Attorneys are not uniform on their fees. When initiating contact with an attorney, request an estimate on the fee. Though perhaps necessary, guardianship means the loss of freedom and choice for your child. To minimize the loss, you might think about a limited guardianship. A limited guardianship is tailor-made for your child, and is limited to only those areas truly required.
Limited guardianship provides the protection needed, but minimizes the loss of independence.
The answer is no. Indiana law does not allow for a contingent guardian, so the appointment of a successor cannot be completed in advance of an existing guardian's death or resignation. The law says that the court will appoint a successor guardian for a protected person if a successor is needed. However, the court can only do so if it knows that a successor guardian is needed. It might never learn that you have died and, as a result, that a successor is needed.
