38 CFR §21.7320

1. (a)Notice of reduction required when a veteran loses entitlement to additional educational assistance for a dependent. Except as provided in paragraph (b) of this section, VA will not reduce an award of educational assistance following the veteran's loss of a dependent unless:
   1. (1)VA has notified the veteran of the adverse action; and
   2. (2)VA has provided the veteran with a period of 60 days in which to submit evidence for the purpose of showing that the educational assistance should not be reduced.
2. (b)No advance notice required in certain situations. When the reduction is based solely on written, factual, unambiguous information as to dependency or marital status provided by the veteran or his or her fiduciary with knowledge or notice that the information would be used to determine the monthly rate of educational assistance allowance:
   1. (1)VA will not send either an advance or a prereduction notice as stated in paragraph (a) of this section; but
   2. (2)VA will send notice of the adverse action contemporaneous with the reduction in educational assistance.
