Date First Reported: February 2017

Primary Name Associated: Ken Yao

Description of Potential Fraud:


Firms in Ontario and the US have notified us that they received an email from the purported Ken Yao of Asunaro Aoki Construction looking to retain them with regards to making a large commercial purchase.

This appears to be a bad cheque scam (with a real company likely being impersonated) that presents as legal matter requiring the assistance of a lawyer. In this scam lawyers will be duped into wiring real funds from their trust accounts after depositing a fake cheque received as payment from the purchaser (who is part of the fraud).

See our Confirmed Fraud Page for more of an explanation of how these frauds work and to see other names associated with it. Our Fraud Fact Sheet lists the red flags of a bogus legal matter that is really a fraud.

Here is the initial contact email sent to the lawyer:

Replying to the email brought this response:

This is a follow-up email in regards to my request to you in my previous email; my company is in the process of selling one of its Dredgers. Please find below the name of the proposed buyer for your conflict check. Because of the time difference, I will not be able to establish a call at the moment but I will as soon as we get along. You can add your consultation fee to your retainer.

I want to know your hourly rate for preparing and reviewing a purchase agreement, I have attached some necessary details of the Dredger for your review please advise me on your rate, initial retainer fee and forward me your retainer agreement.


St Lawrence Marine & Dredging
87 Fitzsimmons Rd

The buyer expects a high level of confidentiality in this project because they are currently undergoing a merger process and will like to manage all information relating to all their current on-going transactions.

I await your prompt response.

Ontario Lawyers - Call LAWPRO

If you are an Ontario lawyer acting on a matter that you suspect might be a fraud, call LAWPRO at 1-800-410-1013 (416-598-5899). One of our Fraud Team members will talk you through the common fraud scenarios we are seeing and help you spot red flags that may indicate you are being duped. This will help you ask appropriate questions of your client to determine if the matter is legitimate or not. If the matter you are acting on turns out to be a fraud, we will work with you to prevent the fraud and minimize potential claims costs.

What can you do to help put a stop to the fraud attempt?

You can simply stop replying to the fraudster’s emails or inform them that you suspect fraud and will not act on the matter. You can report the fraudsters’ email addresses to the email hosting company. If you have a fraudulent cheque you can destroy it or send it to the fraud department of the financial institution it is drawn upon. In Canada, you can report the fraud to the Canadian Anti-Fraud Centre.

We are often asked if it is worthwhile to report the fraud attempt to the police in the hopes of helping catch the fraudsters. You can certainly report the fraud to your local or federal law enforcement agencies, but unfortunately it is often difficult, expensive and time consuming for them to attempt to shut down these online fraud perpetrators (though there are some successes).

What if the fraud has been successful?

If you have been successfully duped, please immediately notify LAWPRO as there may be a claim against you. See the LAWPRO website for instructions on how to report a claim.
