Why people hire Siesco Law
In a high-asset divorce the legal mechanics are only half the battle. The other half is the financial work: business valuations, executive compensation, retirement account characterization, real estate appraisals, and tax modeling. Siesco Law has been running this kind of work for more than four decades. Robert Siesco is a Certified Family Law Specialist and Fellow of the American Academy of Matrimonial Lawyers — credentials held by only a small fraction of Arizona family lawyers.
Why This Firm
Siesco Law Office is one of the few Phoenix family law firms specifically built around high-asset and complex divorce. Robert E. Siesco Jr. is one of approximately 1,650 attorneys nationwide who are Fellows of the American Academy of Matrimonial Lawyers, and he is a Board-Certified Family Law Specialist. He has been selected to Arizona Super Lawyers in multiple years. The practice is now a father-son operation — Robert and Aaric Siesco — and includes high-net-worth divorces, same-sex marriage cases, and prenuptial and post-nuptial contracts. If your case involves a closely held business, executive compensation, significant real estate, or 7-figure-and-up assets, this is one of the deepest benches in Phoenix.

Client Reviews
“Robert handled my divorce when my spouse and I owned a closely held business together. He coordinated the valuation, characterized everything correctly, and we ended up with a clean split that didn't blow up the company.”
“He was direct that mediation was a better path than litigation given our facts. We saved months and legal fees and ended with an outcome both sides could accept.”
“As a same-sex couple we wanted a firm that had handled the specific issues that come up. Aaric understood the issues and we never had to explain anything twice.”
