Maintenance and extra's

Hi,

Not a mum, but believe in getting a broad perspective on pretty much everything (I do this with politics, health, work, etc lol).

I have a bit of a pickle, and would welcome your insight!

Divorced from ex-wife, now a little over 9 years ago. 3 kids:

Child1 has autism (undiagnosed), and receives Dla, he's going into year 11 next week.
2 other Children on spectrum too, but no benefits/diagnosis (Child2+3 are both 13)

I work full time, pay rent privately and look after my house. I have kids roughly 45% of the time - working out at around 170 nights a year, but also take on much of the admin load (appointments, forms, school stuff, etc)

I pay £350 maintenance a month (Private agreement, not CMS mandated), and also contribute 50/50 towards extra costs - trips, uniforms, hair cuts, glasses if they're over the voucher level, etc)

Ex receives Cb, UC and PIP. She'll also get the disabled child element of UC from my understanding.

I'm at a point where i'm unable to continue funding 50/50 of the 'extras' on top of the maintenance, rents have all gone up (£1,100 where I live now) as well as everything else, as we all know.

Would I be unreasonable to tell my ex that i'm unable to continue with this arrangement? We get along well, and are usually happy to help each other out if things come up (DIY stuff, or if i have to work until later etc) and I don't want to upset things, however I don't feel this is sustainable for me financially and believe that this should be covered comfortably by maintenance and child benefit?

Mods, if you feel this is better in a different category, please feel free to move it!

How does she get dla when undiagnosed is that how it works?

DLa (and PIP) are based on documented needs and issues, rather than diagnosis specifically

A diagnosis isn’t a requirement of DLA

Hi,

Yeah, I pay more than the calculator deems necessary

£16 more a month… CMS calculations are also the bare minimum so you’re currently paying the absolute minimum possible towards your children.

You need to come to a compromise with the mother of your children.

Hi

Thank you. That's why i'm here, to work out what would be reasonable. Compromise does work two ways however.

£350 between 3 kids wouldn't go far at all even if you are paying 50% of the extras. You can do a calculation on the CMS website to work out the minimum amount you need to pay.

Have you worked out how much maintenance you’d have to pay via cms?

Hi,

Yeah that's the amount that CMS would charge worked out via the online calculator but rounded up to the nearest £50. The CMS calculator works it out at £334 a month
