Where the party concerned requests confirmation of the invalidity of the construction contract, there is no limitation of action.
The determination of the validity of a contract is, in essence, the intervention of the public power of the state on civil acts. The invalidity of a contract is invalid from the beginning, and the mere passage of time cannot change the illegality of an invalid contract.
[Legal Basis]
Article 153 of the Civil Code states that civil legal acts that violate the mandatory provisions of laws and administrative regulations are invalid. However, the exception is that the mandatory provisions do not invalidate the civil juristic act.
Civil juristic acts violating public order and good customs are invalid.
