I'm looking into becoming a caregiver to a friend that doesn't have a place to stay. My friend is 17 years old and I plan on letting her stay with me until she finds a new place to live after becoming 18. Do i need to fill in some forms? If so where do i get them? I have approval from her legal guardian but haven't spoken to her biological mom yet, do I need her approval as well? Please give me some advice or answers.
