This kind of happened to me i left my son with my mother while i went to florida to help out a relative while i was there she filed that i had abandoned him too make a long story short i pretty much got forced to sign over guardianship. I stayed in contact with my son and mother and did all the motherly things for him. So when i thought i was settled i went to terminate guardianship.All i did was type up a petition to terminate guardianshipand have int notarized, its best if you can get the childs father to sign one too and have it notarized. The things i was asked in court was if i had a home for him which i did, and how i would support him i didnt work at the time i was a student but my fiancee had a fulltime job and they took that into consideration. And if the reasons the guardianship had been placed where no longer an issue. My mom tried to make it hard for me too but the judge only wanted to here if there were real reasons I shouldnt have him and there were not any her vindictiveness worked against her. Hope this helps you.
