Are there guidelines (time frames, reciepts) for submitting medical payments to the other former spouse?

The divorce decree itself should specify how the payments are to occur. Most agreements state that such payment be made within 14 days (or sometimes 30 days) of presentment of the medical expenses by the other party.

I would be highly suspicious of claims by an ex-spouse for payment of medical expenses when the ex-spouse refuses to provide receipts. A prudent person would send the ex-spouse a written letter outlining that they desire to pay as ordered, but that the ex-spouse must produce receipts as proof that such medical expenses were incurred.

You should consult with your divorce lawyer about this matter, as failure to pay the medical payments could result in a citation for contempt of court. If you no longer retain the services of your divorce lawyer, then seek out legal help on this matter. You may be able to find a local attorney at attorneypages.com.
