I lost this story and I really would like to reread it.
Harry was Tonys son, (I think he discovered it when he read some letters of his mother?) and for some reason he had to become a american citizen (some thread because of the MoM?).
Anyway, because it would last some time if he only contacted the american ministry he got in contact with Tony so that Tony would get his custody.
I remember clearly that Harry had a lawyer with him and that he declared that there was no interest in Tonys money because Harry is well off himself.
- I'm fairly sure that it was on ao3
- it was after the Battle of Hogwarts
- I think Tony did not know about magic (maybe later, but maybe I'm mixing stories together)
- I'm not sure if this story was complete
I'm searching for hours and hopefully someone here can help :)
