In Indonesia, persons with disabilities are protected by Law No. 8 of 2016 that contains 22 rights that should be obtained by persons with disabilities. A document analysis approach was carried out to identify the language rights of persons with disabilities in the Law text. The transivity of Halliday's Systemic Functional Linguistics was applied to describe the characteristics of the law text . We found that the language rights for persons with disabilities are contained in articles 7, 19b, 24c, 31, 41, 82, 85, and 88, namely the right to be free from stigma, the right to public services, the right to expression, the right to communicate and obtain information, the right to justice and legal protection, educational rights, religious rights, and cultural and tourism rights. We also found that the relational process is the dominant transivity of the clauses of the articles on language rights for disabilities.
