Many parents assume their children will automatically inherit their assets if something happens to them. In California, it is rarely that simple when minor children are involved.
Children under 18 generally cannot legally manage inherited money or property on their own. Without proper planning, California law may require an adult to manage those assets on the child’s behalf until adulthood. Depending on the circumstances, that may involve a court-supervised guardianship, a blocked account, or another custodial arrangement under California law.
For families in La Jolla, creating a trust is often an important part of estate planning for minor children because it allows parents to decide how assets should be managed and when children should receive them.
Why Leaving Assets Directly to Minor Children Can Create Problems
If a child inherits assets without a trust or other planning arrangement in place, the court may need to appoint someone to manage the funds until the child becomes a legal adult. While these protections are designed to safeguard children, they can also create delays, legal expenses, and added stress for families already dealing with a difficult situation.
There is another concern many parents overlook: in many cases, absent trust planning or another legal arrangement, a child may gain control of inherited assets at age 18.
For some families, that may not align with their long-term goals. Parents often prefer to provide financial support gradually rather than handing over a large sum at a young age.
This is one reason trusts are commonly used in California estate plans.
How a Trust May Help Protect Your Children
A trust allows you to create instructions for how assets should be managed and used for your child’s benefit. Instead of assets passing directly to the child, a trustee manages the funds according to the terms you establish.
Depending on your family’s needs, the trust may allow money to be used for:
- Education expenses
- Medical care
- Housing and living costs
- Extracurricular activities
- Long-term financial support
You can also decide when distributions occur. Some parents choose to stagger distributions over time rather than giving a child complete access to assets at age 18.
For many La Jolla families, this approach offers more flexibility, structure, and long-term financial protection.
Parents with minor children often also include guardian nominations in their estate plans. A guardian is the person nominated to care for the child personally if both parents are unavailable, while a trustee manages inherited assets. These roles may be filled by the same person or by different individuals, depending on the family’s preferences.
Choosing the Right Trustee Is an Important Decision
The trustee is responsible for managing trust assets and carrying out your instructions. This role carries significant responsibility.
A trustee may need to:
- Manage investments
- Keep financial records
- Make distributions properly
- Handle certain tax filings
- Act in the child’s best interests
Trustees in California owe fiduciary duties to beneficiaries and are generally required to act prudently and in accordance with the trust terms.
Because of these responsibilities, choosing the right person matters. Some parents select a trusted family member, while others consider professional support depending on the complexity of the estate.
At Hsiao Law, we often encourage families to think carefully about who has the time, judgment, and financial responsibility to manage these duties over many years.
Estate Planning Is About More Than Wealth
One common misconception is that trusts are only for wealthy families. In reality, many parents benefit from planning even if they do not consider themselves high net worth.
Life insurance policies, retirement accounts, savings, and a family home may represent substantial assets that deserve protection and clear instructions.
We regularly meet parents who simply want peace of mind knowing their children would be cared for if the unexpected happened.
Attorney Amy Hsiao takes time to explain these concepts in straightforward language so families can feel informed instead of overwhelmed. Clients throughout La Jolla appreciate the firm’s approachable style, bilingual English and Mandarin services, and commitment to making estate planning more understandable.
