Digital Signature Acceptance Program (DSAP)
(Government Code §16.5, Vehicle Code §§1801, 1801.1, and 23300)
DMV has established a DSAP for the acceptance of digital signatures. This allows First Line Service Providers (FLSPs) to submit approved documents electronically with digital signatures and authentication.
Note Although electronic and digital signatures are both used to sign documents, they are not legally the same and each has unique features.
An electronic signature:
- Refers to any signature that is applied electronically to a document as opposed to physically (also known as a “wet” signature).
- May be used to confirm information and content within a document.
- May include a digitized image of a handwritten signature or name typed into a signature block on a form or document. Examples:
Jonathan Jones
Jonathan Jones
A digital signature:
- Uses cryptography to bind a digital certification and date signed into a unique signature, with security features making it difficult to replicate or alter. This is accomplished using a trusted third party who is responsible for verifying and authenticating the signer’s identity according to standards set by the California Secretary of State and federal regulations, including Government Code §16.5.
- Has a format that may be in cursive or printed text. Examples:
e-signed 08/28/2022 8:40 AM MI 123-4567 or
Jonathan Jones e-signed 08/28/2022 8:40 AM MI 123-4567
A majority of DMV forms may be submitted with an electronic signature, with the following exceptions:
- Any original printed form that releases or transfers interest in a vehicle or vessel
(for example, reports of sale must have physical “wet” signatures) - The following original titling documents, which must be submitted to DMV to finalize the transactions (transactions may be initiated using a copy of the form):
- California Certificate of Title (REG 17.30)
- Certificate of Ownership Vessel (REG 17.31)
- California Salvage Certificate (REG 489)
- Nonrepairable Vehicle Certificate (REG 490)
- Forms that are authorized to be reproduced electronically, including forms that transfer ownership such as the Vehicle/Vessel Transfer Reassignment Form (REG 262), may be signed electronically or digitally in the buyer’s and seller’s sections, but the power of attorney section must be digitally signed. Signature authority for odometer statements may be conveyed through power of attorney.
- Electronic forms with odometer disclosure statements must have digital signatures in accordance with federal regulation.
- Forms that require a Notary Public must be notarized in accordance with the following:
- Notarizations may be done electronically, however, the notary’s signature must be a digitized version of their genuine signature. A signature is one that is not keyed or produced from an available computer font but is in the likeness of the signatory’s actual signature such as a digitized impression. The signatures of the signers witnessed by the notary can be electronic or digital. Examples of forms requiring notarized signatures include:
- Application for Replacement or Transfer of Title (REG 227), Section 5.
- Lien Satisfied/Legal Owner/Title Holder Released (REG 166).
- Registered Owner Notarized Certification (REG 5065).
- Notarizations may be done electronically, however, the notary’s signature must be a digitized version of their genuine signature. A signature is one that is not keyed or produced from an available computer font but is in the likeness of the signatory’s actual signature such as a digitized impression. The signatures of the signers witnessed by the notary can be electronic or digital. Examples of forms requiring notarized signatures include:
The forms listed below may be submitted electronically using a digital signature. Physical reproductions of digitally signed forms are acceptable for processing. All forms with digital signatures must also be submitted through an FLSP participating in the DSAP, which documents the required digital signature certification.
- Bill of Sale (REG 135)
- Unobtainable Title Certification for Issuance of Salvage/Nonrepairable Certificate (REG 492)
- Vehicle/Vessel Transfer Reassignment Form (REG 262)
- Additionally, the following Report of Sale forms may be submitted by FLSPs with digital signatures through the Electronic Report of Sale/Temporary License Plate (eROS/TLP) Programs:
- Application for Registration of Multiple New Vehicles (REG 397A). The digital signature is required at the bottom of page 1, beneath the list of vehicles.
- Application for Registration of New Vehicle (REG 397)
- Report of Sale – Used Vehicle (REG 51)
- Vehicle Auction Wholesale Report of Sale (REG 398)
- Wholesale Report of Sale (REG 396)
8.005 Collection of California Sales Tax
- California licensed dealers must collect the sales tax due on vehicles sold by the dealership.
- Completion and submission of the REG 51 on a registration application is an assumption that the tax was collected.
Note Sales tax is due if the buyer takes delivery of the vehicle in California. Contact the California Department of Tax and Fee Administration at 1-800-400-7115 for additional information.
- Refer to the “City and County Fees”, Appendix 1A, for sales tax rates.
8.000 General Information
California licensed dealers must report the retail sale of all used vehicles on the Report of Sale–Used Vehicle (REG 51) form. The REG 51 is not used to report sales to wholesale dealers nor sales of vessels.
The REG 51 is a controlled form and can only be obtained from the DMV Occupational Licensing Section.
Orders for additional forms are only accepted by mail on a Used Report of Sale, REG 51, Order Form (OL 395U) form. This form is available online at www.dmv.ca.gov and must be mailed to the address on the form.

