I am moreso asking if this would be ok in nature under HSA tax rules. I can always reimburse my ex-wife with regular funds and reimburse myself with HSA funds for the purpose of covering my portion of the qualified medical expenses. I just didn't know if it poses an issue that she is paying the direct bill to the medical provider. I have documentation of our agreement, as well as all of the copies of medical bills. The reimbursements can be traced to the penny.
