The real Michael portrayed in "The Blind Side" says his adoption was a lie

 Retired NFL player Michael Oher has filed a petition claiming that his adoptive parents, Sean and Leigh Anne Tuohy, never officially adopted him. Oher’s story was the basis of the 2009 film The Blind Side. The petition alleges that the Tuohys enriched themselves by falsely claiming adoption and using Oher’s name and likeness without his consent.

… According to the filing, the couple tricked Oher into signing a document making them his conservators after he turned 18, which allowed them to secure deals for their biological children’s royalties from the film. Oher received no compensation. The petition seeks to end the conservatorship and stop the Tuohys from using Oher’s name and likeness.

… Oher says that when the Tuohys told him they loved him and wanted to adopt him, it filled a void in his life, but he later discovered that it was not true. He has petitioned a court in Tennessee to address the issue.
