AI image by LocalRankA Notary Public in Singapore is a senior lawyer individually appointed by the Board of Commissioners for Oaths and Notaries Public under the Singapore Academy of Law (SAL) to witness signatures, certify true copies and authenticate documents for use overseas, from powers of attorney to school certificates. That's different from a Commissioner for Oaths, who handles affidavits used only within Singapore. Since 2021, SAL has also been Singapore's competent authority for Apostille certificates under the Hague Convention. The law firms below each have an in-house Notary Public and describe notarisation, SAL apostille and embassy legalisation among their services — confirm exact requirements, and any mobile or after-hours option, directly with the firm.
1. Yuen Law LLC
Yuen Law LLC is a Clarke Quay law firm led by managing director Samuel Yuen, who is appointed as a Notary Public by the Board of Commissioners for Oaths and Notaries Public. The firm says it handles notarisation in-house: witnessing and attesting documents for overseas use, administering oaths and affirmations for affidavits and statutory declarations, and certifying true copies, before taking private documents through the two-step process of notarisation followed by Singapore Academy of Law authentication for an Apostille. Yuen Law advertises same-day notarisation during weekday office hours, and says it can arrange on-site appointments and coordinate consular or embassy legalisation, with translation support, for documents headed to countries outside the Apostille Convention.

2. Tan, Lee & Choo Advocates & Solicitors
Tan, Lee & Choo Advocates & Solicitors is a Chinatown law firm at People's Park Complex that has run since 1973. The firm says it keeps two fully qualified Notaries Public on staff, covering document notarisation and signature witnessing, certified true copies of identification and corporate documents, and authentication of powers of attorney, statutory declarations and affidavits. It describes managing the whole chain itself, from notarisation through to submitting documents for a Singapore Academy of Law Apostille, and separately arranges legalisation for documents headed to countries outside the Apostille Convention, with referrals available for document translation. Office hours run weekday mornings to late afternoon, and the firm says it also takes enquiries by WhatsApp and email outside that window.
3. Hoh Law Corporation
Hoh Law Corporation is a multi-branch Singapore law firm that runs its notary public service out of its Adelphi and Jurong offices, with limited availability at Paya Lebar. Its notaries witness and attest documents for use outside Singapore, administer oaths and affirmations for affidavits and statutory declarations, confirm identity against a client's own documents, and certify papers as originals or true copies, before arranging Singapore Academy of Law authentication and an Apostille where needed. The firm advertises same-day collection at Adelphi for documents submitted before 3pm, and next-day turnaround at Jurong for documents received before 11am, both inclusive of SAL authentication. Commissioner for Oaths services are offered more widely, at its Adelphi, Ang Mo Kio, Jurong and Paya Lebar branches.

4. Tan Peng Chin LLC
Tan Peng Chin LLC is a Raffles Place law firm at Singapore Land Tower, with Lim Sim Hui and Jan Goh named as the firm's notaries public. It describes its notarial work as a one-stop service covering certification of passports, identity cards, birth and marriage certificates and corporate documents, administration of oaths for statutory declarations, affidavits and powers of attorney, and the issuing of notarial certificates. From there the firm arranges authentication at the Singapore Academy of Law, including Apostille issuance, and coordinates legalisation with embassies and consulates for documents headed to countries outside the Apostille Convention. Its notary pages don't specify mobile or after-hours appointments, so anyone needing a visit outside standard office hours should ask directly.

