I am Mindy Lam, Founder & Principal of Onyx Notary & Apostille, a boutique notary and document coordination practice based in Wheaton, Illinois. I am an Illinois notary commissioned through 8/28/2029, serving clients in-office and by mobile appointment throughout DuPage County and surrounding areas.

My work focuses on reliable apostille facilitation, document runner services, post-signing processing, and general notarizations, including estate planning signings for wills and trusts. I regularly support other notaries, attorneys, estate and trust professionals, universities, and international document services with Illinois Secretary of State runs, county clerk certifications, county recorder submissions, deed recording, certified copies, and time-sensitive deliveries.

I offer mobile, remote, RON-capable, hospital signing, 24-hour, same-day, and expedited services when available. My approach is detail-driven and communication-forward, with careful chain-of-custody practices from intake through completion. Services are performed in English and in accordance with Illinois law.
