So... I have no idea the actual answer, but if it were me, and I have seen how similar things worked in CA where I live, here is what I would do:
Go to the web site for the court, likely used. If you don't know which court, start with the city and search all of the courts there. Each search is fast, so it won't take that long.
The search in my jurisdiction is by date, and one can include the names of the parties involved. I have looked up civil matters by name, going back several years. Going back decades might be less fruitful.
The courts in my jurisdiction allow you to download the various filings for a small charge. If you need a certified copy, you would likely have to call the court. But at least by that point, you would have a case number, which would make that possible...
