1) Being on disability has *nothing* to do with your obligation to pay debts. That your source of income is disability does not absolve you of the debt, though it does make it harder for the creditor to collect from you (many types of disability payments cannot be garnished, removing one of their tools to collect).2) If the debt was a *corporation's* debt, however, not yours personally, then are not responsible for it even if you were the corporation's sole shareholder (sole owner). The entire point of a corporation is to protect the owners (share- or stockholders) and employees from personal liability for business debts and obligations.
