Aibu? My ex husband and I divorced about 4 years ago we share a son aged 7. Our son lives with me and my new partner and his daughter and he stays with his dad overnight midweek and every 2nd weekend plus Saturday for a few hours when on alternate weekend. My ex also has a partner and they are planning to take our son on his first holiday abroad next year. My ex is insisting I pay for our son's passport saying that he pays a fortune on maintenance and he also pays half after school childcare fees so that covers the passport and I have his birth certificate so I should apply and pay for passport. The maintenance he pays is basic as per csa guildlines. I would contribute to the passport if we were going to take our son away too in near future but we won't be in a financial position to do that for a few years. As he is wanting to go on holiday I think my ex should pay for the passport. AIBU?
