Does a Parent Still Have Power of Attorney When a Child Turns 18 in Kansas?

You may have spent years scheduling your child's appointments, helping manage finances, and making important decisions on their behalf. Once your child turns 18 in Kansas, however, being their parent no longer gives you automatic legal authority to make decisions for them. If your adult child has the capacity, they can choose to give you authority through a power of attorney. If they cannot, another legal arrangement may be necessary. 

Our Kansas City estate planning lawyer helps people prepare for the legal changes that come with adulthood. The right approach depends on what your child can manage independently, where support is needed, and whether a power of attorney or another legal arrangement fits those needs. 

Parental Authority Generally Ends at 18

Kansas generally considers a person an adult at age 18. The Kansas statute defining the period of minority provides that minority extends to age 18, with an exception for certain people age 16 or older who are or have been married. 

This change can be easy to overlook when your child's day-to-day life remains much the same. Your child may still live with you or rely on you for practical support, but the parent-child relationship itself does not give you power of attorney over an adult child. 

A power of attorney is authority that the adult child, as the principal, grants to another person through a written document. If your child can create a valid power of attorney, they decide whom to appoint and what powers that person receives. 

An Adult Child Can Give a Parent Power of Attorney

Your child can choose you as an agent if they have the capacity to create a valid power of attorney. This allows you to assist with specified matters without transferring all decision-making authority away from your child. 

A financial power of attorney can authorize an agent to handle financial, property, or other matters described in the document. Depending on its terms, a durable financial power of attorney can remain effective if the principal later becomes disabled. A power of attorney can also be drafted so that the granted authority becomes effective only on a specified future date, event, or condition. 

Kansas separately recognizes durable powers of attorney for health care decisions. These documents may authorize an agent to make specified health care decisions and obtain medical information. Under the Kansas health care power of attorney statute, an agent's health care powers generally take effect when the principal's impairment is determined by the attending physician unless the document provides otherwise. 

For families considering estate and special needs planning, this distinction matters. A power of attorney can preserve an adult child's decision-making rights while giving a trusted parent authority to step in where the document permits. 

HIPAA and FERPA Authorizations Can Preserve Access to Information 

A power of attorney is not the only document families may need to consider when a child turns 18. An adult child who wants a parent to continue receiving certain private information may need to provide separate authorization. 

A HIPAA authorization can allow health care providers to disclose specified protected health information to a parent or another designated person. This can be useful when an adult child still wants a parent involved in appointments or medical matters but can still make their own health care decisions. 

For a child attending college, a FERPA consent may also matter. Once a student turns 18 or attends a postsecondary institution, rights under the Family Educational Rights and Privacy Act generally transfer to the student. A student can provide written consent allowing the school to disclose specified education records to a parent. Certain exceptions may permit disclosure without consent, but parents should not assume they will automatically retain access to college records. 

These authorizations do not give parents general decision-making authority over an adult child. Instead, they can address specific information-access issues that often arise once a child reaches adulthood. 

Power of Attorney Depends on the Adult Child's Capacity

A power of attorney depends on the adult child’s ability to create the legal arrangement. It should not be assumed that every young adult with a disability either can or cannot execute one solely because of a diagnosis. 

This is especially important for families of children with intellectual or developmental disabilities. Turning 18 does not automatically mean that guardianship is necessary. The relevant question is what decisions the young adult can make, what assistance could help, and whether less restrictive arrangements can meet their needs. 

That analysis is especially important under Kansas's current guardianship law, which took effect January 1, 2026. The law expressly recognizes supportive services, technological assistance, supported decision-making, protective arrangements, and other less restrictive alternatives when determining whether guardianship is necessary. 

Guardianship May Be Necessary When Other Options Are Not Enough

A court-appointed guardian may be appropriate when an adult cannot meet essential requirements for physical health, safety, or self-care because of limitations in receiving and evaluating information or making or communicating decisions, even with appropriate support. 

Under the Kansas standard for appointing an adult guardian, the court must find the statutory requirements by clear and convincing evidence. The adult's identified needs must also be unable to be met through a protective arrangement or another less restrictive alternative. 

The law also limits guardianship to the authority the adult actually needs. A Kansas court may not establish full guardianship when a limited guardianship, protective arrangement, or other less restrictive alternative would adequately meet the person's needs. 

Financial affairs are addressed separately through conservatorship. Kansas courts may appoint a conservator when the statutory requirements for managing or protecting an adult's property or financial affairs are met. Depending on your child's circumstances, guardianship, conservatorship, a less restrictive alternative, or a combination of planning tools may be appropriate.
