In actions in personam, the judgment is for or against a person directly. Jurisdiction over the parties is required in actions in personam because they seek to impose personal responsibility or liability upon a person.64 “In a proceeding in rem or quasi in rem, jurisdiction over the person of the defendant is not a prerequisite to confer jurisdiction on the court, provided that the latter has jurisdiction over the res. Jurisdiction over the res is acquired either (a) by the seizure of the property under legal process, whereby it is brought into actual custody of the law; or (b) as a result of the institution of legal proceedings, in which the power of the court is recognized and made effective. – Frias vs. Alcayde
