Can I claim a child that lives in another state but has not lived with me but is related.

[DS30 · Accepted solution]

It depends but if this child does not meet all the requirements of a qualified child (because this child has not lived with you either for more than half of the year or does not fall within special rules for children of parents who are divorced, separated, or living apart (temporary absences for things like schooling, medical treatment, vacations, business, or military service don’t count.), then you may still be able to claim this child as a qualified relative.

What if the parent gave me permission and the relative is my niece?

[DS30]

Yes - you would be able to claim her if she meets the requirements of a qualified relative.
