Under the 2020 reformed Civil Code, debt prescription periods are unified: 5 years from knowledge (Art. 166(1)(i)) or 10 years from exercisability (Art. 166(1)(ii)). Prescription must be affirmatively invoked (Art. 145), typically by certified mail. Renewal events include acknowledgment (Art. 152), final judgment (Art. 169), and compulsory execution (Art. 148). Suspension events include judicial claim (Art. 147), demand (Art. 150, 6-month one-time extension), and written agreement to negotiate (Art. 151).
