In addition to the litigation costs, there were also fees for hiring a lawyer. Lawyer fees could vary greatly. Typically, attorney fees for a civil lawsuit ranged from four thousand to thirty thousand. Although it wasn't mandatory to have an attorney to file a lawsuit, having a professional lawyer could significantly increase the probability of winning. Otherwise, a layman going to court could be easily misled by the opposing counsel and lose.

In total, the cost of filing his lawsuit was about eight hundred thousand.

He wouldn't actually lose money; he might even make a small profit.
