It applies to contracts, wills, trusts, financial transactions, and other agreements. The most common type of Oklahoma Undue Influence is called Fraudulent Undue Influence. This occurs when one party uses deception, threats, or other tactics to influence the other party into a contract or agreement, or to prevent them from exercising their free will. Another type of Oklahoma Undue Influence is called Constructive Undue Influence. This occurs when one party has a fiduciary duty to the other, such as a lawyer, accountant, or family member, and uses that relationship to influence the other party into a contract or agreement, or to prevent them from exercising their free will. Oklahoma Undue Influence also includes Mental Undue Influence. This occurs when one party takes advantage of the other's mental or emotional state to influence them into a contract or agreement, or to prevent them from exercising their free will. Finally, Oklahoma Undue Influence may include Duress.
