A lawyer friend who has colleagues working in Family Law says they (the family lawyers) describe their practice as "Feelings Court". The law itself is a guideline, adherence to the rules for e.g. contents of filings is on a meh-effort basis (beyond things that are completely objective such as tax returns).
Yeah from what I've heard, family court is super wonky and does not follow the same standards that normal courts do, yet still have the same full force of law! It's crazy and makes me want to stay away from them with a 10 foot pole.
