If husband & wife each sell their half interest in principal residence to a third party, do they have to answer the questions in column 3 of the PR Designation Worksheet?

The third column of the PRWS is titled "Questions related to a disposition to your spouse/partner".  Since the sale is to a third party, should both husband & wife leave the questions in column 3 blank, including question 1 which asks: "did your spouse/partner also dispose of this property (if applicable)?".

For the "Lot Number" in column 1 "Address", is this just if the property is on a specific lot number, or are the legal description and parcel ID (e.g. PID, district etc) required?  (Or is a full address - house number, street name, city, postal code and province --- sufficient?)
