at fault

Deserving the blame

At fault means responsible for something that went wrong—deserving blame for an error, accident, or bad outcome.

The phrase appears frequently in insurance and legal contexts: The other driver was at fault.

It can also describe someone confused or uncertain: I was completely at fault about what to do next, though this sense is now rare.
