You can write ICBC head office-North van with a letter including a bill of sale and a explanation of how you got the car, From there It help's to take a couple of picts of the car and send those too,
With a bill of sale ICBC will send you the last known address of the previous owner! Cost about 8 bucks if I remember.
From there they will either send you a disclaimer stating that the owner is dead or an envelope with last known residential address attached.
Now if the owner is dead you must head to a Notary to make sure this car was not willed to a living person
There is a fee involved. If all is clear its in your name!
Now if the envolope has the attachment you must mail it to the last know address with a letter telling that you now own the vechicle and are trying to restore it. You will either get back a unopened letter (meaning the owner now no longer resides there) Or a letter saying GIVE ME MONEY!! Sometimes old owners want money for their signature. It happens alot, or you might get a nice one who just signs and sends it back!
If the owner does not live there you then send back to ICBC a letter saying you have tried to get a hold of the owner to no avail and as long as they have records that it has been insured previously they should give you the papers, Might throw on a saftey inspection(been doing that last little while).
Worst case you get a letter back stating that the vehicale is currently insured........which suck ass!!
