Hey there......as far as getting the paperwork from the hospital, I would definitely call the hospital and ask for it.
They may bring up the fact that you still have an outstanding bill so you may have to deal with that but you need to explain that you have no insurance or means of paying and that you are presently in need of the documentation to prove legally that you sought treatment after being physically abused by your husband as part of your divorce proceedings.
If you were to have a lawyer do this it is going to cost you money for the time they put into getting paperwork that you can get.....so doing it yourself will save you expensive legal fees.
And this will definitely be vital to your being able to keep custody of your children as well as the final determination in court as to what you are legally entitled to in terms of a divorce settlement.
Have you sought out counseling for yourself since being abused by your husband??? If so, documentation of that will be important as well.
Any emails, texts or documentation between you and your husband that could be used to show he had abused you is vital as well as any photographs that you may have that show the physical damage you incurred when he hit you.
As far as money he hasn't provided to you and the kids since you left, the courts will retroactively reimburse you whatever you are owed after they determine child custody and support and depending upon what state you live in, IF your husband has filed for divorce, he may have to pay your legal fees as well so it will be important for you to get good counsel so that you can get what you are legally entiltled to.
Sure you made some mistakes in your marriage but NO ONE deserves to be abused like you have been.
So collect whatever you can in terms of documentation to show why you needed to leave your husband for your safety as well as that of your children.
If at any time he harms or threatens you or your kids I would definitely file for a restraining order.....that's why having the paperwork from the hospital will be beneficial in terms of showing a history of his abuse. And make sure you get a police report next time....no matter what, keeping yourself and your kids safe is what is most important here.
Good luck with everything and please keep us posted with how things are going for you ~ Ivory
