TLDEF was founded in 2003 by Michael Silverman to advocate for transgender rights including health care and restroom access.[2][3]
In January 2024, TLDEF announced that they will be merging with the National Center for Transgender Equality to form a new organization, Advocates for Trans Equality. The merger is planned to happen by the summer of 2024.[4]
TLDEF's name change project pairs private attorneys with transgender clients and has helped about 1,500 transgender people change their names.[7]
Notable cases brought by the organization include In re Mathis, the successful 2013 petition of first-grader Coy Mathis to the Colorado Civil Rights Division for the right to use the restroom appropriate to her gender,[8] and Schawe-Lane v. Amazon, in which the U.S. Equal Employment Opportunity Commission found evidence of harassment and discrimination against a husband and wife couple at the Amazon distribution center in Hebron, Kentucky, currently pending in the United States District Court for the Eastern District of Kentucky.[9] The organization recently won rulings from the U.S. Equal Employment opportunity against Walmart in two cases: Robison v. Walmart,[10] and Bost v. Walmart (also in litigation in North Carolina federal court).[11] As a result, the Human Rights Campaign suspended Walmart's rating in its Corporate Equality Index.[12]
