The partial validity of an invalid contract means that the contract is not completely invalid. Of course, such a contract cannot be called an invalid contract. It belongs to the partial invalidity of a contract. If it does not affect the validity of other parts, the other parts are still valid.
Legal basis: Article 156 of the Civil Code [Partial invalidity of civil juristic acts] If a part of a civil juristic act is invalid and does not affect the validity of other parts, the other parts are still valid.
