İf you are to depend on the contractual liability of the defendants on the basis of your claims then the limitation period should be 10 years from the date of injury.
On the other hand if you shall bring your claims before the courts on the basis of non-contractual (torts)liability then the limitation periods should be considered as in two seperate aspects: the general period of 10 years from the injury date and as the specific period of 1 year which begins in the injured party's being aware of both the damage and the perpetrator(s) identity. Notably, if the injurious act should be classified as a commission of a criminal offense was set forth in any penal act which has a longer period of limitation than that of the one laid down by the Code of Obligations so the plaintiff may avail himself of this.
it must be taken into account that in the cases stemming from the alleged violation of non-contractual liability the burden of proof falls on the plaintiff's(claimant) side concerning both the existence of fault and the damage when this is just the opposite in the contractual liability cases in which the defendant(debtor) is to prove he is free of any fault regarding the breach of contract,e.g. due diligence has been exercised or the damage is caused by the circumstances of force-majeur(will of the god).
