Vertimas - Portugalų-Vokiečių - Não. Meu pai não!

Shouldn't it be "Nicht mein Vater"?

Nein. Mein Vater nicht.

I'm sorry. I think that I need to sleep!
It's the same "Nicht mein Vater" and "Mein Vater nicht"?

well, it's the same

Nein. Mein Vater nicht!

Nein. Nicht mein Vater!

I was confused, which is the real translation?

The real translation is "Nein. Mein Vater nicht.", this is a discussion about it. Now, you must wait, because a expert need to evaluate it.

Still, there is a little difference between "Mein Vater nicht" and "Nicht mein Vater":

"Mein Vater nicht" could be used in a context like "My mother is really good at sewing but mein Vater nicht", whereas "Nicht mein Vater" could stand in a sentence like "Who is good at sewing? Doch nicht mein Vater!?".

I don't know if there is a difference in emphasis in Portuguese too when you change the word order of that little sentence. Is there?

So, maybe it should be "Nicht mein Vater". I don't know. I'm a little bit confused.

I accepted it the way it was. There is simply not enough context given to find out, what the requester wants to say exactly.

Maybe I'm coming a bit belated now, but, if I can still help, I'd say that the Portuguese original means:

1) "No, not my father!" (he wouldn't be capable of doing such a thing!)

- or -

2) 1) "No, not my father!" (it would be someone else, but not my father!)

That's indeed helpful (and exactly what I tried to find out - but I guess no one but you understood my complicated question )! ..And exactly the opposite version than the one I've just accepted. I will change it. Thanks, goncin!

I don't know if I received the points of the translation, because I don't see any points of german in my profile...

It's because I didn't know, how many "points" to give you, so I accepted the translation without a rating.

I am deeply grateful for the attention you are giving to my sentence "No. My father did not." I want to help and say that in the Romance, the phrase is used by a girl of 6 years to see his father died and she exclaims: No. My father did not! in German.
Actually, goncin gave a hint interesting. The girl uses the phrase, meaning just that: (it would be someone else, but not my father!).

Thanks, friends

Thank you for the additional information, Tenguna. Now we can be sure that the translation is correct the way it is.
