Legal subjectivity:

If the contract is signed and sealed but not signed, it is valid if it meets the following conditions: the actor who signed the contract has the corresponding capacity for civil conduct; the actor who signed the contract expressed his intention Authenticity; the content of the contract complies with laws, regulations and public order and good customs; other legal valid conditions, etc. Legal objectivity:

Article 490 of the Civil Code: If the parties conclude a contract in the form of a contract, the contract is established when both parties sign, seal or fingerprint it. Before signing, sealing or fingerprinting, one party has performed its main obligations and the contract is established when the other party accepts it. Laws and administrative regulations stipulate or the parties agree that a contract should be concluded in written form. If the parties do not use written form but one party has performed its main obligations and the other party accepts it, the contract is established.
