Hello, my partner has 50% care and custody of children (in which he had to fight for). However, he still has to pay a significant amount of child support to their mother. She works less than full-time hours (chooses not to work full time) rents in her grandmother's house and most likely claims rental assistance and is getting way too comfy with having an additional income for herself. My partner wouldn't mind paying the additional child support if it was actually supporting the upbringing of the children, however, the children return to our house in brand name clothing or expensive new items on a regular basis (I am talking almost every week before Christmas and after Christmas). She and her boyfriend go on several holidays a year whilst the children are left with her parents (she won't allow us to have any additional care of them) and she just bought a brand new car which is worth well over $30000. I should also mention she has her mum, who doesn't work, look after the children on a regular basis for when she is at work. It may seem we are too caught up with her life and are jealous, however, we are struggling to make ends meet on our side. We can hardly afford the small car repayments. We pay rent just so the kids have their own rooms, we try and accommodate and always have to pay for the extracurricular activities such as dancing and singing so the kids have some stability and involvement, we pay for regular school fees and we have the same amount of children expenses to pay for as she is expected (as per the child support agreement). We also pay additional child care fees just so we can work additional hours to make ends meet. Is there a way my partner can pay into an account for the children for when they are older? Is there a way he can pay directly to the additional expenses such as childcare, dancing, sports, additional activities rather than paying his ex for her own spending money? I just find the system to be so unjust in this situation when I, as their stepmum, is even having to pay the additional bills so the kids can benefit? Any suggestions or help are welcome and appreciated.
