CCQ-1991 - Civil Code of Québec

Full text
389. Nullity of marriage extinguishes the right which the spouses had to claim support unless, on a demand, the court, in declaring nullity, orders one of them to pay support to the other or, being unable, owing to the circumstances, to decide the question equitably, reserves the right to claim support.
The right to claim support may not be reserved for a period of over two years; it is extinguished by operation of law at the expiry of that period.
