 When clients deal with KrioRus, they sign a contract to carry out scientific experiment on the preservation and revitalization of a human, and at the same time KrioRus demands that the customer acknowledges the fact that the contractor does not provide guarantees to revive the cryopatient.The agreement covers safekeeping of the bodies for up to 100 years, with the possibility of extension.Maria Bast, chairman of the Russian Lawyers Association for Human Rights, have said that the status of KrioRus as a scientific organisation is justified, and the problem stems from the lack of legislation in the field of cryonics.
