A more thorough explanation:

Term: Pro persona Definition: Pro persona means representing oneself in a legal case without a lawyer. It is a Latin term that means "for one's own person." It is also known as pro se or pro per. Example: John decided to file a lawsuit against his landlord for not fixing the leaky roof. He couldn't afford a lawyer, so he decided to represent himself in court. John filed the lawsuit pro persona. This example illustrates the definition of pro persona because John represented himself in court without a lawyer. He acted on his own behalf and filed the lawsuit without any legal assistance.
