When do you put its' in a sentence?

Answer 1

You should never put its' in a sentence. The correct possessive form of "it" is "its", without an apostrophe. While "its'" is never used, "it's" is a contraction of "it is" or "it has".

Answer 2

The word "its" does not require an apostrophe when used as a possessive pronoun. Only use "its' " when it is a contraction for "it is" or "it has," and never as a possessive form.
