I left my husband after taking physical, emotional, verbal, and mental abuse from him almost 3 years ago now. He filed for divorce over 2 years ago but refuses to sign the final divorce papers so I could get him out of my life once and for all and not be connected in any way to each other. What is my next step to do to get our divorce finalized without having to hire an attorney? He won't sign the final divorce papers because he don't want to pay me any of his precious monthly pention check.

We need to know where you are located.
Does the divorce agreement say he has to pay you part of his pension? Was this something you two decided on your own?
You may have to file for divorce on your own, but if you want support from him, you are going to have a very difficult time without a lawyer. No one HAS to hire a lawyer, and you could file without one if you just want a very basic divorce and there are no children.

Go back to the court that issued the divorce papers and ask that they be finalized by default.

(Yes, I agree with Scott, you don't have to file yourself.)
