A man who won one of the largest lottery payments in U.S. history has filed a federal lawsuit against the mother of his child in an attempt to keep his identity concealed.

The man won a $1.35 million Mega Millions jackpot earlier this year after purchasing a lottery ticket at a gas station in Lebanon, Maine. He has sued his child's mother in U.S. District Court in Portland with a complaint that she violated a nondisclosure agreement by "directly or indirectly disclosing protected subject matter" about his winnings, court papers state.

Court filings state that the winner lives in Maine and the defendant lives in Massachusetts. The defendant has until Dec. 6 to respond to the lawsuit.

Records did not list an attorney for the defendant in the case. The winner's attorney, Gregory Brown of Knoxville, Tennessee, told the Portland Press Herald that neither he nor his client would discuss the lawsuit.

The complaint states that the winner and the defendant entered into the nondisclosure agreement shortly after the purchase of the winning ticket. The lawsuit states that the winner is seeking an injunction from a judge and at least $100,000 in damages.
