A working guide from The Scottsdale Signal newsroom — reviewed and revised on a rolling basis. Last reviewed May 2026.

Arizona's directed-trust statute and lack of a state estate tax have made Scottsdale one of the deepest trust-and-estate markets in the West. The bench is genuinely good — better, in many cases, than what coastal HNW families end up paying double for. The hard part is figuring out which firm is right for which kind of work.

Here's the working directory, organized by what you'd actually hire each one to do.

When you need a deep bench: the big firms

These are the AmLaw 200–scale practices with full-service tax, fiduciary, and corporate teams under one roof. You go here when the planning is complicated enough that you need a partner pulling in three other partners on the same morning.

Snell & Wilmer — Phoenix-headquartered, the deepest T&E bench in Arizona by a wide margin. Multigenerational wealth-transfer planning, family-business succession, dynasty trusts. The default choice for most $50M+ Scottsdale balance sheets. Senior-partner billing $850–$1,150.

Quarles & Brady — National firm, large Phoenix office, very strong on closely-held family business succession and on the messy end of fiduciary disputes. If your wealth is tied up in operating companies rather than marketable securities, Quarles is often the right call.

Greenberg Traurig — Phoenix office of the global firm. The choice for international or multistate UHNW exposure (foreign-grantor trusts, GRATs with cross-border beneficiaries, that sort of thing). Bills like a global firm.

Lewis Roca — Phoenix-headquartered. Strong on tax controversy alongside planning — useful if the IRS has shown interest in any prior return.

Bryan Cave Leighton Paisner — Phoenix office of the global private-client practice. Best for cross-border families with U.S. and EU situs trusts.

A complete planning engagement at any of these — refreshed estate plan, trust drafting, entity restructure, beneficiary designations — typically lands at $50K–$200K depending on complexity.

When you want focus: the boutiques

The dedicated T&E shops where the partners do the work themselves and the firm doesn't have a corporate department to subsidize.

Frazer Ryan Goldberg & Arnold — Phoenix-headquartered T&E boutique. Famously deep on fiduciary litigation. If a trust is being contested or a trustee is misbehaving, this is the call most Scottsdale CPAs make first. Senior partner billing typically $550–$800.

Burch & Cracchiolo — Phoenix; T&E plus business succession plus the messy adjacent litigation. Strong on tax-controversy crossover.

Tiffany & Bosco — Phoenix; T&E with a real-estate transfer specialty. Useful if your estate is concentrated in Arizona real property.

Provinziano & Associates — Scottsdale-based; the firm to call on prenuptial structuring, asset-protection trusts before marriage, and the family-law adjacent end of T&E. Founder Alphonse Provinziano is one of the most recognized practitioners in this niche in the Southwest.

A boutique planning engagement of equivalent scope to the big-firm number above typically lands at $35K–$120K.

What each one is actually best at

Multigenerational wealth-transfer planning (dynasty trusts, GRATs, IDGTs): Snell & Wilmer, Frazer Ryan, Greenberg Traurig.

Family business succession: Quarles & Brady, Snell & Wilmer.

Fiduciary litigation (will contests, trustee removal, beneficiary disputes): Frazer Ryan, Burch & Cracchiolo, Lewis Roca.

International or cross-border: Greenberg Traurig, Bryan Cave.

Asset-protection trusts and prenuptial structures: Provinziano, Frazer Ryan.

Real-estate-heavy estates: Tiffany & Bosco.

The trust-situs question — and why it matters here

Arizona's directed-trust statute is competitive with Delaware, South Dakota, and Nevada — but not identical. The actual decision tree:

Any T&E lawyer worth hiring will walk you through this trade-off honestly in the first meeting. Be wary of the ones who steer you toward Arizona reflexively without acknowledging the alternatives.

What to ask in the first meeting

How many UHNW families ($50M+) does your firm actively serve, not historically? What's your engagement structure — fixed-fee for the planning phase, hourly for ongoing administration? Do you draft Arizona Asset Protection Trusts in-house or refer them out? What's your view on Arizona vs. Nevada vs. Delaware situs for irrevocable trusts? Who covers if you're unavailable for a closing? Have you litigated against the trust company you're recommending I name as trustee?

That last one is the test. Any firm with a hidden referral relationship to a particular trust company will hesitate. The ones who answer cleanly are the ones to keep talking to.

How to use this list

Interview three. One big firm, one boutique, and one wild card from the second tier. Pay them all for the first hour rather than asking for free consultations — you'll get a sharper read on each, and the $1,500 you spend buys you a year of better decisions.

Bottom line: Arizona's T&E pricing is well below what equivalent partner-tier work costs in Manhattan, Palo Alto, or Greenwich. The bench is good. The mistake most newcomers make is choosing on firm name rather than on partner — interview the actual partner, not the firm.
