30 CFR 581.41 - Requirements for filing for transfers.
(1) All instruments of transfer of a lease or of an interest therein including subleases and assignments of record interest shall be filed in triplicate for approval within 90 days from the date of final execution. They shall include a statement over the transferee's own signature with respect to citizenship and qualifications similar to that required of a lessee and shall contain all of the terms and conditions agreed upon by the parties thereto.
(2) An application for approval of any instrument required to be filed will not be accepted unless a nonrefundable fee of $50 is paid electronically through Pay.gov at: https://www.pay.gov/paygov/ and a copy of the Pay.gov confirmation receipt page is included with your application. For any document you are not required to file by these regulations but which you submit for record purposes, you must also pay electronically through Pay.gov a nonrefundable fee of $50 per lease affected, and you must include a copy of the Pay.gov confirmation receipt page with your document. Such documents may be rejected at the discretion of the authorized officer.
(b) An attorney in fact signing on behalf of the holder of a lease or sublease, shall furnish evidence of authority to execute the assignment or application for approval and the statement required by § 581.20 of this part.
(c) Where an assignment creates separate leases, a bond shall be furnished for each of the resulting leases in the amount prescribed in § 582.40 of this title. Where an assignment does not create separate leases, the assignee, if the assignment so provides and the surety consents, may become a joint principal on the bond with the assignor.
(d) An heir or devisee of a deceased holder of a lease or any interest therein shall be recognized as the lawful successor to such lease or interest if evidence of status as an heir or devisee is furnished in the form of:
(1) A certified copy of an appropriate order or decree of the court having jurisdiction over the distribution of the estate, or
(2) If no court action is necessary, the statement of two disinterested persons having knowledge of the fact or a certified copy of the will.
(f) In the event an heir or devisee is unable to qualify to hold the lease or interest, the heir or devisee shall be recognized as the lawful successor of the deceased and be entitled to hold the lease for a period not to exceed 2 years from the date of death of the predecessor in interest.
