This guide states the law governing access to civil courts for people constrained by cost, language, or disability. Part 1 covers filing fees, the federal in forma pauperis statute, the screening that accompanies it, prisoner-specific limits, and state waiver systems. Part 2 covers the constitutional cases that supply a floor beneath access and the separate question of appointed counsel. Part 3 covers language access under the Court Interpreters Act, Title VI, and state programs, including scope, quality, and the procedure for requesting an interpreter. Part 4 covers disability access under ADA Title II and Section 504, the modification standard, and the coordinator and grievance structure. Part 5 covers the costs that survive a fee waiver, including service, transcripts, experts, and taxable costs. Later parts address remote appearance, self-representation, corporate parties, appellate access, and the record a party must build when a request is denied.
