You must sign and date in two places on the motion.
First, you must sign and date your motion on the second page. If you chose to sign electronically, this is already done. The electronic signature will look like this: /s/ Your Name.
Second, you must sign the Affidavit (on page 3, the page that starts “I declare under penalties of perjury”). You have to do that in front of a notary public or a court clerk. The court clerk will verify your signature for free. If you choose to use a notary there may be a fee. You may be able to get your documents notarized at a bank. Some copy and print shops also offer notary services for a fee. Contact the bank or other location to make sure that a notary will be available at the time you plan on going.
You will need to show the clerk or notary photo identification, such as your driver’s license or state identification card, before you sign the Affidavit and Claim.
If you're signing the Affidavit in front of a court clerk, make four copies of the whole motion (including your attached proof that you used to own the property (like a copy of the deed)) before you sign your documents. Bring all of the copies with you to the court clerk.
If you're signing the Affidavit in front of a notary, make four copies after you sign your documents.
If you are filing a Fee Waiver Request (see Step 3), sign and date it if it does not already have your electronic signature on it. Make four copies of that as well.
No matter how you sign, if you are filing either by e-mail or using MiFILE, you will not need to make copies for the court. You will only need to make a copy for the other party. If you are not sure yet how you will file, you can make copies and discard them later if you do not need them.
