Trailer For Sale In Alberta Do I Need A Bill Of Sale For A Utility Trailer?

Do i need a bill of sale for a utility trailer? - trailer for sale in alberta

I think buying a utility trailer that my move across the country, then sellng if I reach my goal. The seller has a title. Do I have to write a turnover from a vendor invoice for me to sell at? Can I have 30 days tags, so we are not through the expensive process of recording to go so I think the sale within 30 days?
