It wasn't easy, but Frank Ocean finally got a judge to help him kill off someone very close to him -- Christopher Edwin Breaux ... as in the name Frank was given at birth, but is now ditching.
Frank's request for a legal name change got a judge's stamp of approval today in L.A.
As we previously reported ... Ocean filed legal docs a year ago to make the switch, but a judge put the brakes on the process until Frank cleared up some drivers license issues.
Breaux, born in Long Beach, CA, was 27. He died of severe anonymity and underappreciation.
