5 Best Notary Public in Sydney (2026)

Armstrong Legal is a large, multi-practice Sydney firm built primarily around criminal, traffic and family law, with lawyers available around the clock for urgent criminal matters. It operates across New South Wales with coverage extending well beyond the CBD into dozens of local courts. It's the highest-volume name on this list by review count, and its reputation centers on individual solicitors like Kent Park, Emily Wood and Sophie Ogborne rather than a dedicated notary desk.

City Notaries, run by principal solicitor and public notary Shahen Davityan, is the only firm on this list built entirely around notarial work: certifying copies, verifying company and ASIC records, witnessing signatures, taking affidavits and issuing Apostille certificates. It operates out of Kent Street on weekday business hours only, and Davityan's fluency in Armenian and Persian is noted directly on the firm's own site.

Agape Henry Crux is primarily an immigration law practice, handling visa refusals, sponsorships, partner visas and complex character-related cases, and its Google profile also carries a notary public listing. Its Pitt Street office runs extended weekday hours until 7pm, longer than most firms here.

Brightstone Legal is a Martin Place firm that explicitly lists notary public as one of its practice areas alongside commercial law, criminal defence, immigration, family law and tax, with three solicitors assigned to that notarial work according to its own site. It's a newer name with a smaller review base than some rivals here, but its rating is the second-highest on this list.

Sterling Legal is a Pitt Street firm whose public reviews center on family law litigation and property conveyancing rather than notarial services, with solicitors Tom, Lamia, Ehab and Daniel named repeatedly across custody and settlement cases. One client's own account describes a three-year litigation closed with full custody and an 80 percent property settlement.
