Good question. If a corporation that you have an interest in as a shareholder cannot continue payments on a commercial lease where you did not sign a personal guarantee as to the lease, you can cease paying on the lease through your corporation and most likely you will not suffer and personal liability under the lease.However, to have a better idea of your situation, I suggest that you consult with a landlord tenant attorney who does commercial leases. The concern is that if your personal name is on the lease as well as your social security number, there is a chance that you may have signed the lease personally and be obligated under it individually.
