My exH is moving in with a woman who has a 15yo son. She also has a 20yo daughter who is going to be staying with them, along with her boyfriend and their baby.
He wants to reduced child maintenance as there will be 2 children in the household. I accept he should account for the 15yo, although the new girlfriend works and he has told me she will be paying him rent and presumably bills etc. But I don’t see how he can count the baby- surely the baby’s parents are responsible?
