In American English, judgement is generally considered a misspelling of judgment for all uses of the word, notwithstanding individual preferences. In British popular usage, judgment was traditionally the preferred form, but judgement has gained ground over the last couple of centuries and is now nearly as common as judgment. Pay no attention to the myth, widely repeated on the web, that judgement is the original spelling and that judgment is a 19th-century American invention. This is simply untrue.

Hi Sinem, They're actually the same. "Judgement" is simply an alternative spelling of "judgment." While "judgment" is technically the correct spelling, the word has been spelled "judgement" so often that it's now acceptable under non-professional circumstances to spell it that way. I hope I've helped answer your question. Please let me know if I haven't.
