411. An originating application whose conclusions pertain exclusively to a support obligation, child custody or related provisional measures cannot be presented before the court less than 10 days after it is served. The application is tried and determined by preference.
If an application with such conclusions is joined with an application for the annulment of a marriage or a civil union, for separation from bed and board, for a divorce or for the dissolution of a civil union, it is heard in the same manner as an application in the course of a proceeding.
