This appeal concerns a post-judgment motion to amend a judgment to add ten entities as judgment debtors based on an alter ego theory. The trial court granted the motion, finding the entities were the alter egos of appellant Gaggero and were set up to avoid creditors. On appeal, Gaggero argues the trial court erred in applying an outside reverse piercing doctrine, and that there was insufficient evidence the entities were alter egos or were created to defraud creditors. Gaggero also contends the motion was barred by laches and that affirming the ruling could threaten estate planning in California.
