1) Shareholders are not liable for the corporation's debts, except for those they personally guaranteed, so if this is a corporation and you are a shareholder, you should not have to worry about any company debts.2) You can't become a shareholder without your consent, so if you never agreed to accept the shares, you did not. Indicate in writing to the attorney and any company officers, sent some way that you could prove delivery, that you never agreed to be come a shareholder and demand that they change their records. If despite that, they or anyone tries to insist for some reason that you did take the shares and you do not want to be considered a shareholder, you would have to bring a lawsuit against the company seeking a "declaratory judgment" (or court determination) that you are not a shareholder.
