(Looked for a CM board but there isn't one so wasn't sure where to post)
Basically as background, child maintenance is dependent on the number of days the non-resident parent has their child per week. Relevant choices here are either 0-1 or 1-2. He has our children one overnight per week - school pick up (3.30pm) to drop off the next day (9am).
I would say this isn't a full day so it counts as 0-1 but he thinks 1-2 - any advice would be helpful!
