Princess Tessy of Luxembourg is representing herself at the High Court in London in her divorce trial.
Princess Tessy’s marriage to His Royal Highness, Prince Louis Xavier Marie Guillaume of Luxembourg has come to an end after a ten year marriage.
After their marriage when he was just 19, Prince Louis renounced his succession rights to the throne.
Speaking outside court, the princess did not explain why she had chosen to represent herself.
In court, she addressed Mr Justice McDonald in English.
The Family Division trial lasted several days.
Mr Justice McDonald is expected to make decisions on how money and assets should be split in the near future.
He said Prince Louis and Princess Tessy, both 32, could be named in media coverage of the case, but ruled to stop the reporting of financial and personal details.
