Anna's legal fight to be recognized as a Romanov would give her access to all Romanov riches outside of Russia.
Explanation:
Anna Anderson was a woman who claimed to be Anastasia Nikolaevna, Grand Duchess of Russia, daughter of the last Russian Tsar, Nicholas II. Anastasia was murdered, as were her parents and siblings, but her remains were not found, which made many people believe that she had survived and that she was somewhere in Russia.
Anna claimed to be Anastasia and although we now know that this was a lie, she has maintained that statement for more than 60 years, but a conclusion has never been reached about it. If she could confirm that she was the Grand Duchess, she would be recognized as a Romanov and inherit all the family's wealth inside and outside Russia.
