In the course of representing a client, a lawyer shall not knowingly make a false statement of material fact or law to a third person.

Misrepresentation.
A lawyer is required to be truthful when dealing with others on a client's behalf, but generally has no affirmative duty to inform an opposing party of relevant facts. A misrepresentation can occur if the lawyer incorporates or affirms a statement of another person that the lawyer knows is false.
Statements of Fact.
This rule refers to statements of fact. Whether a particular statement should be regarded as one of fact can depend on the circumstances. Under generally accepted conventions in negotiation, certain types of statements ordinarily are not taken as statements of material fact. Estimates of price or value placed on the subject of a transaction and a party's intentions as to an acceptable settlement of a claim are in this category, and so is the existence of an undisclosed principal except where nondisclosure of the principal would constitute fraud.
Fraud by Client.
Making a false statement may include the failure to make a statement in circumstances in which silence is equivalent to making such a statement. Thus, where the lawyer has made a statement that the lawyer believed to be true when made but later discovers that the statement was not true, in some circumstances failure to correct the statement may be equivalent to making a statement that is false. When the falsity of the original statement by the lawyer resulted from reliance upon what was told to the lawyer by the client and if the original statement if left uncorrected may further a criminal or fraudulent act by the client, the provisions of Rule 1.6(c)(3) give the lawyer discretion to make the disclosure necessary to rectify the consequences.
