Stevie Wonder filed a lawsuit on Thursday claiming his lawyer who died in 2011 duped him into signing a ‘forever’ royalties contract.

The 65-year-old music legend claimed that his longtime lawyer Johanan Vigoda took advantage of a blind man, according to an article on Thursday by TMZ.

Wonder in his lawsuit claimed that he was unaware of a clause in the contract that he signed at age 21 granting six percent of royalties ‘forever’ to Vigoda and his heirs.

Vigoda died aged 82 in November 2011 in Reno, Nevada after a short battle with pancreatic cancer.

After his death Wonder’s record company continued to make the royalty payments to Vigoda’s widow Susan Strack and Wonder claimed in his lawsuit that he didn’t realize the payments were being made until 2013.
