Dsd is 2 now going to be living with us 5 nights and at her mum's 2 nights a week. Previously it was the other way and we paid full csa requirements as we were not the RP.
She is doing this as she will be going to college this year and its closer to us. it will be like this for the whole year as she also does some work close to us, so no change on holidays.
Now she will live here in the week but they want to still call her mother's her residence.
I checked the csa calculator and it says that we would still have to pay a certain sum each week.
Now I dont understand why, given the mum never had to pay us for the 2 days when it was the reverse.
