You may have found savings in a child’s name, need money because of a change in family circumstances, or be approaching their 16th or 18th birthday. It is easy to assume that being a parent, registered contact or the person who paid in gives you authority. Getting that wrong can delay access to the money or mean acting without the right legal authority.
Taking ownership of a child’s savings depends on the product, the child’s age and your legal role. A parent does not automatically own money saved for a child or have a right to withdraw it. The account type—Child Trust Fund, Junior ISA, Premium Bonds, bank account or trust—determines who can manage it, when the child takes control and which documents may be required.
ISA or premium bonds: who controls the money?
The account type provides the first answer.
Start with the product name, not the family relationship. A named parent, a registered contact and a legal guardian can each have authority to deal with paperwork, but none of those labels alone proves ownership of the savings.
Does the child legally own the money?
For a Junior ISA and Child Trust Fund, the child is the beneficial owner. This means the money is theirs in substance, even though an adult may have opened or managed the account.
No. A registered contact can manage a Junior ISA or Child Trust Fund on the child’s behalf, but does not own the money. Their role is administrative rather than one of ownership.
Which product permits withdrawals?
Withdrawals before 18 are normally barred from Junior ISAs and Child Trust Funds, except in narrow situations such as terminal illness or certain court-approved cases. Premium Bonds bought for a child also have their own National Savings and Investments rules.
| Product | Who owns the money? | Who manages before 16? | Normal access point |
|---|
| Junior ISA | Child | Registered contact | 18 |
| Child Trust Fund | Child | Registered contact | 18 |
| Premium Bonds for a child | Usually child | Responsible person | Provider rules apply |
| Children’s bank account | Check mandate | Child or adult, by terms | Often earlier than 18 |
| Trustee or designated account | Trust deed or account terms | Named trustee | Trust terms apply |
The labels used on children’s savings accounts describe different things. The legal owner is the person named as account holder under the provider’s contract, while the beneficial owner is the person entitled to the money. In a Junior ISA or Child Trust Fund, the child is normally both the intended beneficiary and the beneficial owner, even when an adult is the registered contact. A responsible person has a similar administrative role for Premium Bonds for children. Parental responsibility or legal guardian authority may help an adult prove they can give instructions, but it does not make them the owner of the savings.
For a children’s bank account, always read the account mandate: an account in a parent’s sole name but designated for a child can have a very different legal position from a trustee account governed by a trust deed.
At 16 and 18, control is not access
At 16, a child can usually take over management of a Junior ISA or CTF; at 18, they can normally withdraw or transfer the matured money. Managing means giving instructions, not breaking the lock on the savings.
Child’s savings route by age
Under 16
Adult operates where terms allow.
16 to 17
Child can usually become contact and manage a CTF or JISA.
18+
CTF or JISA matures. The young adult controls withdrawal or transfer.
Can a 16-year-old manage a junior ISA?
A 16-year-old can normally become the registered contact and make management choices. They may receive statements, change providers and decide whether a Junior ISA stays as cash or investments, subject to provider processes.
Why is CTF money locked until 18?
The Child Trust Funds Act 2004 created the CTF as long-term savings for the child. At 18, it matures and can be paid out, moved to an adult ISA or left in an adult ISA arrangement offered by the provider.
What happens to child premium bonds?
Premium Bonds for a child are subject to National Savings and Investments rules, which determine who can manage them and when the child can take control.

Separation, care and death change the proof needed
A family change does not itself transfer account control.
A separated parent with parental responsibility may be able to become the registered contact, but the provider will assess its records and evidence. It is not a race to change the name first.
What proof does a new guardian need?
The proof required depends on the child’s circumstances and the provider’s process. A new guardian may need to provide evidence of their relationship or legal authority before the provider will change the registered contact or trustee.
Tax and benefit checks before moving money
Do not rely on this general guide if a court order, deputyship, formal trust deed or safeguarding restriction controls the savings. Get provider-specific help and, where there is a live dispute or risk to the child’s money, legal advice before requesting a withdrawal or transfer.
Before asking a provider to change control, gather the product reference, the child’s full name and date of birth, proof of your identity and address, and evidence of your relationship or authority. Depending on the case, that evidence may include a birth certificate, adoption order, special guardianship order, court order, grant of probate or letters confirming a local authority’s role for a looked-after child. Ask the provider for its own process before sending originals, because its requirements for a new registered contact or trustee can differ.
Where parents disagree, do not assume that changing the contact details settles the dispute: the provider may pause instructions or require agreement, further evidence or a court direction. A replacement adult should also confirm whether there is an existing trust deed, restriction or safeguarding note before attempting a transfer or withdrawal.
Tax depends on where the money came from as well as the account wrapper. Interest, dividends and gains in a Junior ISA or Child Trust Fund are tax-free, but interest in an ordinary child’s savings account may be taxable income of the child. The special HMRC £100 rule matters where a parent gives money to a child: if the income arising from that parent’s gifts exceeds £100 in a tax year, the income from those gifts is generally taxed as the parent’s, rather than the child’s. Gifts from grandparents and other people are not caught by that specific rule.
For Universal Credit, capital genuinely belonging to a dependent child is not normally treated as the parent’s capital, but money moved into a child’s name while a parent still controls it may be examined. A young person claiming in their own right after 18 should check how their own savings affect their claim.
Frequently asked questions
Can a parent take money out of a child's savings?
A parent can withdraw only if the account terms permit it and the money is used for the child’s benefit. Junior ISA and Child Trust Fund money is normally locked until 18, while an ordinary bank account depends on its mandate.
Can I take over my child's junior ISA at 16?
No, a parent does not take over a Junior ISA at 16 because the child can usually take over management. The child still cannot normally withdraw the money until their 18th birthday.
Can I withdraw my child's child trust fund online?
A Child Trust Fund cannot normally be withdrawn online before age 18. At 18, the young adult must complete the provider’s identity process before withdrawing or moving it to an adult ISA.
Do I have to declare my child's savings?
A child usually pays tax on their own savings interest, but parental gifts can trigger HMRC’s £100 rule. Junior ISA and CTF interest and gains are tax-free, so they are not declared as ordinary savings income.
First identify the product and check whose name, or whose trust role, appears on the account.
The essentials:- A parent’s name on an account does not automatically mean they own the savings.
- Junior ISA and Child Trust Fund money generally belongs to the child and remains locked until 18.
- At 16, management can pass to the child without giving them withdrawal rights.
- After separation, bereavement or a care change, ask the provider for its evidence list before acting.
