Exh and I have agreed to split expenses for kids' clubs/lessons according to our income. The ratio is 80:20 - of our combined income, I make 80%, he makes 20%.
This means that I pay the lions share of lessons which I am fine with. (btw we are not in UK and this agreement is standard in our country)
Recently it came out that he never registered DC in one of the lessons I've been paying for and that he said he was taking DC to. I found this out via DC, asked ex, who confirmed he'd "never found a lesson time that worked".
It's about 200 quid in all that I've paid, via a top up to the monthly maintenance, over about 6 months. So, just subtracted that from the amount paid this month. I've notified ex, attached the spreadsheet showing the calculation etc. Asked that if he does sign DC up again, to send me documentation, to prevent the same happening in future.
He will be furious but I do think that part I'm NBU. It is what it is, he took money that he never even signed up on lessons for, now I need it back.
What I am wondering is this - DC does one other lesson with me that has slightly variable costs month to month. This is the first year he's done it, so I'm not sure yet what the average p/m cost is.
So I've estimated it, at the end of the year, will reconcile all the receipts and if I actually owe ex some money due to the actual cost being less, I'll pay it back on the next payment.
That's reasonable as well, isn't it? Or is it U to require ex to notify me of he registers before I cough up again... if I am not sure on one of the expenses we both pay into.
Ex has form for arguments over money and how controlling I am etc... just wanting to gird my loins before he comes back on that... it's important also to just say that I am controlling about the money in the sense that ex consistently protested that he could not manage to calculate or administer anything related to what money needs to be paid for DC, so I do it all and try to be as meticulous and transparent as possible because I don't want to be slapped with a surprise solicitor's letter for back pay in the future...
