How do I check if my step-family is being honest about family trust and power of attorney for my mom

Good morning. I practice Wrongful Death and all other Personal Injuries, Work Injuries (Workers' Compensation and Social Security Disabilities. I'm an attorney in licensed in California and do not know Arizona Probate laws. All I can tell you is that the attorney who drafted these documents probably has them at his office. Thank you for contacting my Firm. We  wish you good luck in all your future endeavors.
