Investor liability under Art. 6471 k.c. does not require prior sub-contractor contract submission before work begins.

The court ruled that the investor's liability under Article 6471 of the Civil Code was not contingent on submitting a sub-contractor agreement before construction commenced. The plaintiff argued that formal documentation was necessary prior to work, while the defendant contended that the law only requires the contract to be signed before payment. The court determined that the statute does not mandate the physical delivery of the contract before the start of operations, allowing the claim to proceed.
