Desperate help needed for legal fees to save our family!

My wife and I are in desperate need of help with legal fees. Her ex inlaws have been dragging us through court for 29 months. We have paid over 40000 in legal fees already and we are 3 months from our final trial. Now we have to pay the still owed amount of 18000 to our attorney's or they won't represent us any more.

The ex I laws are trying to take custody of our 3 children. They got their son my wife's ex to say he was unfit so they could intervene in the case because they knew he wouldn't get what THEY wanted. Only one of the children is biologically theirs. They have threatened us that they have a million dollars to fight the lawyers. We don't have that kind of money. My wife works everyday just to turn her pay check over to her attorney every week. I work everyday to make sure the bills are paid and the kids have everything they need. We haven't even been able to buy ourselves new clothes or anything because to us it the kids who matter and making sure they are happy and well taken care of is the most important thing in our lives.

Any help would be appreciated. Thank you for your time and consideration in helping us.
