But annoyingdad, the parents can agree that the two weeks she spent at camp are attributable to the dad, or the many Saturday nights she slept at a girlfriend’s house are really Mom’s. The 365 only works with one getting one extra night if all 365 are spent with a parent.
My nephews are assigned by the court 50/50, but there are plenty of swaps. This weekend they are coming to a hockey tourney with their mother (Friday night) and then switching to their father for Sat/Sun. I don’t know whose week it really is, but on Monday they’ll go back to the regular pattern. That means Mom picked up one night or Dad picked up two nights (they switch on Mondays). The next time it might favor the other parent.
FAFSA doesn’t have a counting squad. If the parents agree, that should be enough proof. It is when they don’t agree that it’s a problem, or if the number of nights is really not close to 50/50 and they claim it is.