7.100 Kit Vehicles
A kit vehicle is a vehicle that is built for private use, not for resale, and is not constructed by a licensed manufacturer or remanufacturer.
- Kit vehicles are often replicas of well-known and expensive classics but can also be commercial vehicles and trailers.
- A kit vehicle is registered by the kit manufacturer’s VIN (they are exempt from the federal 17-digit VIN requirement) and does not have a model year. The make abbreviation is the kit make followed by the abbreviation KT.
- All kit motor vehicles and kit trailers weighing 6,001 pounds or more unladen, and vehicles having more than one VIN must be referred to the California Highway Patrol (CHP) for a VIN verification or assignment.
- A “CAL” number is assigned by DMV to trailers with an unladen weight of 6,000 pounds or less, unless the original unaltered VIN remains on the frame.
Commercial Vehicles Assembled from Kits (VC §580)
Manufacturers of large commercial vehicles sell kits which can be made into complete vehicles.
- These kits usually consist of a frame, steering gear, cab (complete with wiring and instruments), radiator, hood, front fenders, and in most cases, the front axle and wheels.
- The installation of an engine, transmission, rear axles, wheel, and tires makes the kit a complete vehicle.
- The installed components may have been purchased separately in new or used condition or removed from a vehicle which is no longer serviceable.
- Installation into the kit may have been done at an assembly plant, a truck repair shop, or by an individual.

- Bill(s) of sale or a junk receipt for the major component parts (engine, frame, transmission, and body).
- If a Certificate of Origin is submitted, it may be accepted as a bill of sale only for the parts described. However, a Certificate of Origin may be presented as evidence of ownership for a complete vehicle only if it is an unassembled trailer kit.
- If the vehicle was assembled from parts of a vehicle owned by the applicant, the applicant must have reported the vehicle “junked”.
- A Motor Vehicle Ownership Surety Bond (REG 5057) (PDF) if the vehicle value is $5,000 or more and the required receipts for the major component parts are not submitted.
- A Statement of Construction (REG 5036) (PDF) completed and signed by the owner. The total value on the REG 5036 must agree with the market value shown on the REG 343.
- An electronic Vehicle Safety Systems Inspection (VSSI) certificate. Refer to Chapter 19.090 Vehicle Safety System Inspection Program
- The VSSI certificate exemption, due to distance from an inspection facility, is being discontinued. When a VSSI station that inspects specific vehicles such as motorcycles and large commercial vehicles is not located within a reasonable distance, a Statement of Facts (REG 256) (PDF) form from a repair shop attesting that the brakes and lights are in proper working order is not acceptable.
- A VSSI certificate is not required for trailers weighing under 3,000 lbs. gross vehicle weight.
- Weight certificate for a commercial vehicle weighing less than 10,001 pounds.

7.095 SPCNS Certificate of Sequence (VC §4750.1)
A SPCNS Certificate of Sequence allows an owner of a SPCNS vehicle to choose whether the smog requirements for the vehicle are based on the model year of the engine used in the vehicle or the year the vehicle is being registered.
- Each calendar year, a Certificate of Sequence is issued by DMV to the first 500 owners of specially constructed (SPCNS) vehicles who either:
- Present any type of registration transaction for an SPCNS vehicle
- Request issuance of a Certificate of Sequence only (when the vehicle is not subject to a registration transaction).
- After the 500 are issued each year, SPCNS vehicles will be evaluated for emission requirements by BAR based on the criteria for SPCNS vehicles. Contact a BAR referee for further information.
7.090 Specially Constructed Vehicles (VC §§580 and 4153)
A specially constructed vehicle (SPCNS) is a vehicle built for private use, not for resale, and not constructed by a licensed manufacturer or remanufacturer.
- Specially constructed vehicles may be built from a kit, new or used parts, a combination of new and used parts, or from a vehicle reported as dismantled, as required by VC §§5500 or 11520 which, when reconstructed, does not resemble the original make and model of the vehicle that was dismantled.
- A specially constructed vehicle does not include a vehicle which has been repaired or restored to its original design by replacing parts or modified from its original design, but not completely assembled from parts, which is still recognizable as the original make.
-
Example #1-A Volkswagen modified with a conversion kit to give the appearance of having the grill of a Rolls Royce is not registered as a specially constructed vehicle, because it still resembles and would be recognized as a Volkswagen.
This also applies to a Volkswagen modified with a “Baja Kit” in which the fenders, engine compartment lid, and possibly the front end, are modified, but leave the vehicle still recognizable as a Volkswagen. -
Example #2-A motorcycle, such as a Harley Davidson, modified only with extended forks but still recognizable as a Harley Davidson is not registered as a SPCNS.
However, if a motorcycle is constructed entirely from parts, even if they are Harley Davidson parts, the vehicle cannot be registered as a Harley Davidson since it was not constructed by a manufacturer or remanufacturer; it must be registered as a SPCNS. - Example #3-Vehicles that are modified by a body change only, when the Certificate of Title held by the owner shows the correct make, is not registered as a SPCNS.
-
Example #1-A Volkswagen modified with a conversion kit to give the appearance of having the grill of a Rolls Royce is not registered as a specially constructed vehicle, because it still resembles and would be recognized as a Volkswagen.
- All specially constructed (SPCNS) motor vehicles and SPCNS trailers weighing 6001 pounds or more unladen must be referred to the California Highway Patrol (CHP) for inspection and determination of, or assignment of a VIN.
- SPCNS trailers weighing less than 6001 pounds, except logging dollies, are assigned a VIN by the DMV unless the original unaltered VIN is on the frame.
Smog Certification
The first smog certification for a SPCNS vehicle must be issued by a Bureau of Automotive Repair (BAR) Referee Center.
- Once the vehicle is certified by the referee, a BAR label will be affixed to the vehicle.
- Any licensed Smog Check station may perform subsequent inspections as long as the BAR label remains in place and the vehicle’s emissions equipment remains the same.
