Michael Jackson's estate is suing the singer's former manager, claiming he lined his own pockets by persuading the pop superstar to sign unconscionable contracts in the final year of his life, according to The Sky News.

The lawsuit against Tohme R Tohme came after more than a year of wrangling between Jackson's estate and the former adviser who claims he's owed 15 per cent of the more than 310 million dollars collected by the estate since the singer's 2009 death.

The lawsuit the contracts involved a refinancing of Jackson's debt related to Neverland Ranch and a producer's fee that Tohme negotiated for himself for Jackson's series of planned comeback concerts in London.
