# 3837.23 How do I notify BLM that I have acquired a delinquent co-claimant's interests in a mining claim or site?

If you acquire a delinquent co-claimant's interests in a mining claim or site, you must submit—

(a) Evidence that you properly notified the delinquent co-claimant;

(b) An originally signed and dated statement by all the compliant co-claimants that the delinquent co-claimant failed to contribute the proper proportion of assessment work, expenditures, or maintenance fees within the period fixed by the statute; and

(c) A non-refundable service charge for a transfer of interest, as found in the table of fees in § 3830.21 of this chapter.
