What actions to I need to perform, do I need an attorney, where do I go, and how much will it cost to revoke a beneficiary deed in Arizona?

Hi there, it sounds like you need to contact a real estate attorney. They specialize in real estate law, and can guide you in the right direction with respect to deeds, and beneficiaries.

You can check out Consumer Attorney Services (http://www.consumerattorneyservices.com/), and ask them your question on their website. They have a 24/hr chat support, and offer free consultations.
