If the child you are seeking guardianship of is 17.5 years old, call the office to see if we can assist before registering for the clinic. Guardianship proceedings can take up to three months to complete. If the child is near or above 18 years old, then minor guardianship may not be appropriate for the situation. If you are concerned about a disabled child who may need an Adult Guardianship, see Adult Guardianship.
