I’m responding to your posts on your previous thread @CloverRiver
Firstly you kept asking why the school are asking for verification of your income now and not when the care was a 50% split. You also said the mother recently cut contact and made a big deal of this by asking the school to be totally removed with any involvement with her son and behaving in a strange manner. To me, it’s obvious that both are connected.
They didn’t need your income before as both parents were amicable, paying 50/50 and were engaging with the bursary process. But now that she has dramatically flounced off, the step-son’s account has likely been scrutinised in more depth and the school seem to feel the standard of engagement isn’t sufficient for the bursary. The school now want a replacement parental figure on the record and are basically placing you in that role, because it protects the school as they would make you jointly liable for fees.
It’s logical in a sense, because they likely accepted the bursary claim based on the previous set of income declared to them and now that circumstances have changed, need to see if the bursary is still valid.
Unfortunately it may be that they withdraw the bursary in any case, because of the mother withdrawing from the arrangement. Don’t let anyone guilt trip you into making that your fault. The mother obviously signed a contract that she’s now pulled out of, the school are pissed and want to make sure they aren’t going to be out of pocket. But they likely know they aren’t going to get anywhere with chasing the mother so are going after you instead, because your side of the parenting divide is more easy to pressure as his dad cares about the son’s education when the mother doesn’t.
