Arizona real estate contracts are typically prepared using:

A is incorrect because custom forms are not typically used in Arizona real estate transactions. While they may occasionally be created for unique situations, they're not the standard practice and lack the legal precedent and industry acceptance of AAR forms.

C is incorrect because ADRE (Arizona Department of Real Estate) forms are primarily for regulatory and licensing purposes, not for real estate transaction contracts. These forms don't provide the comprehensive language needed for purchase agreements and other transaction documents.

D is incorrect because attorney-drafted forms are not required for typical real estate transactions in Arizona. AAR forms are legally sufficient and specifically designed for Arizona real estate transactions, making attorney involvement unnecessary for standard contracts.
