Thinking of divorce, so this is hypothetical, but DH is from Australia. He’s understandably keen for the kids to see his family. His Dad can’t travel for health reasons. His sister has 4 kids and can’t afford it. We’ve been a few times as a family, What kind of rights would he have to take the children abroad for several weeks at a time? They are young (2&5), though they’d be a bit older by time we divorced, but still young to go that long without me.
