Article 31 explained in plain English
This article sets two formal requirements for a ship construction contract:
1. Writing: a ship construction contract is proved in writing, as is any amendment to it. An oral agreement to build is not enough, nor is one to later change the specifications, price or schedules.
2. Signature: the contract is valid only if its parties sign it.
In practical terms, the party ordering the ship and the builder need a written contract signed by both, and every change they agree on during construction should also be put in writing. The wording of the text is explicit that an amendment is subject to the same rule of writing.
The wording of the article distinguishes the effect of writing from that of the signature: writing is the means of proving the contract and its amendments, while signature is a condition of the contract's validity. The article does not specify the details the contract must contain.
This article comes among the provisions on the construction and ownership of ships, alongside Article 32, under which ownership of the ship remains with the builder until delivery is accepted after trials, unless agreed otherwise. A person concluding a contract to build a ship can consult a lawyer specializing in commercial cases to draft it.
Practical example
A fishing company in Jazan agrees with a shipyard to build a ship, then they agree orally to change the engine. Under the article, this amendment is proved in writing like the original contract.
