Do you know how you own property that you are joint owners of? You would be either 1. Joint Tenants (JT) or 2. Tenants in Common (TIC) You can vote multiple times if you have a mixture Note, that in rare cases you could be both a JT and a TIC and here we are only considering legal ownership and not beneficial ownership (where the owner may not be on title). Here I am only concerned with jointly owned property - I want to test my theory that most people don't know the answer.
