What Is a Trust Fund for a Child?

A child trust fund is a trust that holds assets for a minor (or young adult) and releases money according to rules you set.

The trust fund has:

• Grantor: you (the parent/creator)

• Trustee: manages the money

• Beneficiary: your child

• Rules: when and how money is distributed

Best Trust Type for a Child (Most Families)

✅ Revocable Living Trust + Minor’s Subtrust (common “best” option)

This is often the cleanest approach for parents because:

• you keep control while alive

• you can update the terms as life changes

• it can avoid probate when funded

• it allows you to include a minor’s trust section so your child doesn’t receive assets directly at 18

When an Irrevocable Child Trust may be used

Sometimes parents choose irrevocable options when they want stronger restrictions, but this can add complexity and may require professional guidance.

For most families: start with revocable living trust + minor rules.

The Two Biggest Decisions You Must Make

1) Who will be the trustee?

The trustee will control the assets and follow your rules.

Pick someone who is:

• responsible with money

• emotionally stable

• organized

• willing to follow instructions

Avoid choosing someone who is likely to “freestyle” with your child’s money or cause family conflict.

2) What are your child’s distribution rules?

This is where most “trust fund” value is created.

Best Age Structures (Examples You Can Use)

Here are popular options parents use (you can pick one and keep it simple):

Option A: Staggered Ages (most common)

• 1/3 at age 25

• 1/3 at age 30

• 1/3 at age 35

Why parents like it: avoids blowing it all at once and gives maturity time.

Option B: Education + Launch Support

Allow distributions for:

• tuition/training

• housing and healthcare

• first car (with cap)

• starting a business (with approval + cap)

Then full access later (ex: 30 or 35).

Option C: Needs-Based (trustee discretion)

Trustee can pay for:

• health, education, support, maintenance

• emergencies

• reasonable living expenses

This is flexible but requires a strong trustee.

Option D: No lump sums (income approach)

The trust pays:

• set monthly support

• plus approved expenses

• principal stays protected longer

Good for families who fear reckless spending.

What Expenses Should the Trust Be Allowed to Pay?

Common allowed categories:

• education/trade school

• medical/dental/therapy

• housing/rent support

• childcare (if your child becomes a parent)

• transportation

• emergencies

• “one-time launch help” (moving costs, deposits)

You can also put caps like:

• “up to $X per year”

• “trustee approval required”

• “no luxury purchases until age X”

Should You Use a Spendthrift Clause?

Many trusts include a spendthrift clause to add a layer of protection around distributions (often helps discourage creditors from grabbing future distributions, depending on state law and facts).

It’s a common add-on when building a child trust fund.

How to Fund a Child Trust Fund (The Step Most People Skip)

A child trust fund only works if assets actually go into it.

Funding can include:

• real estate (deed into trust)

• bank/brokerage accounts (retitle into trust)

• cash gifts (deposited into trust-held accounts)

• personal property (assignment + inventory)

• business interests (assignment/retitle carefully)

If you don’t fund it: your child may still end up in probate or court-supervised processes.

What If Your Child Is a Minor and You Die?

Without a trust, many states require:

• court-supervised guardianship/conservatorship

• restricted access to money until 18

• lump sum control at 18 (often risky)

A trust fund helps avoid that by giving a trustee authority to manage assets under your rules.

Common Mistakes Parents Make

❌ Naming a weak trustee “because family”
❌ No clear age rules (or too early)
❌ No education/health provisions
❌ Forgetting to fund the trust
❌ Not naming backups (successor trustees)
❌ Not telling anyone where the documents are stored
