12- 172 C.M.R. ch. 11, § 7
When rendering a determination under subsection 3 and subsection 7 of 1192 of the Employment Security Law, the deputy may impose a denial for an indefinite period of time, beginning with the effective date of the first week claimed in which the issue exists, and continuing until the claimant proves to the satisfaction of the deputy that the conditions causing the issue no longer exist. The claimant must provide whatever documentation is deemed necessary on forms prescribed by the deputy to verify that the condition no longer exists. The determination will contain language informing the claimant of the responsibility to provide such documentation and advise the claimant to contact the bureau when the condition which caused the denial of benefits no longer exists.
