When we arrived in 2018, I was able to purchase Casa de Conductor separately for a car a friend was lending us to move. At the time, it was $700RD and I purchased it from a Taxi Stand in Sosua, where we are living. I have no idea of the current cost, or where you can buy it in other towns, but it was dirt cheap at the time.- @UncleBuck
My two cents! I did that once with a private rental and it worked out just fine. However I went and got my own insurance for that period of time and I also had him meet me at my lawyer's office and we drew up a brief contract in case I was stopped or he changed his mind and said I had taken the car without permission. I saved some money on the rental and he was happy to have dollars as payment. (it was less then half of what it would have costed me, so I was happy to pay in dollars!). Good luck and make sure its all in writing!
I have both DR property and DR health insurance here. My rental car company tells me it has insurance, but I would love to have a separate policy as mentioned above. Especially to assure that i have casa de conductor. I asked my property insurance broker (universal) about it and says she does not offer it and is unaware of it.
@UncleBuck mentioned it above. I live in Cabarete and any information on attaining it would be appreciated!
