My birth and my wife's birth is registered in lisbon, but we have not registered the marriage in Portugal. Is it possible to register the birth of my son in portugal without registering my marriage.
What is the cost of the marriage registration. And the other documents reqd
Thanks

If you and your wife hold Portuguese passports, you don't need to be legally married to register your child's birth.
You can report birth of your child at the nearest Portuguese embassy.
