Thank you so much, TaxGuyBill!  Father and Mother are not talking to each other much in the nasty divorce and Father will definitely not let Mother take any PTC as he paid 100% for it (although I actually don't know the details of the Child Support agreement and the divorce is not finalized). Thanks for letting me know Father can actually claim 100% but I have to input the 1095-A allocation in Mother's tax return as well. Trying not to get letters from IRS.

Mother is not as organized and Father doesn't want his daughter to go without health insurance. Mother only has coverage for herself. Kids are not double-covered.

Both Mother and Father are self-employed so buy individual insurance through the Exchange (Father) or Off-Exchange (Mother). I had to help Mother straightened her situation. In 2016, she was partially in the same 1095-A until Father kicked Mother out of the plan.
