LaRue,
I doubt that your son can register the vehicle in Massachusetts without the title being in his name..... Perhaps you can put it in his name and keep a lien on the title?
Unless the vehicle is title in Rue's name, They might ticket the vehicle, but the ticket would be in your name, and you don't live in Massachusetts, so now what do they do?
They should not be able to tow it, as long as it is legally parked...but that may be the fly in the oinment. If Rue gets a ticket or gets the vehicle towed, he might not be able to get the vehicle out of impound unless he is the legal owner? Kind of a Catch-22.
Of course, if nobody is insisting that Rue register the vehicle in MA, then I would not be in any hurry. However, if he has changed his drivers license to an MA license, then that may imply that you are a resident of MA and must register your vehicle in MA.
I had a similar problem when I was stationed in Washington DC and bought my new 1965 GTO. I registered it in VA because they did not have a sales tax at the time. At the time I was living in Washington, DC and had an Ohio Drivers License. About 6 months later I got stopped in Alexandria, VA for going the wrong way down a one-way street (long story). The cop ticketed me for not having a valid drivers license because he said that within 72 hours after registering a vehicle in VA, I was required to have a VA drivers license?? When I went to court, the judge threw out the invalid drivers license charge and admonished the police officer stating that as a member of the military I could register my vehicle in any state I choose to regardless of my residency or what state my Drivers license was from.
He did fine me $25 for going the wrong way on a one-way street, but suspended $10 so I only had to pay $15 plus about $3 court costs...:grin:
