What happens to my application, grant, or TUP if I die?
June 11, 2020
(a) If an applicant or grant or TUP holder dies, any inheritable interest in the application, grant, or TUP will be distributed under state law.
(b) If the distributee of a grant or TUP is not qualified to hold a grant or TUP under §2883.10 of this subpart, BLM will recognize the distributee as grant or TUP holder and allow the distributee to hold its interest in the grant or TUP for up to two years. During that period, the distributee must either become qualified or divest itself of the interest.
