Shortly after separation and divorce my ex claimed she hired her mom for childcare. During the divorce proceedings I had gained evidence to believe that my ex was claiming her mother was providing childcare in order to funnel back money to herself. This was evidenced by bogus invoices with little to no detail, several payments that she "claimed" to have made to her mother for childcare on Venmo but did not match up correctly, fluctuating invoice prices even for when the kids were spending extended time with me, learning from my children that my ex mil doesn't watch them and has moved from the home...there is more details but this should suffice. I never agreed to my ex mil to provide childcare. At trial the judge was bombarded by my ex and her lawyer (family member) with hundreds of pages of smoke to present a horribly convoluted argument for what should have been a simple divorce (no assets besides a 401k) but children involved. Given the alloted time, mistakes from my lawyer, and what i believe was laziness and lack of attention to detail on the part of the judge, he did not address my concerns of the fraudulent childcare and simply ruled that we need to split childcare costs equally. After the divorce my ex continued to claim her mother was providing childcare but did not forward me invoices. During this summer I learned that my ex mil had moved and was no longer providing childcare. I had not received invoices for several months until today where my ex emails me and says she has found another childcare provider, her cousin and that payments will increase. She also tells me I owe her mom for the several months of non invoiced childcare and that it just so happens her mother was still providing childcare and was "kind enough" to let me ex make late payments on past childcare...i think this was in order for my ex to falsify her Venmo records again where she can claim to have made late payments to her mother when IMO my ex mil just funnels money back to my ex.

Hopefully this makes sense...has anyone dealt with something similar? Does anyone have some suggestions on how to handle this? I still have a few more years of kids needing childcare and this type of manipulation is killing me. My ex has already gone out and gotten plastic surgery and spent money on complete shit. Additionally she is playing a similar game with her boyfriend so alimony can stick around.
