National is concerned rising court delays aren't being taken seriously by the Government.
Data from October shows family court applications older than two years, have more-than doubled since 2017.
Opposition Courts spokesperson Chris Penk told Mike Hosking it hasn't been a priority, according to the ministerial diary of former Courts Minister Aupito William Sio.
He says in three months, he spent less than ten hours on the issue.
The Justice Ministry says they're trying to work through the backlog which Covid has been responsible for.
