The dispute over the guitar has made headlines over the past two years, as it continued to be a point of contention in the divorce: Silva claimed that Frances gave it to him as a wedding present, which Frances denies.
Kurt Cobain's iconic 1959 Martin D-18E, which he played throughout Nirvana's legendary MTV Unplugged set, is no longer within the Cobain family, as daughter Frances Bean Cobain has left it to her ex, Isaiah Silva, in the couple's divorce settlement.
People confirmed Cobain will lose the guitar in her divorce settlement with Isaiah Silva, which was finalized Monday.
Frances, for her part, gets to keep the house she and Silva bought together and will not have to pay Silva spousal support.
Frances Bean Cobain, an artist whose mother is rocker Courtney Love, Wednesday Silva, lead singer for The Eeries, in an unpublicized ceremony on June 29, 2014, according to Cobain's divorce filing in early 2016.
Lee sued the city of Seattle and its police department in 2014 and is described by the courts as "a conspiracy theorist who believes that Mr. Cobain was murdered".
In her motion filed that same year, Frances Bean wrote that "Releasing these photographs would physically endanger me and my mother".
Earlier this month, Frances opened up to the Daily Front Row about what her late father would think of her own music. In court documents obtained by the site, Kurt and Courtney Love's only daughter filed a request barring Silva access from her father's estate which is valued at around $450 million.
Frances celebrated her first anniversary with new beau Matthew Cook in January.
