I'm very sorry if you're in the process of going through a divorce! That can be an incredibly painful time!
Not to be discouraging, but it's hard to think of frugal and divorce in the same sentence. Lawyer's fees, court costs, outrageous childcare costs, and the cost of furnishing, heating/cooling two places instead of one make divorce so much less frugal than marriage. It's one of the top three reasons why people go bankrupt.(Major illness and job loss are the other two.)
If you fit their guidelines, sometimes Legal Aid will help you. It doesn't hurt to look into it.
I've had two very good friends go through it, and I would say their biggest mistakes were getting bad lawyers and signing things when they shouldn't have just to get it over with. This cost them A LOT more money in the long run. (Going back to court to fix things can be expensive and frustrating.)
It's such an emotional time and it's hard to know what is best when you're just trying to make it from one day to the next. Take it one day at a time. Sometimes it can feel like you'll never breathe again, but you will!
If you have kids, get a sensible custody agreement. Try as hard as you can to put your feelings for your soon-to-be-ex aside ASAP for the kids. Custody battles for spite are a waste of money and only line the pockets of lawyers and emotionally scar kids. Consistency with both visits and support is very important to kids.
Hang in there!
