Thank you very much Victoria. I've order our tax return transcripts from each year we were married and can include things like leases, car titles, and joint account statements.
I'm going to do a search now to find the answer to this, but if anyone happens to read this question and know, feel free to answer it...
Can you send in photocopies of things like the leases, titles, and statements? Or will they have to be originals?
Off to run my search.
