an attorney advised me at one point that even if you do own 100% of a company, if personal and company finances are intertwined, that could be a large risk to the separate, limited liability status of your company.
in other words if you used your company money to pay for personal stuff or vice versa, "they" can come after your personal money if the company can't pay.
Yes, because you can't hide behind the corporate veil of limited liability if you yourself are mixing business with pleasure and other things personal, so to speak.
So creditors and other stakeholders are going to be able to pierce the corporate veil, which means you are personally liable. Just like if you were a general partner in a partnership.
