Of the following sentences which denotes the meaning - "I have done wrong and am to blame":

Is there any difference in meaning between the phrases "At fault" and "In fault"?

Kindly advise me.

Nothing. Where did you encounter it?

I have found it in a grammar book where it has mentioned the usage of the phrases as hereunder:

1) I am at fault : I am puzzled.

2) I am in fault : I have done wrong and am to blame.

But I was somewhat perplexed with the usage given in the examples. On account of this I asked you to advise me whether there is any difference in meaning between the phrases.

I'm pretty sure it's meaningless in all varieties of English.

@Barman If you say you are at fault for something it means you accept blame for it.

I would say that "in fault" is so archaic that most native speakers wouldn't even know it was ever used. We don't use it in modern English.
