Guaranteed. Simple. Trusted.
Be sure to write clearly and sign/print your name exactly as spelled on the front of your title. Avoid white-out, scribbles, and strike-throughs.
Only one owner must sign if title states "OR" or "AND/OR" between owner names printed on the front of the title.
Both owners must sign if title states "AND" between owner names or if nothing is listed between owner names.
If your Delaware title shows a lien or a bank name printed on the front, then your title will need to be signed off by the lien holder or have a separate lien release letter.
