The convention for proof is a contract made between companies or between companies and individuals with the objective of defining the means of proof acceptable between the parties, the burden of proof and the payment terms for the settlement of disputes concerning proof. It guarantees the probative value of the documents produced by an electronic signature solution and allows the reversal of the burden of proof to be organised. By using Universign with your regular clients or partners, you can conventionally agree to acknowledge the probative value of contracts completed via Universign.
