How to Set Up a Trust Fund for Your Children: Step-by-Step Guide
How to set up a trust fund for your children: trust types, step-by-step setup, costs, choosing a trustee, distribution ages, 2026 tax rules and the mistakes parents make.
Parents who want to set up a trust fund for your children usually have the same worries: who controls the money, at what age the kids receive it and how to keep it safe from taxes, creditors and bad decisions. A trust answers all three because it lets you write the rules in advance and appoints someone to follow them. This guide explains how to set up a trust fund for your children in six steps, compares the main trust types, shows what each costs, covers the 2026 federal tax numbers and lists the errors to avoid. It focuses on the United States, and details differ by state.
Quick Answer: How Do You Set Up a Trust Fund for Your Children?
- Define your goal and name the child, plus a backup beneficiary.
- Choose the trust type: revocable, irrevocable, testamentary, 2503(c) or Crummey.
- Name a trustee and at least one successor.
- Write the terms: when and for what purposes the money is released.
- Sign the document and obtain a tax ID if one is needed.
- Fund the trust by moving assets into it.
LegalZoom stresses that a trust “isn’t active until it’s funded,” so the last step is the one that makes the earlier ones count.
What Is a Trust Fund for Your Children?
A trust fund for your children is a legal arrangement in which a trustee holds assets and manages them for a child under rules you set. LegalZoom explains that the trustee invests the money, keeps records and pays it out according to those terms, acting in the beneficiary’s best interest. Unlike an outright gift, a trust fund for your children lets you stage the release of money, link it to goals such as education or housing and add protection against creditors, depending on the structure.
Types of Trust Fund for Your Children
The sources describe overlapping options, summarized here.
| Type | Key features | Source |
|---|---|---|
| Revocable trust | You can change or cancel it, but the assets remain in your taxable estate | LegalClarity |
| Irrevocable trust | Terms are locked, assets generally leave your estate and creditor protection is stronger | LegalClarity, LegalZoom |
| Testamentary trust | Created through your will after death, so it goes through probate | LegalZoom |
| Section 2503(c) minor’s trust | Irrevocable, for children under 21, gifts can use the annual exclusion, but the child may withdraw at 21 | LegalClarity, Legal Shield |
| Crummey trust | Irrevocable, you set the distribution age, each gift needs a withdrawal notice, typically giving the child about 30 days | Legal Shield |
| Section 2503(b) income trust | Income is paid out regularly while principal can wait, and only the income part qualifies for the annual exclusion | Legal Shield |
| Special needs trust | Supports a child with a disability while protecting eligibility for benefits such as SSI and Medicaid | LegalClarity, LegalZoom |
Trust or Custodial Account (UTMA/UGMA)?
LegalZoom notes that UGMA and UTMA accounts are not technically trusts. UGMA covers financial assets only, while UTMA also allows real estate and other property. They cost less and are simpler, but the child receives full control at the age set by state law, which LegalClarity and Legal Shield say is typically 18 or 21. If you want to decide the age yourself, a trust is the better fit.
| Feature | Trust | UTMA/UGMA account |
|---|---|---|
| Who sets the release age | You | State law |
| Setup | Document plus funding | Simple account opening |
| Setup fee | Attorney or platform fees | None, per The Hive Law |
| Control after the age limit | Follows your terms | Child has full control |
Step-by-Step: Setting Up a Trust Fund for Your Children
Step 1: Define the Purpose
Legal Shield says the purpose shapes every later decision. Decide whether the money is for school, a first home, a start-up fund or general security, and whether you want to name a contingent beneficiary, as LegalZoom suggests.
Step 2: Pick the Trust Type
Legal Shield calls a revocable trust the usual starting point, while LegalClarity notes that irrevocable trusts offer stronger creditor protection and can remove assets from your estate. A child with a disability points toward a special needs trust.
Step 3: Appoint a Trustee and Successor
Choose someone with sound judgment who will be around for decades. LegalZoom lists family members, friends and professional or corporate trustees as options and tells parents to name at least one successor. Legal Shield adds that parents often serve as trustee of their own revocable trust.
Step 4: Write the Distribution Rules
LegalZoom says terms can tie access to an age, to specific expenses such as education, housing and medical costs, or to a staged schedule. The age section further down gives examples.
Step 5: Draft and Sign
Draft the trust to meet your state’s rules. LegalClarity recommends gathering names, Social Security numbers, addresses and asset details, signing with notarization and obtaining a tax ID: revocable trusts generally use the grantor’s Social Security number, while irrevocable trusts need an EIN.
Step 6: Fund the Trust
Funding means retitling accounts, recording deeds and changing life insurance beneficiaries, according to LegalClarity. Legal Shield warns that an unfunded trust is just a piece of paper and that many parents slip on this step. Review the trust at least every three years, as Legal Shield advises.
