My ex-girlfriend's story of her divorce was similar. It was an extremely hostile, nasty divorce with custody at stake and accusations of mental health issues on both sides, but she and her husband managed to agree on one thing: after many months of legal fighting, they agreed that they were being systematically bled by the lawyers. The lawyers were concocting reason after reason to drag everyone into court and file ungodly amounts of paperwork. They were nowhere close to being divorced, and it looked like it would take years.
Her lawyer (an older, grandfatherly gentleman) treated her in an apparently very caring manner, repeatedly calling her at night to see if she was okay and discuss minor issues of the case, always managing to get her upset and then spend a couple of hours comforting her and giving her advice. Then she found out he was billing for that time, so she stopped answering his calls after five o'clock.
Her husband had a similar realization that the case had turned into them against the lawyers, so they agreed to simultaneously fire their lawyers and hire new ones. Then they went back to hurling neglect, abuse, and mental illness accusations at each other and fighting over custody. Years later, having lived in separate states for many years, they can barely stand to talk on the phone three or four times a year to coordinate on the daughter going to see his side of the family. But in the middle of a nasty divorce, they managed to agree about the lawyers.
