guardianship is more powerful than custody. how do you know it was temporary? when will the guardianship end if it was temporary and how can you prove that? overturning a guardianship is not easy. if your mom has custody then you can petition the family court (in Indiana) to return custody to you. a guardianship is more complicated. either way I would talk to a family attorney to figure out what your rights are. depending on your daughter's age her testimony might help you a lot as well.
