage of wall-paper or ceiling it is indicated not only deterioration in finishing, but also the square which it has affected.
If you have filled in neighbors, then there are only two ways of resolving the situation: peace arrangement and compulsory collecting amount of damage. Usually neighbors try to agree independently as are not interested in long trials. If you agree to pay them any sum without court, then it is necessary to reflect, at least, in the receipt the purpose of transfer of money (what they are paid for). Otherwise neighbors can show dishonesty and file a lawsuit all the same, despite the arrangement. Sometimes it is impossible to agree therefore repair cost and purchases of new things will be collected in court.
