What requirement exists for a witness in a notarial act?

In a notarial act, the requirement that a witness must be indifferent to the transaction is crucial for maintaining the integrity and impartiality of the notarial process. This means the witness should not have a personal stake or vested interest in the outcome of the transaction or document being notarized. By being indifferent, the witness can help ensure that the signing is genuine and that the parties involved are entering into the agreement willingly and without coercion.

An indifferent witness contributes to the overall reliability of the notarized document, as they can provide unbiased testimony regarding the circumstances of the signing if needed in the future. This impartiality helps to prevent conflicts of interest and ensures that the notarial act is conducted in a fair and equitable manner, which is a fundamental aspect of notarial practice.

The other options do not align with the requirements for witnesses in notarial acts. A relationship to the signer could introduce bias, legal training is not a necessity for being a witness, and being a licensed notary would not be appropriate, as the notary's role is to facilitate rather than witness the act themselves in this context.
