A guitar used by Kurt Cobain during Nirvana's legendary MTV Unplugged show in 1993, and reportedly insured for $1 million, has become the subject of dispute in his daughter's divorce.

Frances Bean Cobain denies claims by her estranged husband, Isaiah Silva, that she gave him the guitar as a wedding present, and says she wants him to return it to her. 

In this country, assets that have been gifted to (or inherited by) one party are often treated differently to other assets, and that party is allowed to keep them. However, this very much depends on the couple's individual circumstances, so it is important to get detailed legal advice in these sorts of situations.
