Do I need to be present to sign the papers when buying a car?

Not always. Many dealers now allow remote or electronic signing for some or all documents, and some states allow notarized or e-signed forms for title and registration. Requirements vary by dealer, lender and state, and some documents may still need a wet signature or in-person ID check. Ask the seller what can be signed remotely, read every document fully before signing, and make sure you receive complete copies.