How Much Does a Trust Fund for Your Children Cost?
Sources quote different ranges, so the table keeps them separate.
| Source | Figure |
|---|---|
| LegalClarity | Attorney-drafted trusts typically cost $1,000 to $6,000; corporate trustees generally charge 0.5% to 1.5% of assets a year and often require $300,000 or more |
| The Hive Law | General trust attorney fees of about $2,000 to $5,000 or more |
| Legal Shield | A few hundred to a few thousand dollars, depending on type and state |
The Hive Law breaks its range down by type.
| Type | Attorney fee (The Hive Law) |
|---|---|
| Revocable living trust | $1,000 to $3,000 |
| Irrevocable living trust | $1,500 to $5,000 |
| Special needs trust | $2,000 to $5,000 |
| Crummey trust | $1,000 to $3,000 |
| Testamentary trust | $1,000 to $3,000 |
| 529 plan, Coverdell ESA, UGMA/UTMA | No setup fee |
LegalZoom says online platforms are cheaper than traditional legal services and that complex trusts cost more. LegalZoom and Legal Shield both sell legal services, so treat their framing as marketing.
How Much Money Do You Need?
Legal Shield says there is no legal minimum to fund a trust. The Hive Law suggests a starting contribution of about $100 to $500, with 529 plans accepting initial contributions as low as $25 and Coverdell accounts capped at $2,000 per year per beneficiary. It also states that the average trust fund for middle-class families runs from $50,000 to $200,000, an undated figure from a single law-firm blog.
Choosing the Trustee
The trustee owes a fiduciary duty to the child, manages investments prudently, decides on distributions and typically provides annual reports to beneficiaries, according to LegalClarity.
| Trustee option | Advantage | Consideration |
|---|---|---|
| Parent | Knows the child and costs less | Not available if the parent dies or is incapacitated |
| Relative or friend | Personal knowledge of the family | May lack financial expertise |
| Professional or corporate | Experience and continuity | Fees of 0.5% to 1.5% and often a $300,000 minimum (LegalClarity) |
LegalZoom puts choosing the wrong trustee first on its list of mistakes, so name a successor and review the choice if circumstances change.
At What Age Should Children Receive the Money?
LegalClarity says families often choose ages 25 or 30, or milestones such as finishing college, and that planners increasingly advise against distributions before 25. It offers a sample staggered schedule.
| Age | Release |
|---|---|
| 25 | One-third of the trust |
| 30 | Half of the remainder |
| 35 | The rest |
Under a 2503(c) trust, the child can withdraw at 21 no matter what you prefer, so choose that type only if you accept it.
2026 Tax Rules for a Trust Fund for Your Children
LegalClarity and Legal Shield give the following 2026 numbers.
| Item | 2026 figure |
|---|---|
| Federal estate and lifetime gift exemption | $15,000,000 per person ($30,000,000 for married couples, per Legal Shield) |
| Annual gift exclusion | $19,000 per recipient, or $38,000 for married couples |
| Trust income taxed at 37% | Starts at $16,000, versus over $626,000 for an individual (LegalClarity) |
| Irrevocable trust return | Form 1041 if gross income is $600 or more |
| Kiddie tax | First $1,350 of unearned income is tax-free, the next $1,350 is taxed at the child’s rate, and amounts above $2,700 are taxed at the parent’s rate |
LegalClarity adds that the kiddie tax generally applies to children under 19, or under 24 if full-time students. Because a trust reaches the top bracket at a far lower income than an individual, ask a tax professional how this applies to your case. Also be careful about naming a trust as a retirement account beneficiary, since LegalClarity warns it can accelerate taxes.
Alternatives and Add-Ons
Some parents combine a trust with simpler accounts. LegalClarity recommends a 529 plan for education funding, and The Hive Law lists Coverdell education savings accounts and custodial accounts alongside trusts. A trust can then handle larger or more flexible goals.
Mistakes to Avoid
- Choosing the wrong trustee. LegalZoom ranks this first.
- Not funding the trust. Assets left outside it do not receive its protection.
- Writing vague instructions. Say exactly when and why money may be released.
- Skipping updates. LegalZoom lists failing to update the trust after major life changes as a common mistake.
- Forgetting the age limit on custodial accounts. The child gets full access when state law says so.
- Ignoring taxes. Trust tax brackets are compressed and can raise the bill.
Checklist Before You Sign
- List the assets you plan to place in the trust.
- Choose the type and the release ages.
- Name a trustee, a successor and a backup beneficiary.
- Get written quotes and compare an attorney with an online platform.
- Confirm the tax ID and filing requirements.
- Retitle assets and keep proof of the transfers.
- Calendar a review at least every three years.
