My bad, I guess I didn't realize the purpose of this thread was validation
Perhaps it will clear things up for you if I provide a brief summary. You know one of those TLDR thingies for people who have difficulty with absorbing, processing and retaining large amounts of information.
1- I've been paying a substantial amount child support for the better part of 10 years to my exwife who has kept the lions share (as is her legal right), and it's even worse the past few years because my daughter isn't even living with her since she moved out of state and has never visited her mother during this time.
2- I'm down to the last 4 support payments (as of this morning the 1st of the month) and those payments total about $8k.
3- I've been thinking for a while about making that last lump sum payment for next year all at once, just to get it over with and to start next year with a clean slate, free of legal obligations to my exwife. I have contacted an attorney about this matter and have been advised that with her written permission I can do that, without risking it being viewed as a "gift" and being liable for those 4 months of child support in the future should she decide to file a motion saying it wasn't paid pursuant to the court order.
4- My daughter recently told me she wants to get a car and she was trying to figure out the best way to go about doing that, at which point I told her I was considering making a lump sum final payment to her mother, and how that would make the funds available immediately for her use if her mother was willing to provide them to her.
5- She expressed her concerns that she wasn't seeing most of the support money and it would be doubtful that she would get what she needed from her mom even if it was a large sum at once.
6- After we discussed it, she contacted her mom first to go over the idea, she didn't get very far so she asked me to contact her mom which I did, and that didn't go anywhere either.
7- We are now on plan B which assumes ex is not interested in assisting her daughter with the car purchase because she intends to continue to keep the lions share for herself, which she is legally entitled to do, and there's nothing I can say or do because I have no control over her. This plan B includes me assisting her financially with purchasing a vehicle which of course I am under no obligation to do, as well as continuing to pay her post age 21 college expenses, also which is done because I want to not because I have to.
I hope this helps clear up your apparent confusion.
