We have my husband's son's sister. we got a Guardianship paper notarized. But tried to enroll her in collage and the said it had to go through court. or papers signed by her mother. We called her and asked her to fill papers out. She said yes but now she wont answer her phone and we don't know where she is. So we need to know if we can still go though court now that she is 18? or is there another way to get a pell grant?
