It depends on the sentence to say whether it its grammatically correct. If someone were to say, for example, "I have no money." Yes, it would be correct. If someone were to say "No, I don't have no money." It would be incorrect because it is a double negative. A double negative is when in one sentence you would use the word "no", or a conjunction with no, as in "don't" or "won't" more than once without a proper comma in place. To correct the example sentence, one might say "No, i don't have any money." or "No, I haven't any money."
