hoping for some advice so apologies of o type this clumsily.
when exw and dp divorced they agreed maintenance privately and dp pays quite happily every month. the figure set at the time was based on have the kids every other weekend, they agreed a figure slightly less than csa guidelines (only by £8/week) so that dp could help out towards additional costs like school trips etc. we also buy all school shoes, clothes for here, presents, give them pocket money and dp pays into their savings accounts every month.
due to the increased cost of energy bills etc we are struggling so dp has reduced the amount he pays into the kids savings accounts. his ex has hit the roof and is demanding that it was part of the discussion and agreement to pay less than the csa guidelines. we have been through all the mediation paperwork and the agreement has been noted as less so he can pay for trips and holidays and big presents at Christmas. nothing is mentioned about the savings account. we also now have the kids for more nights than at the time maintenance was agreed and so in reality he is paying about £50 a month more than he has to according to csa and that's before the £40 a month into their savings accounts and £10-15 a month pocket money depending on whato chores they complete, so it's more like £100 over.
now whilst the extra money for us would be really helpful he has no intention of reducing her payments and neither would I let him. but she is demanding that the saving account money goes up which we genuinely can't afford it.
I have been through the paperwork over and over and copied the sections for her and printed out the csa calculator to show what he should be paying based on the current contact agreement so he can discuss it with her but I don't know of we are being unreasonable.
what do we do? if we put it back up then the kids will lose out because there won't be money to pay for school shoes (£60 between them yesterday) or for school trips. dsd's have already cost us £200 this year and dss wants one that costs each parent the best part of £700 next year. I know she will flip of we refuse to pay dp's half and I have gone back to work to help out with saving for it (and yes I know technically it's not my place but he really wants to go).
Any tips?