5. Alpha Law LLC
Alpha Law LLC is a Toa Payoh law firm whose notaries are appointed under the Singapore Academy of Law framework to notarise documents for use overseas. Its stated scope covers certifying true copies of documents such as marriage and birth certificates, witnessing and attesting signatures and document execution, and administering oaths and affirmations for affidavits and statutory declarations, before coordinating authentication and legalisation through SAL. The firm lists the kinds of documents it commonly notarises as sale and purchase agreements, powers of attorney, deeds and other contracts, incorporation documents, property transfers, intellectual property assignments and wills intended for use abroad. Alpha Law quotes a typical notarisation appointment at 30 to 45 minutes, with authentication and legalisation typically taking a further business day.
6. Menon & Co
Menon & Co, which markets its notarial work under the Notary Singapore name, is a boutique legal practice on Upper Weld Road near Jalan Besar, run by Sumitri Menon as Notary Public, Commissioner for Oaths and advocate & solicitor. The practice describes offering a full range of notary services for clients whose documents will be used overseas, including witnessing and attesting signatures, certifying documents as originals or true copies, and obtaining an Apostille through the Singapore Academy of Law for Hague Convention countries. For other destinations, it says it draws on experience with numerous consular authorities to take documents through SAL authentication and embassy legalisation. The practice also drafts related documents such as wills, powers of attorney and authorisation letters.

7. Loh Eben Ong LLP
Loh Eben Ong LLP is a law firm near Bugis, on Middle Road, that has practised since 1994, with lawyer Eben Ong appointed as its Notary Public since 2010. The firm's notarial work covers certified true copies of both physical and digital documents, witnessing and attestation that requires the client's in-person attendance, and notarisation of ACRA corporate filings, before arranging an Apostille or legalisation in physical or electronic form depending on the destination country. It markets itself around serving clients whose documents need to work overseas, and notes that fees for prescribed acts are fixed by law. Book ahead and bring original documents and photo identification, since certification depends on the notary seeing them in person.
8. JCP Law LLC
JCP Law LLC is a law firm on Battery Road in the Raffles Place area, incorporated in 2021, with an in-house Notary Public handling its notarial work. Its process starts with confirming identity against a government-issued photo ID, witnessing the relevant signatures, and certifying documents as true copies, before Singapore Academy of Law authentication, which the firm says lets recipients verify authenticity through SAL's own portal. For clients who can't get to the office, JCP Law says it offers doorstep collection of original documents, video-witnessed signings followed by document collection, and courier delivery of the notarised set back to the client, all within Singapore. The firm positions this as a more convenient route through the same notarisation and Apostille process.

10. IRB Law LLP
IRB Law LLP, the Singapore law firm founded by managing partner Mohamed Baiross, runs its notarial work under the Notary and Commissioning Singapore name from an Albert Street office near Bugis, alongside its Mountbatten headquarters and other branches. Its notaries witness the execution of documents and certify true copies, administer oaths for affidavits and statutory declarations, and handle legalisation by submitting documents to the Singapore Academy of Law, the Ministry of Foreign Affairs and foreign embassies as required. IRB Law also markets a doorstep option, picking up original documents from the client and couriering the notarised set back, so clients needn't visit in person. That mobile option is worth confirming directly, since coverage isn't detailed on the page.
How to choose
- Confirm whether you actually need a Notary Public or a Commissioner for Oaths. A notary authenticates documents for use overseas, while a Commissioner for Oaths witnesses affidavits and declarations used within Singapore only. Tell the firm what the document is for and which country will receive it before you book, so you don't turn up for the wrong service.
- Ask whether the destination country is party to the Hague Apostille Convention. Documents for member countries generally need notarisation plus a Singapore Academy of Law Apostille, while non-member countries usually need an added round of embassy or consulate legalisation, which involves extra offices and more time.
- Bring original documents and valid photo identification, and check beforehand exactly what the notary needs to see. A notary must personally witness a signing or sight an original before certifying a copy, so incomplete paperwork on the day is the most common reason an appointment gets pushed back.
- Ask about realistic turnaround before fixing a date, especially if a visa, court deadline or overseas deal is time-sensitive. Notarisation itself is often quick, but Apostille or embassy legalisation adds days once the document leaves the notary's hands, and timelines vary by firm and by destination country.
- Notarial fees for prescribed acts are fixed by law rather than set individually by each firm, so there's little to gain from shopping on price alone — focus instead on a clear written scope of what's being certified. If you need mobile, after-hours or multi-language support, confirm it's genuinely offered before relying on it.
