Dear cliff12

Contact the Portuguese Embassy or their nearest Consulate, and discuss this with them.

If...

Your parents were not legally married.
Your father failed to report birth of Portuguese citizen overseas to the consulate when you were born..

If these two conditions apply to you, and you are now over 18 years old... forget it.
