One possible plot could be that Harry discovers some corrupt practices within the wizarding legal system. As a lawyer, he decides to take on the powerful figures involved. He uses his knowledge of the Dark Arts and the laws of the wizarding world to build his cases. Along the way, he meets new characters, some of whom are trying to stop him while others are eager to help. His Gryffindor courage drives him forward, and he has to balance his personal life, including his relationship with Ginny, with his fight for justice in the legal realm.
Well, perhaps Harry Potter, in the guise of Loki, uses his trickery skills in the wizarding legal system. He could be defending those wrongly accused of using dark magic, like using his shape - shifting abilities to find evidence that others can't.
One possibility could be that Harry Potter hires a lawyer to deal with the legal mess left behind by the wizarding wars. For example, he might need help in getting proper compensation for the damages done to the wizarding community. The lawyer could be a Muggle - born wizard who has knowledge of both worlds' legal systems and uses that to fight for the rights of those affected.
One possible plot could be that the lawyer helps Harry deal with the legal aftermath of the Battle of Hogwarts. There might be issues regarding the rebuilding of the wizarding world, and the lawyer could ensure that Harry's rights and the rights of his friends are protected during this process.
The plot could involve a situation where Harry Potter hires a goblin lawyer to fight against the unfair treatment of house - elves in the wizarding world. He might want to use legal means to change the laws regarding their servitude. Since goblins have their own ideas about fairness and legality, the goblin lawyer could be crucial in formulating a legal strategy for this noble cause.
One common theme is the clash between the traditional wizarding legal system and new ideas. For example, a fic might explore how a young wizard or witch, trained in modern legal thinking, tries to reform the archaic laws of the Ministry of Magic. Another theme could be justice for the underrepresented, like house - elves or half - bloods. In these fics, the lawyer character would fight for their rights. Also, there's often the theme of mystery and intrigue as the legal cases might involve dark magic or secret societies within the wizarding world.
The fanfic could center around Harry's life outside of the main events of the books. For example, it could explore his summer holidays in more detail. He could be spending time in the Muggle world and using his magic in creative ways to solve normal, everyday problems. He might use magic to help his neighbor fix a broken fence without the neighbor realizing it was magic. This would add a new dimension to his character and show how he can adapt his magical abilities to different situations.
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.
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.
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.
One possible plot could be that Harry Potter is hired by Sherlock Holmes to help with a case that involves dark magic. Harry uses his knowledge of the wizarding world to uncover clues that Sherlock couldn't find with just his deductive skills.
