The conclusion is kind of unsatisfying. I feel like a better resolution would have been for the half-dragon to have either gotten inheritance from his father, or some inheritance from the foreign royal family. All that for a single ring, even if it's an heirloom, just doesn't quite sit right after all he's been through.
If they needed the half-dragon to end up in debt, just have it so neither side has anything to give him; the mother was disinherited; and the father blew all his wealth on keeping up the princess' lifestyle, so the brother literally has nothing to give (and was ashamed because of how undragon-like that is), for example.
Plus, for all the hyping up of the legal stuff, with her citing random legal violations when threatening others and such, she didn't really seem to do much 'lawyery stuff' and instead just proved a connection between the mother and father (which is more detective-like than layer-like).
It would have been cool if they were using the real laws of now (or historical laws) and applying it to these fantasy situations - like how would parentage been proven before DNA testing for cases like these? How much of the inheritance should a bastard child, born out of wedlock, receive? Does Dragon society even care about marriage, and if not, doesn't that mean him being a bastard child is legally unimportant once the blood relation is proven?
Not to mention all the discrimination cases she should be able to start because of her client being rejected solely because of his race.
But overall is was enjoyable, and I wouldn't mind this getting picked up, especially if they do zero in more on the legal stuff.
