"Lawsuits/Disputes" is a general category on Avvo for people who have general questions about lawsuits or disputes. It's a catch-all category.

Personal Injury Lawyer
On AVVO it's a category where you can list your question if it doesn't seem to fit in any other specific category, like Landlord/Tenant, Car Accident, etc.
