Biography & Early Wealth Journey
De Causans' case centers on his ancestor, Guillaume II de Wurtemberg-Urach, who he says should have been crowned the rightful Prince of Monaco after the reign of Louis II. But Guillaume II was German, and in 1911 a law was passed that allowed Louis II to adopt his illegitimate daughter Charlotte Louise in order to ensure her succession.
That law was later determined to have been illegal, and now the Count de Causan is seeking financial damages of about $401 million from France. According to his attorney Monsieur Jean-Marc Descoubès, this quirk in the line of succession is far from being a simple matter of title or even of political power, since were it not for that decision "[h]is fortune would be out of proportion with what it is today."

Primary Income Streams & Multi-Million Contracts
Albert II, Prince of Monaco today (pictured above) is worth around $1 billion, but it isn't he whom de Causans blames for the situation, nor is he included in the lawsuit. As he explains:
"I thought it was the Grimaldis' fault, but then I found out it was the French state that caused this dramatic turnaround for us."
The $401 million in damages is said to be about how much de Causan's family has lost in the wake of losing their place in the throne's line of succession.
