So, I'm currently working on moving to Sao Paulo with my fiance, getting married and getting permanent residency here, and meanwhile we are staying with her family in a small town in MG. Her mother insisted on going to the Cartorio to ask what documents would be needed to register the marriage here because she thinks it will be easier than doing it in SP when our apartment becomes available in about two weeks. Obviously, this wouldn't be ideal because we would have to come back here to actually get married after what we were told would be a 40 day wait for the license. But, beyond that, the person working there told us that we only need my translated birth certificate certified by the Brazilian consulate in the US (I have this), and a registered copy of my passport. This goes against what I've read everywhere on the internet, which says that I need to further get my birth certificate certified by the consulate here, and also get a "Single Certificate."
My future MIL is making a fuss, saying that I'm just trying to overcomplicate the matter and if the Cartorio said that's all we need, that should be everything. Is this right? Do some Cartorios have different standards, or does this country Cartorio just have no experience in this matter, which would only lead to further complicating this situation down the line?
Another, unrelated question I have: what document will I need when applying for the VIPER in regards to criminal record? I've read that it is possible to just sign a document saying that I don't have one and that may be enough, is that true?
Also, does it matter what state I get my documents translated in? If I get my docs translated here in MG, will they be valid in SP?
And one final question: my birth certificate has my father's full name on it, but my mother's maiden name. Will I have to get this updated as well to reflect her married name?
Thanks in advance.
