O.J. Simpson's son is being sued for allegedly moving into his late father's home without permission.

Malcolm LaVergne - an attorney who serves as special administrator of the late sportsman-turned-actor's estate - has filed a lawsuit against Primary Holding LLC, which he says is owned and operated by Justin Simpson, claiming the 36 year old has gone back on a deal made over the house.

According to TMZ, the lawyer told how Primary Holdings purchased the house where the 'Naked Gun' star was living when he died of cancer in April last year in a deal where the firm would keep the property in order to protect O.J.'s financial interests and shield the abode against creditor claims.

But after the controversial NFL star - who was famously acquitted of killing his ex-wife, Justin's mom Nicole Brown Simpson, and her friend Ron Goldman in the 1990s - passed away, his son moved into the house and claimed because he owns Primary Holdings, the property is also now his and refused to leave or pay the estate back for the alleged payments his dad had made in the past.

Malcolm insisted O.J. had never intended for the house to be made separate from the estate and the sportsman had been making the house payments all along.

He noted Justin is still living in the house, despite owning a home nearby, and wants it as his own, in direct contradiction to his father's will.

In the months following O.J.'s death, the estate has sought to sell off some of his belongings in an attempt to liquidate his assets and py off creditors.

And last month, Malcolm revealed he is hoping to sell off O.J.'s stash of pornography from his 2008-2017 stint in Nevada state prison, where he served time for memorabilia theft.

O.J.'s estate faces a $500,000 tax lien from the State of California and at the time of his death, he still owed millions of dollars to Nicole and Ron's families from their 1997 wrongful death lawsuit.

A civil court had found him liable for the pair's deaths and though the original judgement was $33.5 million, interest on the unpaid debt has reportedly caused it to escalate to around $100 million.
