Information on your current credit report includes debt taken out in the last 7 years. You might not even need reports from prior years, but yes, you may be able to get prior credit reports if you have a valid reason and if the CSR you talk to at the credit bureau can find the report.

Frankly, you'll get just as good information here as you would at r/legaladvice. Lawyers follow this forum and chime in on topics. On r/legaladvice, you don't know that the posters are lawyers and based on what I've seen, most aren't.
