A new complication. When I was writing "I", I was referring to my other half (for ease of sentence structure). Turns out the original ownership certificate may be in his deceased mother's name. Oh dear. I see an affidavit in our future...
Same question as above - and understand all answers - with one addition : I've lost the trailer registration certificate! I asked at the licensing counter at the post office this morning, but they can't find the trailer licence plate on the system. Thoughts?
