I have, in various contracts and other issues.
It all depends on the nature of the issue, I suppose. Are you suggesting that attorneys commonly would handle business related litigation in another state for which they are not admitted?
BTW...Im not an attorney, but a business owner.
Generally, yes. You get local counsel to make court appearances for you if you can't get admitted pro hac vice, but many lawyers (especially at larger firms) will handle lawsuits and/or commercial transactions in other states.
