The Social Code IX (SGB IX) for the rehabilitation and participation of people with disabilities entered into force on July 1st 2001 and aims to promote the self-determination and social participation of people with disabilities.
It is divided into two parts. The first part (§§ 1 - 67) applies to all people with disabilities. The second part (§§ 68 - 160) regulates participation of people with severe disabilities. According to § 2 (2) SGB IX) , a severe disability is defined as a degree of disability of at least 50%.
In 2016, the SGB IX was supplemented by the Bundesteilhabegesetz (BTHG). The changes will be implemented in stages until 2023.
