In the State of TX, I'm required to share 50% of the out-of-pocket medical expenses. I'm trying to find out what might be the best way for me to pay such expenses? I don't want to give it as cash, check, etc. and not (potentially) get credit for it, or have it become a point of contention or dispute in the future. Paying it via the TxSDU could mean that I get credit for extra payments. It's worth noting that my overpayment credit (from paying extra over the years) is in the thousands; as a result, the ex is a little sensitive about increasing that.What is the name of your state (only U.S. law)?
