Welcome to SpanishDict, Betty. - rac1, Sep 2, 2017

What is the context? - rac1, Sep 2, 2017

I wasn't thinking of any context in particular, but for example someone trips because of you and you want to say "sorry, that's my fault" - Zpanik, Sep 3, 2017

Answer 1

The natural way for me is: "es mi culpa".

Hi betty, welcome to the forum.

Juan Carlos said this, I wonder if he is a native speaker.

Juan, por qué no das esta información en el perfil, sería más fácil ver de dónde eres.

Anyway, betty, I would use it this way:

¿Has comprado sal?

Vaya, se me ha olvidado. Pero creo que no me lo dijiste ...ahora que lo pienso.

¡hala! Ahora es culpa mía.

Here the stress would be on MY fault.

Answer 2

Both are heard and used. I would only say that maybe ¡Culpa mía! could be a little more used alone in an exclamation and both of them also in any other sentence. There is no big deal in making a difference.

Answer 3

Both are used the same and are correct.

The natural way for me is: "es mi culpa".

Answer 4

This might be answer to your question. My fault = Mi culpa / culpa mia
