If the child lived with you all year and you were the custodial parent then mail in your return with the child listed. Attach a statement about your dependent being claimed by another and send a copy of all the following
Birth certificates or other official documents of birth, marriage certificates, letter from an authorized adoption agency, letter from the authorized placement agency, or applicable court document that verify your relationship to the child (send these documents only for a qualifying child who is not your natural or adopted child).
To show both you and your child lived together at the same address or addresses for more than half of 2015, send either:
• School, medical, daycare, or social service records.
• A letter on the official letterhead from a school, medical provider, social service agency, or place of worship that shows names, common address and dates. (If you send a letter from a relative who provides your daycare, you MUST send at least one additional letter that provides proof.)
If you were not the custodial parent let me know.
After you view my response, please post below if you need more information BUT if you need no further clarification a positive rating is appreciated.
