Consensual contracts are perfected by mere consent. This is the general rule for contracts.

Key points regarding consensual contracts:

• Perfection occurs when there is a meeting of the minds between the parties regarding the object and cause of the contract.
• Until perfected, a contract cannot be an independent source of obligation.
• A contract of sale is an example of a consensual contract.
• No particular form is required for the validity of a consensual contract like a sale.
