I’m wondering if anyone can answer a few questions regarding residency orders. I have 4 children with my ex. He is absent and has been for 3 years. Doesn’t pay maintenance at all and have no idea where he is. Literally no contact. This was his choice. He is on 2 of their BC. We are going away in the summer abroad and obviously I know technically I need his “permission” which I can’t get. If I get a residency order will that apply to both children or would I have to apply for one for each? Also how long do they last? And will they inform ex that I have applied for one? Can he object to it? Thanks
