If an attorney is disbarred in one state and has two other state licenses, is he disbarred in those states too?

Disbarment is usually reciprocal and automatic in other states of admission. Your friend will need to check with authorities in CA. He may be able to sit for the bar but admission is doubtful. If he really wants to try, he should hire counsel at the earliest opportunity.

If he does not report his disbarment to the other states, they likely will have grounds to disbar him as well, and perhaps they will based on his current disbarment.

Mr. Ilmanen is correct. If you are disbarred, or suspended, or convicted of a crime, you must report it to all state bars to which you are admitted and they may take disciplinary action as well (although ti may not be automatic, although tn the case of a felony conviction, it may be as in certain states like NY). It is very doubtful the attorney will be admitted in states where he has not yet passed the bar exam and filled out a complete application disclosing the disbarment, I doubt the attorney will get admitted, even if he is allowed to sit for and pass the bar exam (in some states like NY, the character and fitness committee review happens only after one has successfully passed the bar, Then even non criminal issues of character may be considered (I recall one attorney locally having problems because of a "road rage" incident. It doesn't have to involve legal matters.

I believe that most states require licensees to report their disbarment. I'll move this to ethics for you.
