A voluntary jurisdiction process is used when there is no conflict between the parties, but the intervention of a judge is needed to validate or authorize certain legal acts. It is common in situations such as adoption, the declaration of heirs without a will, or when judicial approval is required for important decisions regarding the assets of minors or persons incapable of making decisions for themselves. In short, it is a necessary procedure to comply with legal requirements in certain situations, even if there is no disagreement between the parties.
