My wife (brazilian) and I were married abroad. We have an authenticated copy of our marriage certificate from the brazilian consulate where we got married. The foreign marriage certificate carries my wife's maiden name. Note the marriage was not registered with the brazilian consulate (only authenticated) as they told us it was easier to do it in Brazil (it seemed like this was a hassle for them and they were not too keen to do it for some reason).
We are planning to go to brazil where she will have to register her marriage at the cartorio. The question I have is: what is the procedure for her to adopt my last name? Is this done during the registration process? Does something have to be done prior to that?
If someone has any experience with this I would really appreciate some guidance as I have struggled to find the information.
