if need be

Should circumstances warrant

If need be means if it becomes necessary or if circumstances require it.

The phrase signals willingness to take action under certain conditions: I'll work through the night if need be.

It suggests contingency—something held in reserve rather than a first resort: We can always hire more staff if need be.
