The use of extrinsic evidence for contract interpretation under Vietnamese Law
Does “extrinsic evidence” exist under Vietnamese law?
Vietnamese law does not specifically deal the concept of “extrinsic evidence”. Extrinsic evidence is usually understood as evidence relating to a contract but not appearing on the face of the contract because it comes from other sources, such as statements between the parties or the circumstances surrounding the agreement.
However, Article 404.1 of the Civil Code 2015 provides that:
“Where a contract contains terms and conditions which are unclear, the interpretation of such terms and conditions shall be based not only on the wording of the contract but also on the intentions of the parties which are expressed before and at the time of preparation and performance of the contract.”
Accordingly, the Civil Code 2015 appears to allow the use extrinsic evidence as a source of the contract interpretation.
