Answer ... The arbitration agreement must have a written form - including electronic means of communication - both in domestic and international arbitration.

Provisions regarding domestic arbitration also require an authentic form for agreements which refer to disputes related to the transfer of a property right or the constitution of a real right over a real estate asset.

Answer ... Yes, both international and domestic arbitration provisions state that the arbitration agreement's validity is independent to the validity of the main contract.

Answer ... If there is no agreement between the parties, the seat of the arbitration shall be decided by the arbitral tribunal. As far as the language of the arbitration is concerned, in absence of an agreement between the parties, the language of the arbitration will be that of the main contract, or, otherwise, an international language chosen by the arbitral tribunal.
