Quick answer: To change your child’s name on the birth certificate in Singapore, apply to ICA online before your child turns one. You can do this only once, and the other parent must consent. The fee is S$33, plus S$18 for a new digital birth certificate. ICA takes about 3 working days. After the first birthday, the birth record cannot be changed, so parents use a deed poll instead.
Want to change your baby’s name in Singapore? Apply to ICA online before your child turns one. Maybe a grandparent picked a new name, or you changed your mind. This guide explains the time limit, the steps, the documents, the fees and the deed poll.
The One-Year Rule for Changing a Baby’s Name
The rule comes from the Registration of Births and Deaths Act 2021. Section 21 lets a parent ask to change the name in the birth register. The application must be made within one year after the child’s birth.
ICA sets these conditions:
- Your child was born in Singapore.
- Your child is under 1 year old.
- The name has not been changed before.
That last point matters. You get one change only, so choose the new name with care.
Once you submit the LifeSG birth registration, you cannot edit it there. A name change through ICA is the only way to change the name in the first year. Still deciding on a name before you register? Read about registering a birth in Singapore first.
Alteration of Child’s Name: Who Can Apply and the Consent You Need
ICA calls this process the “Alteration of Child’s Name”. Only a parent or legal guardian can apply. The other parent must agree to the change, if that parent is named on the birth certificate.
You show this agreement with a consent letter signed by the other parent. What if the other parent will not sign? Then you need a court order. It must give you full control to change the child’s details without the other parent’s consent.
A common problem we see is a custody order issued overseas, in another language. ICA cannot read it as it is. An English translation of a foreign custody order shows the officer what rights the court gave you.
How to Change Your Child’s Name on the Birth Certificate Before Age One
The whole process is online. Here are the steps:
- Agree on the new name with the other parent.
- Get the signed consent letter, or the court order.
- Open ICA’s online form at go.gov.sg/ica-acn.
- Fill in the child’s and parents’ details.
- Upload the documents.
- Pay S$33 for the application and S$18 for the new certificate.
- Wait about 3 working days for ICA’s decision.
- Download the new digital birth certificate.
When ICA approves the change, it cancels the old digital birth certificate. The new one shows the new name. Delete or mark old printouts, so nobody uses them by mistake.

Documents Checklist
Have these ready before you open the form:
| Document | Who needs it |
|---|
| NRIC of both parents | Singapore citizen and PR parents |
| Foreign passport and FIN card | Foreign parents |
| Consent letter signed by the other parent | All cases where the other parent agrees |
| Court order giving you full control | Only if there is no consent letter |
| Other supporting papers | Only if ICA asks |
Check that each name on the papers matches the parents’ passports. A small spelling difference can lead ICA to ask for more proof.
ICA asks for an official translation of any document that is not in English. If the other parent writes the consent letter in Chinese or Hindi, get it translated first. Many parents choose a notarised version of a parent’s consent letter. A notary’s seal is one of the forms ICA accepts.
Fees and Processing Time to Change a Child’s Name
ICA’s fees are fixed and cannot be refunded:
| Item | Fee |
|---|
| Application to change the child’s name | S$33 |
| New digital birth certificate | S$18 |
| Total | S$51 |
You pay online by credit card, debit card or PayNow. ICA usually processes the request in 3 working days, if all documents are complete. Missing papers can add days, so upload everything at once.
After Age One: Changing a Name by Deed Poll
After the first birthday, the law does not allow the birth register to change. You can still change the name your child uses, though. You do it with a deed poll.
A deed poll is a legal paper that formally changes a person’s name. A Singapore lawyer, called an Advocate and Solicitor, prepares and witnesses it.
For a child under 21, the parents sign the deed poll. Both parents or guardians should sign. If only one parent signs, that parent must be present when the change is registered. They must also declare that both parents agreed.
Was your child’s name changed overseas, in a foreign court or registry? Then that foreign paper must be read in English here. A translation of a foreign name change order keeps the old and new names exactly as written.

What the Deed Poll Does and Does Not Change
A deed poll changes the name your child uses from now on. It does not change the birth certificate. The birth certificate will still show the old name.
So you will use both papers together. Show both whenever an office needs to link the old and new names.
After the deed poll, update your child’s other records:
- Passport. Apply for a new passport that shows the new name, and include the deed poll.
- Identity card. A child aged 15 or above has an IC. Apply online for a replacement IC. The fee is S$60. The steps are the same as for any IC particulars update with ICA.
- School and medical records. Give them a copy of the deed poll.
For a minor’s IC, both birth parents must consent to the name change. If only one parent consents, ICA needs a court order.
Foreign Children: Change the Passport First
Is your child a PR or a foreigner? Then the passport usually comes first. ICA asks PRs to update the name in their passport before they update their IC.
The passport is issued by your home country. So contact your embassy or high commission in Singapore. Ask what papers they need for a child’s name change.
Some embassies may want the Singapore birth certificate in their own language. Then translating a birth certificate for an embassy helps its staff match the names.
Common Mistakes to Avoid
These are the slip-ups we see most often:
- Waiting past the first birthday. After that, only a deed poll can help.
- Applying without consent. ICA needs the other parent’s letter or a court order.
- Using a self-made translation. ICA wants an official translation from an embassy or notary, or one that a notary has notarised.
- Choosing in a rush. You can change the birth record only once.
- Keeping old printouts. The old certificate is cancelled after the change.
What Happens Next
After ICA approves the change, download the new digital birth certificate. Save it on your phone and computer.
Then update the name with your child’s doctor, childcare centre and insurer. Does your child have a passport? Apply for a new one with the new name before you travel.

Frequently Asked Questions
How do I correct a spelling mistake on my baby’s birth certificate?
A spelling error made at registration is a correction, not a name change. E-mail ICA at ICA_RBD@ica.gov.sg. Explain what needs to be corrected and attach supporting documents.
Can I change only my baby’s surname?
Yes, while your child is under one. The surname is part of the name, so the same ICA form, consent rule and one-change limit apply. After the first birthday, a surname change needs a deed poll.
How much does a deed poll cost for a child?
The law does not fix a price for a deed poll. Each law firm sets its own fee. Ask two or three firms for a quote before you choose.
Can I register the birth first and add the name later?
Yes. The law allows a birth to be registered without a name. A parent can then apply to enter the name within seven years after the birth. This is different from changing a name, which must happen before the first birthday.
Will ICA update the parents’ names on my child’s birth certificate if a parent changes name?
No. ICA does not update parents’ details on a child’s birth certificate after registration. Instead, show the parent’s deed poll with the child’s birth certificate when an office checks the new name.
Can we apply to change the name while living overseas?
The ICA form is online, so parents abroad can usually apply. Singapore embassies say the birth register can be changed for a child under 12 months. They ask parents abroad to contact them for the steps.
Conclusion
To change your child’s name on the birth certificate in Singapore, act before the first birthday. Apply online to ICA with the other parent’s consent and pay S$51 in total. You can do this only once, so be sure of the new name.
After age one, use a deed poll and keep it with the birth certificate. Is a consent letter, court order or foreign name paper not in English? Ask a Singapore agency that translates name records to prepare an official version first.
