Just a couple of thought on this!!
It seems to me that the OP has a hell of a lot of interest in this if he is as he implies, just a 3rd party!!! What's the rest of the story
As Mkink said, in CR she has no recourse, the marriage here is void as if it never occurred, and only if they have K*ds can she get anything out of him!!
Secondly, It amazes me how different the laws are in different countries. Here it seems almost all you need is to show up at an attorney's office with the chica and a couple of witness and you can get married. When I married in Colombia, I had to go to the Colombian consulate in Atlanta; present myself for an interview and present copies of birth certificate, previous marriage license(s), copies of all divorces, and a financial statement along with copies of current tax returns. Hell I had to even have pictures of us together dating back at least 6 months and had to show where I had spent time in Colombia (with her) during that 6 months prior to the application. Then if and when they were satisfied that I was truly single, financially able to support her, and that we had an on-going true relationship, they gave me a marriage visa good for (only) 90 days and only in Colombia! At the wedding we had to have 3 witness who would verify that we had an ongoing relationship. Also because Spanish was not my native language, I had to pay an interpreter to be present at the wedding in case I did not understand something that was said ( he never opened his mouth)! Remember this was Colombia, not the USA requiring all this!!!
