Soulja Boy Sues Ex-Manager, Claiming He Took Advantage

According to TMZ, the 21-year-old rap star (real name DeAndre Way) recently filed a lawsuit against ex-manager/lawyer Philip Ransom, claiming he took advantage of a naive teenage, coercing him into signing away a percentage of his earning ... forever.

In court docs, Soulja Boy says he was persuaded into signing multiple contracts when he was just starting his career, which he claims were "unconscionable, oppressive, and unjust."
The contracts included a management agreement that gave Ransom 5% of Soulja's income ... forever ... relating to work the rapper completed while Ransom was his manager.

In another, it allegedly gave 50% of all Soulja's music copyrights to his record label -- a deal the rapper now claims is "commercially unreasonable" and "contrary to music industry custom and practice."
Ransom denies the allegations, according to TMZ, and has filed his own legal docs that claim Soulja Boy still owes him money from their time together.
