If you are a parent who is registering your child for the first time with the Shelby County (Tennessee) Schools, you will have to provide 2 forms of proof of residence. You can read all about that on the SCS website at http://www.scsk12.org/registration/proof?PID=792
If you are sharing a residence with someone else and your name is not on the lease or the address where you and the child are staying is not the same as the one on your ID, you will need to complete a Shared Residence Affidavit.
Both you AND the person whose name is on the lease (or the homeowner) will need to appear before a notary with the Shared Residence Affidavit and proper ID for each of you and the notary fee in order to have this form notarized.
You can find the Shelby County Schools Shared Residence Affidavit online in a fillable format (meaning, you can put in the information that goes into it before you print it out) here: http://www.pdffiller.com/6267078-NEW20Shared20Residency20Affidavitpdf-Shelby-County-Schools-Shared-Residence-Affidavit-Other-forms-scsk12
Or, there is a blank version (meaning, you fill it in by hand after you get in front of the notary) here: http://www.scsk12.org/registration/files/2015/Shared%20Residence%20Affidavit.pdf
The Shelby County Schools Shared Residence Affidavit is just one of many documents which I have experience notarizing. Please see a partial list here: Can You Notarize My Document?
