Gap year and uni support

[1g1b]

My SO has 18 old with X. 18yo finishes ALs this month. The X insists he pay for full costs while 18yo stays home for a gap year before uni. She also believes full CM continues until September in line with CB and not this month as 18yo finishes school.
She also believes that SO should be the only one to support 18YO when she starts uni. SO’s x only works part time and refuses to increase. My So has always paid above CM in school trips, mobiles, clubs and extra-curricula lessons etc as well as contributed to uniforms whenever asked
I feel she should contribute to gap year and uni support, otherwise the SO is effectively supporting her indirectly by covering her share of supporting child in gap/uni
Question is does CM finish in the last month 18yo attends school (i.e. this month) or when CB stops?
Is it usual for Xs to remain in dependent mode and expect/get continued support?

OMG I can’t believe all this entitled ‘gap year’ and daddy will pay for me mentality.

The boy has decided to take a year off. Upto himself to fund that year. Does he think he’ll always be funded? Maybe he can get a job and start contributing?

I can understand BOTH parents supporting through uni / colleague. But HE’S decided to take a year off, he’s an adult, therefore he needs to learn the value of money and stand on his own two feet.

Maintenance stops in the September after the child’s last term in school.

No way can she believe working part time allows her to avoid a fair portion of support unless she has primary kids why can't she work???? She's taking him for a ride!!!

There's nothing she can do once DC reaches 18 courts cannot enforce support for any adult unless they are special needs.

And no CM ends the month they have ther last day at school NOT September. Even the CMA stop it to then and can calculate to a specific date in a month so final month is not even paid in full.

There's nothing she can do it your SO decides not to pay, and why should he, child needs to learn to be independent sounds like she is using it as an excuse to screw your SO over. Please don't let him back down to her. Its women like her that give single mums such a stereotype as lazy money grabbers

Every other woman works to boost their income so no reason she can't!!! She needs to get some self respect
