It's neither of our faults

[Glizdka]

Although it pains me to ruin my perfect post count, it pains me even more that I don't know if my sentence is correct. Can I say "It's neither of our faults" meaning "It's neither my nor your fault"?

"It's not my fault." + "It's not your fault." → "It's neither of our faults."

Should fault(s) be singular or plural?
Should our(s) be a possessive pronoun or a possessive adjective?
Is the whole idea just wrong from the start?

Your title sentence is used informally.

"It's neither of our faults" is perfectly good.

:up:

It may be grammatical but it sounds wrong to me. I'd prefer It's neither your fault nor mine.
