Here's a sample Certification of Non-Advancement of Maternity Benefit 
that you need to submit together with your other maternity benefit claim documents
if the gap between your date of delivery and
date of separation from your employer
is less than 6 months.

SSS specified 6 months as the time frame,
but some SSS officers still require separation documents
even if the gap is already more than 6 months.
