Which statement describes 'Legal acts' in a contract?

• A. The service offered must be illegal
• B. The service offered must be paid for
• C. The service offered in the contract must be legal
• D. The service must be performed by a licensed attorney

Answer: (C)

In contract law, the obligation described must have a lawful objective. If the service in question is illegal, the contract cannot be enforced and is considered void from the start. That’s why the statement that the service offered in the contract must be legal best describes a “Legal act.” It ensures the agreement rests on a permissible, enforceable purpose, which is essential for validity.

In dental practice, this means the contract should outline services that are legally permissible and conductible within professional and regulatory rules. Simply requiring payment or needing the service to be performed by a licensed attorney does not define the act’s legality; a contract can be about legitimate dental services performed by eligible professionals, but it would fail if it tried to commit or promise illegal acts.
