Can you please help me?

Harold and Dorothy own all of the shares of Ace Corporation. Robert, Ace's landlord, sued Ace for unpaid rent. Robert received a $10,000 judgment against Ace. When Robert tried to collect on the judgment, he discovered that Ace Corporation had no assets. He then discovered that Harold and Dorothy no longer operate Ace Corporation. They now operate Optimus Corporation as the only shareholders. Harold and Dorothy had no assets in their names. However, upon further investigation, Robert discovered that Optimus had numerous assets. He reviewed the financial documentation, discovering that Optimus pays for Harold and Dorothy's mortgage, medical bills, and grocery bills. Can a court pierce the corporate veil? Discuss.
