if a lawyer has been disbarred in one state is it possible to be admitted in another state?

Most states will recriprocate with suspension of a lawyer, so if a lawyer is disbarred in one state, most other states would probably not admit the lawyer. Often if a lawyer is licensed in more than one state and is suspended in one state, the other state will suspend the lawyer also.

I would not rule anything out. However, It would be exceedingly difficult to be admitted after being disbarred.  First of all, it would be impossible to conceal the fact of being disbarred from the application process. The state where admittance is being sought would defer to the state where the lawyer was disbarred. The lawyer would probably have to go to the state where disbarred and seek a waiver which essentially would allow him to apply for reinstatement in that state were he a resident and otherwise eligible for reinstatement. This would have the salutary effect of giving him a green light to apply in the other state.
