under the title
On the back of the title Part A only
The seller needs to sign on the dotted line and give the title to you. You send it to the address stated on the title to have it changed.
The seller has to sign the title, but it does not have to be done any place in particular. Some states require a Notary to witness it and some don't. On the back of the title, at the top should be the space for the seller and buyer to sign. Usually at the bottom of this box or right under it there is a place for the Notary to sign if it is required. If it is needed , you must sign it with the Notary present.
as seller
Sign off on your part as the seller on the title itself just like you were selling it to anyone else.
the back, under Seller
A seller should never sign except in the presence of a notary. A notary has to witness the seller signing his/her name. Notaries have to take special classes in how those type of documents need to be filled out
Yes, he will sign under Seller and you will sign under Buyer. Some states require a notary public to witness and notarize the signatures, If it is so in Illinois, it would be best to wait to sign in front of the notary public, If notarization is not required, it's ok to sign and then transfer the title. If you are not a car dealer, you sign on the front of the title (in Illinois) in the area under "assignment of title".
Title for what? If it's for a car, and she has legal means to do so (power of attorney), she would sign the back under Seller and note P.A. after her signature.
You will probably have to go to court and get the judge to order it.
No. That is fraud. You need to get the signature of the person whose name is on the title. If your name is on the title you can sell it. If not you can't.
