43 CFR § 2803.12
What happens to my application or grant if I die?
June 11, 2020
(a) If an applicant or grant holder dies, any inheritable interest in an application or grant will be distributed under state law.
(b) If the distributee of a grant is not qualified to hold a grant under §2803.10 of this subpart, BLM will recognize the distributee as grant holder and allow the distributee to hold its interest in the grant for up to two years. During that period, the distributee must either become qualified or divest itself of the interest.
