Constructive fraud consists: 1. In any breach of duty which, without an actually fraudulent intent, gains an advantage to the person in fault or anyone claiming under that person, by misleading another to the other's prejudice or to the prejudice of anyone claiming under the othe…

Actual fraud is always a question of fact.

Undue influence consists: 1. In the use, by one in whom a confidence is reposed by another or who holds a real or apparent authority over that person, of such confidence or authority for the purpose of obtaining an unfair advantage over that person; 2. In taking an unfair advanta…

Mistake may be either of fact or of law.

Consent is not mutual unless the parties all agree upon the same thing in the same sense. In certain cases defined in chapter 9-07, they are to be deemed so to agree without regard to the fact.

Consent can be communicated with effect only by some act or omission of the party contracting by which the party intends to communicate it, or which necessarily tends to such communication.

If a proposal prescribes any conditions concerning the communication of its acceptance, the proposer is not bound unless they are conformed to. In other cases any reasonable and usual mode may be adopted.

Consent is deemed to be communicated fully between the parties as soon as the party accepting a proposal has put that party's acceptance in the course of transmission to the proposer in conformity to section 9-03-18.

Performance of the conditions of a proposal, or the acceptance of the consideration offered with a proposal, is an acceptance of the proposal.

Except as provided by section 41-02-14, an acceptance must be absolute and unqualified, or must include in itself an acceptance of that character which the proposer can separate from the rest and which will conclude the person accepting. A qualified acceptance is a new proposal.

A proposal may be revoked at any time before its acceptance is communicated to the proposer, but not afterwards, except as provided by section 41-02-12.

A proposal is revoked: 1. By the communication of notice of revocation by the proposer to the other party in the manner prescribed by sections 9-03-17 and 9-03-19 before the latter's acceptance has been communicated to the former; 2. By the lapse of the time prescribed in such pr…

A contract which is voidable solely for want of due consent may be ratified by a subsequent consent.

A voluntary acceptance of the benefit of a transaction is equivalent to a consent to all the obligations arising from it so far as the facts are known or ought to be known to the person accepting.
