I don't know how to access your specific county's online system, however this is what I suggest you do to get started:1) Unless involving a guardianship for a minor, probate cases of Decedent's estates are public information. 2) Ask to see the Registry of Actions or similarly title list of new cases3) Start with a single case, typically the most recent filing.4) Request to pull the actual file to review5) Review the folder and note the documents and the order in which they are inserted6) Don't even think of separating or removing documents. 7) Determine what data you need, including Decedent's name, case #, PR name and contact info, etc.8) Most researchers capture the data then scrub later.9) If this is too much work, either pay someone else, find a commercial list provider or work another niche.
