Mega Millions lottery winner Holly Lahti has let her estranged husband off the hook. She's waived her right to child support and medical expenses for their two daughters.

EXCLUSIVE DOCUMENTS: Idaho Lottery Winner Waives Child Support

RadarOnline.com has learned that an Idaho judge last week ruled Joshua Lahti no longer has to pay support, a decision which was fully supported by his rich ex, who won a $190 million Mega Millions jackpot this past January.

Joshua Lahti has spent years battling the law, now it looks like the law is going to help him collect $40 million!

Lahti’s estranged wife Holly Lahti won half of the $380 million Mega Million jackpot on January 4, and because the couple is not divorced yet, Joshua, who has a record of 20 arrests, likely will be entitled to half of her winnings. Her share of the jackpot should be $80 million after taxes if she takes it as lump sum.

RadarOnline.com broke the story Thursday that both Holly and Joshua, from Rathdrum, Idaho, have been arrested and produced the first photo of them -- mug shots.
