By the way, this is for form request. Is the MV-15 type useful if I'm looking for a title record abstract?
That's correct. Is a standard form that can be used for both of the procedures.
And can be even be used to know about other person record information?
In fact, you can. But, along you request using the MV-15 Form, you must certify that you have a permissible use under the Driver's Privacy Protection Act to see the personal information of another driver or perons on DMV records.
