School enrollment often requires proof that a student lives within the district or attendance boundary. A lease, deed, utility bill, driver's license, or other standard proof may satisfy that requirement, but families do not always live in a situation where those documents are in the parent's name.
When a parent and child live with a relative, friend, homeowner, or leaseholder, a district may use a residency affidavit, shared-residency affidavit, co-residency affidavit, affidavit of residence, or similar form to document where the student actually lives.
The word “affidavit” does not automatically mean the form must be notarized. The district that created the form decides what signatures, supporting records, identification, and notarization it requires.
