Types of Kansas Affidavit of Nonrevocation of Power of Attorney on Date of Execution of Oil and Gas Lease: 1. Individual Affidavit of Nonrevocation: This type of affidavit is executed when an individual who granted the Power of Attorney, typically the lessor, confirms that the authority granted to the attorney-in-fact remains valid and has not been revoked at the time of executing the oil and gas lease. 2. Corporate Affidavit of Nonrevocation: In cases where a corporation or company is the granter of the Power of Attorney, this type of affidavit is used. The designated representative of the corporation, usually an officer or authorized personnel, affirms that the company's Power of Attorney has not been revoked when entering into the oil and gas lease. 3. Joint Affidavit of Nonrevocation: In situations where multiple parties are granting the Power of Attorney jointly, such as co-owners of land, a joint affidavit is executed. All parties involved sign the affidavit, attesting that the Power of Attorney has not been revoked up until the date of executing the oil and gas lease. 4. Substitute Affidavit of Nonrevocation: If the appointed attorney-in-fact under the Power of Attorney is unable or unwilling to execute the affidavit, a substitute affidavit can be prepared. The individual or entity, usually a successor-in-interest or a new attorney-in-fact, provides a statement confirming that the original POA has not been revoked, and they are now acting in the same capacity. Please note that the specific types and terminology used may vary, and it is always recommended consulting with a legal professional to ensure the correct terminology is used for a particular situation.
