Courtney Love is heading to court in a bid to recoup the millions of dollars allegedly looted from her late husband Kurt Cobain’s estate.

The Nirvana frontman, who killed himself in 1994, left at least $30 million in cash and a huge portfolio of property for his relatives, including Love and the couple's daughter Frances Bean.

But some employees hired to maintain the late rocker's estate are said to have drained it, using the identities of Cobain, Love and Frances Bean to buy and sell real estate across the U.S.

Singer Love, who has publicly battled drug addiction, now plans to claw back the cash and property through the courts - and has pledged to use the case to help people whose homes have been repossessed.

Her lawyer, Rhonda J. Holmes, tells the New York post column PageSix, "Courtney noticed the money was gone when there wasn't any left. It's no secret she struggled with substance-abuse issues, but in the last year she's taken a more serious approach to sobriety and started noticing things were wrong."

The Hole rocker has hired a team of private investigators and forensic accountants, and has even recruited the help of federal authorities to identify the thieves and reclaim the cash.

Holmes adds: "I have never seen such greed and moral turpitude... We will be filing civil cases within the next 30 days. There are many, many millions missing. We've only been able to track down $30 million, but there is more. And then there is the real estate.

"There is now a web of homes which were bought, flipped and used to launder money - up to $500 million worth. Any of the property we can get back will be donated to people who have lost their homes in foreclosures."
