Title 28 - Judicial Administration
(a) A claimant for any benefit or fee under the Act and this part shall submit such evidence of eligibility or other material facts as is specified by this part. The Bureau may require at any time additional evidence to be submitted with regard to entitlement, the right to receive payment, the amount to be paid, or any other material issue. (b) Whenever a claimant for any benefit or fee under the Act and this part has submitted no evidence or insufficient evidence of any material issue or fact, the Bureau shall inform the claimant what evidence is necessary for a determination as to such issue or fact and shall request the claimant to submit such evidence within a reasonably specified time. The claimant's failure to submit evidence on a material issue or fact as requested by the Bureau shall be a basis for determining that the claimant fails to satisfy the conditions required to award a benefit or fee or any part thereof. (c) In cases where a copy of a record, document, or other evidence, or an excerpt of information therefrom, is acceptable as evidence in lieu of the original, such copy or excerpt shall, except as may otherwise clearly be indicated thereon, be certified as a true and exact copy or excerpt by the official custodian of such record, or other public official authorized to certify the copy.
