Cobain filed for divorce from musician Isaiah Silva in March.
Frances Bean Cobain's soon-to-be ex-husband isn't going down without a fight.
Isaiah Silva, whom Cobain married in 2014, has requested spousal support from the 24-year-old daughter of Kurt Cobain and Courtney Love.

According to documents obtained by ET, Silva, 31, is requesting $25,000 a month -- a total of $300,000 a year -- in alimony. Silva, formerly of the band The Eeries, claims that he put his career on hold after marrying Cobain.
The documents go on to state that Silva has gone into debt after Cobain reneged on her promise to pay for private school and housing bills for his 7-year-old daughter from a previous relationship. Silva states that in addition to losing financial stability, his daughter has traumatically lost a step-mother, and therefore also requests funds for his daughter's visits to therapy.
Silva's request also mentions Cobain's lavish lifestyle as well as the estate of Cobain's late father, Nirvana frontman Kurt Cobain, reportedly valued at $450 million, as proof of her wealth and ability to provide alimony payments. A hearing has been set for Sept. 7.
Divorce documents obtained by ET in March state that Cobain was open to paying spousal support, but was adamant about protecting her father's estate. So far no prenuptial agreement has surfaced.

Cobain has been focusing on herself since filing for divorce, which has brought her closer to her mother.
Love couldn't help but gush about her daughter earlier this month, when Cobain posted a short video of herself covering Jimmy Eat World's "The Middle" to Instagram.
"Your father is very proud of this as am I baby," the former Hole singer wrote. "I love you to the moon and back ❤❤ #proudmommy."
