I don't know if this helps, ex and I basically agreed on household items when we first separated over 3 years ago. The last offer sent through lawyers last year had a number of paragraphs that explained what the offer for division of property was, (house, RRSPs etc), and then there was a paragraph about the household items that said something to the following;
"Except as otherwise indicated, the Plaintiff and the Defendant shall retain any and all other property in their current and respective possession. The parties will agree that all of their household furnishings, effects and other items have been divided to their mutual satisfaction. They agree that the chattels, furnishings and personal property in the possession of the other shall be and remain their sole and exclusive property, and each will waive all right, title and interest in that property."
As far as I know stbx did not have to show his lawyer that we had divided the household items. The conversation I had with my lawyer in response to this offer was a simple "yes" we have divided the household items. My lawyer didn't ask for proof or a list.
