About Law Office of Vinh T. Tran

The Law Office of Vinh T. Tran, Esq. is a solo Toronto practice built around a narrow specialty: legal opinion letters confirming the validity of a foreign divorce for clients who plan to remarry in Ontario. Tran is a Barrister and Solicitor in good standing with the Law Society of Ontario, a registered notary public, and a Commissioner of Oaths for the courts and Province of Ontario, and is also registered with Global Affairs Canada and Ontario's Official Documents Services Branch. Beyond the divorce opinion letters, the practice handles notarization, the commissioning of affidavits and statutory declarations, and document certification, and takes on business, contract, civil litigation, estate planning, and immigration matters.

Tran holds a specialized honours degree in clinical psychology from York University and a law degree from the University of Windsor, and also founded ONeLAW.ca (branded 1LAW.ca), a separate mobile notary and commissioner service. The practice works by appointment only and serves clients across the Greater Toronto Area, meeting many of them through house calls rather than at a storefront office, including visits to hospitals and nursing homes. Tran is fluent in English and Vietnamese and conversational in Cantonese.

The neighbourhood

The Law Office of Vinh T. Tran, Esq. keeps a suite at 639 Dupont Street, but that address isn't where most clients actually meet with the lawyer. The practice runs by appointment only and describes itself as a GTA house call service, with Tran travelling to the client rather than the other way around. The site points to stops across the city and region, including Yorkdale Shopping Centre and the Eaton Centre, along with visits to hospitals and nursing homes for clients who can't easily travel to an office.

Frequently asked questions

What is a foreign divorce opinion letter and why would I need one?
It's a legal opinion letter that addresses the validity and recognition of a foreign divorce court order or decree in Ontario. Clients who were divorced outside Canada and want to remarry in Ontario typically need one to satisfy provincial marriage licence requirements.
How much does a foreign divorce opinion letter cost and how fast can I get one?
The fee depends on turnaround time: $200 tax included for 3 to 5 business days, $300 for 1 to 2 business days, or $400 for same day to 24 hour service, subject to availability. The fee covers intake, certified copies of ID and the divorce decree, a Statement of Sole Responsibility, and the opinion letter itself in duplicate, properly commissioned and notarized.
Does the Law Office of Vinh T. Tran only handle foreign divorce letters?
No. The practice also provides notarization and the commissioning of oaths, affidavits, and statutory declarations, and Tran advises on business and entertainment law, contracts, civil litigation, estate planning (wills, powers of attorney, probate administration), and immigration matters.
Can Tran meet me somewhere other than the Dupont Street office?

Tran is fluent in English and Vietnamese and conversational in Cantonese.
