A guardianship is awarded when:
Parents still have parental rights. They can ask for reasonable contact with the child.
The judge in court can end a guardianship if the parents become able to take care of the child.
Guardians can be supervised by the court.
An adoption is awarded when:
The parents' rights are permanently ended.
The legal relationship with the adoptive parents is permanent and is exactly the same as a birth family.
An adopted child inherits from his or her adoptive parents, just as a birth child would.
Adoptive families are not supervised by the court.
Foster case happens when:
The parents’ rights are temporarily transferred to the state but parents may be able to see the child if CPS grants permission.
A judge can end a foster care placement if CPS determines that the parent(s) can take care of the child or a relative/caregiver gets guardianship or adopts the child.
Foster parents are completely supervised and licensed by the state.
