Shebird - it's NOT being penalised for being a couple - the per parent per child aspect of the fine is eve plied in the case where parents are separated or divorced.
It is genuinely per parent per child.
So if my Ex decided to take my DC's out of school on a Friday before his access weekend to go on holiday, I would get fined as well as him, even if I was unaware that he had done so, and did not give my permission for that to happen.
In situations where both estranged parents have PR, this is even MORE unfair than if a couple decide together to ignore the fact that they will get fined for an unauthorised absence, because neither parent can stop the other from removing the child/rent from school if it is a Court Ordered Contact day for the other parent, yet both get fined.
If the NRP doesn't tell the RP that they are going to do this, then the RP can't write a letter to prevent themselves from getting the fine applied, and the RP will have to pay the fine too.

I would say that that is significantly less fair than the situation where a couple decide together to take the DC's out of school, BOTH having the knowledge that this us going to happen, it will be unauthorised, and that they will both have to pay a fine.
In the case if separated parents, the first that the parent who HASN'T made the decision to have an unauthorised absence might hear about it is when the fine letter drops on their doormat, especially at Secondary, where there is less communication between school and parent...
