38 CFR 3.109 - Time limit.
(a)Notice of time limit for filing evidence.
(1) If a claimant's application is incomplete, the claimant will be notified of the evidence necessary to complete the application. If the evidence is not received within 1 year from the date of such notification, pension, compensation, or dependency and indemnity compensation may not be paid by reason of that application ( 38 U.S.C. 5103(a)). Information concerning the whereabouts of a person who has filed claim is not considered evidence.
(2) The provisions of this paragraph are applicable to original initial applications, to applications for increased benefits by reason of increased disability, age, or the existence of a dependent, and to applications for reopening or resumption of payments. If substantiating evidence is required with respect to the veracity of a witness or the authenticity of documentary evidence timely filed, there will be allowed for the submission of such evidence 1 year from the date of the request therefor. However, any evidence to enlarge the proofs and evidence originally submitted is not so included.
(b)Extension of time limit. Time limits within which claimants or beneficiaries are required to act to perfect a claim or challenge an adverse VA decision may be extended for good cause shown. Where an extension is requested after expiration of a time limit, the action required of the claimant or beneficiary must be taken concurrent with or prior to the filing of a request for extension of the time limit, and good cause must be shown as to why the required action could not have been taken during the original time period and could not have been taken sooner than it was. Denials of time limit extensions are separately appealable issues.
