This guide covers name and gender marker changes from the petition through the last record update. Part 1 distinguishes the routes by which a name changes and explains why the court order is only one of them. Part 2 sets out the petition, the disclosures every state requires, the grounds for denial, and the hearing. Part 3 covers publication, waiver, and sealing. Part 4 covers minors and the best-interests analysis that governs a contested change. Part 5 covers gender marker changes document by document. Part 6 sets out the agency sequence and its dependencies, which cause most of the delay in practice. Parts 7 through 10 cover the credit file, the records people forget, employment and licensing, and the criminal and fraud limits. Part 11 addresses cost and fee waivers, and Part 12 collects the errors that recur.
