As a Delaware notary, I get lots of questions about vehicle title transfers and the role that a notary public in Delaware plays in some instances.
Most importantly, Delaware titles do not require notarization.
You may find the following direct links especially helpful:
The Pennsylvania DMV also has a very informative and easily navigated website with information for new residents including how to title and register your out-of-state vehicle in Pennsylania.
They also have a large repository of forms, publications and maps.
The Maryland Motor Vehicle Administration (MVA) is a resource of the MD Department of Transportation (MDOT) and provides information on titling and registering your vehicle for a new resident as well as selling or buying a vehicle in Maryland.
I hope this list of resources helps you answer any questions you may have about titling a vehicle. Please consider contacting Jamie (302-750-9678) for assistance with any forms or documents that require the services of a Delaware public notary.
