Origin
Diane L. Drain Phoenix: From Paralegal to Law Professor to Founder
Diane Drain earned her B.S. from Arizona State University in 1983 after 15 years working as a paralegal, legal secretary, and law office administrator — a background that gives her direct, pre-law-school familiarity with how a law office actually runs. She has practiced as a bankruptcy lawyer since the mid-1980s, first at a large firm and later at her own practice, and has also served as a law professor, a role from which she is now retired.
Practice
Consumer and Small-Business Debt Relief, Plus Foreclosure Defense
Drain’s practice centers on Chapter 7 and Chapter 13 consumer and small-business bankruptcy, along with foreclosure defense. Her client base has included commercial mortgage lenders, national banks, and professionals such as lawyers and brokers, though her own materials describe her greatest professional reward as coming from helping individuals navigate financial hardship directly.
Track Record
Awesome Attorneys did not identify an independent, itemized case-results table for this firm, which is typical for a consumer bankruptcy practice given confidentiality and court-record limitations.
Past-Results Disclaimer: Every matter is different, and no past result guarantees a similar outcome in any future matter.
Client Voice
The firm carries roughly 115 reviews across aggregated platforms at a 4.8-out-of-5.0 rating, with reviewers consistently describing Drain as patient, thorough, and effective at explaining a stressful process in plain terms. Multiple reviews specifically credit her staff, including a paralegal named Jay, for responsiveness throughout the case.
Community
Drain has volunteered at pro bono legal-assistance events for veterans and is described by a fellow attorney as an active mentor to young bankruptcy lawyers in Arizona. She received the Maricopa County chapter of the Arizona Women Lawyers Association’s Ruth V. McGregor Award and a Lifetime Achievement Pro Bono Award presented on behalf of the Arizona Bankruptcy Section and the Arizona Bankruptcy Court.
Recognition
Drain holds an AV rating from Martindale-Hubbell, the service’s highest peer-review tier. In September 2025, she received the American Inns of Court Bankruptcy Distinguished Service Award, a national honor. Awesome Attorneys did not identify Drain on the State Bar of Arizona’s current Bankruptcy Law Certified Specialists roster; one fellow attorney’s review references a “certified bankruptcy specialist” credential, but Awesome Attorneys is not treating that secondhand reference as independently confirmed and is not using the word “specialist” for Drain on that basis.
The Arizona Legal Backdrop
What follows is general legal information, not legal advice.
Consumer bankruptcy in Arizona proceeds primarily under federal law (Title 11 of the U.S. Code), with Chapter 7 liquidation and Chapter 13 wage-earner reorganization the two most common consumer filings. Arizona allows debtors to choose between federal and state property exemptions when filing, a choice that can significantly affect what property a filer keeps. Foreclosure defense, another named focus area, intersects with Arizona’s trustee-sale statute, A.R.S. § 33-807 et seq.
The Awesome Attorneys Assessment
Diane L. Drain Phoenix’s clearest differentiator is four decades of bankruptcy practice combined with a genuine mentorship track record within the Arizona bankruptcy bar and a 2025 national service award — credentials that speak to standing within the profession rather than just years in practice.
The honest trade-off: Awesome Attorneys did not find Drain listed on the State Bar of Arizona’s current Bankruptcy Law Certified Specialists roster, so clients specifically seeking that particular credential should verify current certification status directly with the firm rather than relying on secondhand references.
