I moved from Gainesville, FL to Winter Haven in November 2007. I have been trying to get my former wife to change the exchange point ever since. She knows I can not afford to get a lawyer, because I am still paying for hers from the divorce. Is there paperwork I can file on my own to the court system to get this changed?

You can try to do it yourself, but if it requires her to drive further to meet the original court order, I wouldn't hold your breath.

You moved by choice... its not your ex's problem and a court is unlikely to order more requirements on her unless you can nail down a solid reason for the move.

You decided to move, and now you have to move further. What is the issue, I doubt you can get them to move the point unless the other parent will just agree
