Frank Ocean -- R.I.P. to My Homie ... Christopher Breaux Dies in Court

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.
