Is there any way to legally divorce someone yourself if your estranged spouse refuses to sign the papers?

This is awful. A relative of mine agreed to divorce his wife over a YEAR ago. He moved out, but he refuses to sign the divorce papers. I feel so sorry for his wife. She wants to get on with her life, but she can’t because he won’t finish things up. He won’t even call a lawyer.

Is there ANYTHING she can do to get out of this by herself?
