Frances Bean Cobain has been forced to give up rock legend father's iconic guitar as part of a divorce settlement.

The 1959 Martin D-18E, which Kurt Cobain played in Nirvana's famous 1993 MTV Unplugged performance, will be awarded to Frances' ex-husband Isaiah Silva, TMZ reports.

Courtney Love and Kurt Cobain's only child wed Isaiah in 2014. They had been married for less than two years when she filed for divorce.

The prized instrument has been a central issue in the couple's legal battle for years.

Last year, Frances filed court documents requesting Isaiah return the guitar, which he claimed she had gifted to him.

Frances' mother Courtney refuted Isaiah's story at the time, telling TMZ the instrument was "a treasured heirloom of the family".

"It's not [Isaiah's] to take," Love said.

"We're very close, and [Frances Bean] never planned on doing that."

The settlement did grant Frances sole ownership of the couple's property, and also saw Isaiah denied a request for US$25,000 spousal support per month.

Frances celebrated her first anniversary with new beau Matthew Cook in January.

She was just one year old when her father died in 1994.
