Facts only. No legal-advice questions.
Keystone Pinnacle Pro is built to ask factual questions: names, dates, addresses, family relationships, assets, debts, notices, signatures, and filing details. It does not ask users to choose legal strategy, interpret legal rights, decide who should object, or answer questions that require legal advice. If a question turns on legal judgment, the user should confirm requirements with the Surrogate's Court or speak with an attorney.
Keystone Pinnacle Pro helps organize information into form packets you can review, print, sign, and file. We do not choose the correct proceeding for you, represent you in court, or guarantee court acceptance.
