Sometimes, we need to end sentences with "is" or "are" to avoid repetition, but is it correct in formal language?

For example:

Only error-free documents are taken seriously. I will make sure yours is.

    The question is, “what will be ensured: that it will be taken seriously or that it is error-free” – Jim May 19 '17 at 19:41
  • He/she, will make sure his/her document is error free, and therefore, taken seriously. Seems to be the comment of an editor, professional or otherwise. – Ronny Bryson May 19 '17 at 20:07
  • Where do you think the problem..., I mean, if this is true, who told you it... ahem... Why do you think this is (the case)? – Canis Lupus May 19 '17 at 22:20

    Is it correct? Yes, it is. – mahmud koya May 20 '17 at 0:47
  • Deleting (ie missing out) the participle (etc) after an auxiliary may be considered to leave a fragment. But fragments are used extremely commonly in real life: 'Where's the remote? ... 'On the table.' ... 'Is the TV magazine there too?' ... 'Yes.' and/or 'It is.' – Edwin Ashworth Aug 19 '17 at 15:45

It is perfectly valid syntax. However, for various reasons the usage is discouraged (but not avoided entirely) in formal speech/writing.
