Well I myself made the same stupid mistake like what your girl have done before. Difference is: my signature wasn't forged. I fell in love with that guy who turned to be a complete jerk. We kept our marriage secret from our families because I just got my first job that time and just graduated from college. So the signatures of the witnesses were forged. After a few years, I filed for annulment here in the Philippines. I asked my lawyer if the forged signatures would also serve as a factor for my annulment like would it be considered as fraud? Aside from the Psychological Incapacity. ground for annulment I had filed. He told me: No. That's only an 'irregularity' on the signed papers perse. Nevertheless, in your case her signature was the one that has been forged. That's considered a prior misrepresentation (fraud). A marriage license will be considered invalid if any of the parties provides fraudulent information. I think she has a big chance to win her case here if she will file for annulment. Heck, it would take her a million years before her petition will be granted. I suggest, she should file a divorce there in Canada. Otherwise, she could wait until the refiled divorce bill here in the Philippines will be approved and settled. Thus, legalizing the divorce in the country.
