When migrant workers across provinces transfer and continue the old-age insurance relationship, if they pay the old-age insurance premium in a lump sum for more than 3 years (inclusive) in accordance with the provisions of the state, the transfer place shall provide the corresponding legally effective supporting documents issued by the people's court, the auditing department, the administrative department that implements labor security supervision or the labor dispute arbitration committee that there is a labor relationship during the one-time payment period.
