Remus Lupin could also be a candidate. He is a well - educated wizard and has a strong sense of right and wrong. Despite his lycanthropy, he has managed to survive in the wizarding world and has a lot of experience dealing with difficult situations. His calm and rational nature would serve him well as a private lawyer, especially when dealing with cases that involve prejudice and discrimination within the wizarding community.
Hermione Granger could be a great candidate. She is extremely intelligent, has a deep understanding of the wizarding laws (from all her studies), and is very determined. She could use her knowledge to fight for justice as a private lawyer. Her Muggle - born background might also give her an edge in dealing with situations that require a different perspective from the traditional wizarding view.
One possible plotline could be a private lawyer helping Harry Potter deal with the legal aspects of his inheritance from his parents. Maybe there are some dark wizards trying to contest it, and the lawyer has to use both magic and Muggle - like legal knowledge to fight for Harry's rights.
Luna Lovegood might be an unexpected but interesting choice. She has a unique perspective on the wizarding world. While she may seem a bit eccentric, her ability to think outside the box could be useful in a courtroom. She could come up with creative defenses for Harry, and her calm and dreamy nature might be able to sway a jury or judge in Harry's favor.
There were a few novels with the female protagonist being a lawyer that could be recommended, but they did not explicitly mention that the female protagonist was the cold type. Therefore, based on the information provided, I am unable to provide recommendations for the female protagonist's cold personal lawyer novel.
There could be an entirely new goblin character created just for this fanfiction. This goblin lawyer could be an outcast from the goblin community because of his more progressive views on wizard - goblin relations. Harry, seeing his potential, hires him to help with his legal battles that require a fresh perspective.
One potential private tutor could be a retired Auror. They would have a wealth of knowledge about the Dark Arts and how to combat them. They could pass on their skills in dueling and detecting dark magic to students like Harry Potter.
One possible plotline could be Harry using his knowledge of the wizarding laws, which he learned through his years at Hogwarts and his experiences with the Ministry of Magic, to defend wrongly accused wizards in a wizarding court. Another could be him trying to reform the wizarding legal system which he might find full of loopholes and biases.
Hermione Granger could be a common character. Given her intelligence and knowledge of the wizarding world laws (she's always reading), she could easily be imagined as a brilliant lawyer. She would use her quick thinking and vast magical knowledge to build strong cases.
Another theme is justice. Harry, being the hero we know from the original series, is always striving for justice in these fanfictions. He uses his legal skills to right wrongs and protect the innocent in the wizarding world. For example, in many of these stories, he defends those who are wrongly accused of using dark magic.
It could be Hermione. She's always been very book - smart and she could have decided to study law in the wizarding world. She already has a great understanding of the rules and regulations at Hogwarts, so it would be a natural progression for her to become a lawyer. And she would be very dedicated to helping Harry with any legal issues.
A lesser - known but very well - written piece is 'The Magical Law Offices of Harry Potter'. It delves deep into how the wizarding legal system might function and Harry's role in it. The author has created some really interesting legal cases and characters within the wizarding legal framework, making it a great read for fans of both Harry Potter and legal dramas.
