A child turning 18 is a milestone many families celebrate. It also creates an important legal transition that parents often overlook. In Texas, once a child becomes a legal adult, parents generally no longer have automatic authority to access medical information or make healthcare and financial decisions on their child’s behalf.
At Bromlow Law, PLLC, we help families prepare for these life changes with practical estate planning tools designed to support both independence and peace of mind.
Why This Transition To 18 Matters
Even if your child still lives at home, attends college, or relies on you financially, the law treats them as an adult at age 18.
That can create unexpected challenges during emergencies. For example, healthcare providers may be limited in what they can share with family members under federal privacy laws. Financial institutions may also restrict account access unless proper legal documents are in place.
For many families, these issues do not become obvious until a stressful situation occurs.
What Documents Should Texas Families Consider?
Every family’s needs are different, but several planning documents are commonly reviewed once a child becomes an adult.
Medical Power of Attorney
A medical power of attorney allows your adult child to designate someone to make healthcare decisions if they become unable to make or communicate those decisions themselves.
This document can help families avoid confusion during medical emergencies, especially when a child is away at school, traveling, or living independently.
HIPAA Authorization
Federal privacy laws protect adult medical records, even from parents.
A HIPAA authorization allows healthcare providers to share medical information with designated family members or trusted individuals. Without written authorization, parents may have difficulty discussing treatment details or receiving updates during emergencies.
Durable Financial Power of Attorney
A durable financial power of attorney can authorize a trusted person to manage certain financial matters, depending on how the document is drafted.
This may include handling:
- Banking matters
- Bill payments
- Insurance issues
- Housing or tuition-related concerns
For college students and young adults starting independent financial lives, this document can provide important flexibility if unexpected situations arise.
Should an 18-Year-Old Have a Will?
Many people assume wills are only necessary later in life. However, young adults may already own vehicles, bank accounts, investment accounts, or digital assets.
A simple will can help clarify wishes and may help simplify the estate administration process for family members.
This milestone can also be a good opportunity for parents to review their own estate plans. Beneficiary designations, trusts, and guardianship provisions for younger children may no longer reflect the family’s current circumstances.
Beneficiary Designations Often Need Updating
One issue families frequently overlook involves beneficiary designations created years earlier.
Parents sometimes name minor children directly on life insurance policies or retirement accounts without revisiting those choices later. In Texas, financial institutions may require a guardianship or other legal arrangement before releasing inherited assets to a minor child.
As children become adults, families may want to reevaluate:
- Beneficiary designations
- Trust planning
- Asset distribution timing
- Financial management protections
Working with an estate planning attorney in Houston, TX, can help ensure these details align with your current goals.
