Ever wonder why ‘judgement’ and ‘judgment’ are both correct? This is the answer:
In British English, ‘judgement’ is the general correct spelling and applicable in everyday English. However, ‘judgment’ is preferred in legal context.
In American English, ‘judgment’ is the correct spelling. This implies that the spelling used only in legal context in British English is what’s generally used in American English.
Both spellings are said to have been in existence for a long time, but Noah Webster helped popularize ‘judgment’ when he compiled the American English dictionary, just like he did with other American words that are shorter than their British counterparts (e.g. labor, maneuver).
