If you set up, funded, and operated the corporation properly the corporation's creditors will not be able to pierce the corporate veil and reach into the shareholder's and officer's assets.
The converse is also true. If the corporation is a separate entity then the bank does not have the right to seize its assets without receiving a judgment first.
Regarding the safe deposit box, I have never heard of a case where a bank seized the contents of a safe-deposit box without receiving a judgment first. If you continue to pay the fee to rent the space, the contents of the safe deposit box cannot be touched.
I hope this information helps you Find. Learn & Save.
