In Loving Memory: Honoring the life and legacy of our esteemed partner, Lawrence ‘Larry’ Scaringelli
Phoenix trust and estate litigation lawyer helping families resolve disputes

Downtown Phoenix blends history and growth, from the preserved Orpheum Theatre’s 1929 Spanish Baroque design to the skyscrapers that house Arizona’s most prominent financial institutions. Families here build legacies with the same care, only to see them threatened by disputes over trusts and estate disputes. That’s why a trust and estate litigation lawyer is essential. 

At Theut Scaringelli & Kupiszewski P.L.C., our seasoned litigators guide clients through every stage of these disputes. With decades of experience in the Maricopa County Superior Court, our attorneys combine courtroom knowledge with a compassionate approach. We steer Phoenix families through Arizona’s probate system, protect inheritances, enforce fiduciary duties, and safeguard property rights at every stage.

What Role Do Phoenix Trust Attorneys Play in Arizona?

A trust attorney blends legal authority with practical judgment. They interpret documents, challenge improper clauses, and defend rightful beneficiaries. Arizona law requires fiduciaries to act in the best interests of those they serve, and courts enforce that duty strictly. A skilled litigator exposes violations and pursues remedies. For families, this role turns overwhelming disputes into manageable steps.

What Types of Cases Does a Trust and Estate Litigation Lawyer Handle?

Disputes rarely arise from paperwork alone. They begin with people—siblings at odds, beneficiaries worried about exploitation, or fiduciaries facing accusations. Some common cases we see include:

  • Contested wills—challenges to validity based on undue influence, lack of capacity, or defective execution;
  • Trust disputes—disagreements about interpretation, trustee conduct, or distributions;
  • Fiduciary claims—allegations that a personal representative, trustee, or conservator failed in their duty;
  • Financial exploitation cases—misuse of accounts or property, including claims under the Arizona Adult Protective Services Act; and
  • Breach of contract and related claims—tied to family agreements about inheritance or property.

Each case requires an understanding not only of statutes, but also of how Phoenix probate judges view contested matters. Our attorneys have appeared before those judges for decades, bringing insight into what arguments resonate and how to shape a strategy that protects both assets and relationships.

How Do Trust Litigation Lawyers Protect Families?

Every family arrives with unique facts, but common themes repeat: grief, fear of loss, and frustration when communication breaks down. A phoenix estate lawyer protects families by:

  • Investigating financial records to uncover hidden transfers or exploitation;
  • Filing petitions promptly to preserve claims before statutes of limitation close;
  • Negotiating with opposing parties to reduce conflict and legal costs;
  • Presenting clear, evidence-based arguments to probate judges; and
  • Seeking remedies such as removing trustees, recovering stolen funds, or damages for breach of fiduciary duty.

This combination of speed and precision helps families regain stability while litigation proceeds.

How Does a Phoenix Estate Lawyer Help Beyond the Courtroom?

Sometimes litigation is unavoidable. At other times, parties settle disputes through mediation or negotiated agreements. At Theut Scaringelli & Kupiszewski, our lawyers guide clients toward the most effective course of action. That may involve:

  • Preparing for mediation to avoid protracted court battles,
  • Crafting settlement agreements that prevent future conflict, and
  • Advising fiduciaries on compliance to avoid liability.

By providing clients with both offensive and defensive tools, we protect families from unnecessary expenses and uncertainty.

Why Do Families Choose Theut Scaringelli & Kupiszewski P.L.C.?

  • Steve served ten years as a Superior Court Commissioner, presiding over probate and trust disputes; 
  • Jennifer built her career representing vulnerable adults and families through the Arizona Department of Economic Security and the Arizona Center for Disability Law; 
  • Paul and Larry merged long-running practices, later joining with Jennifer and Steve to create today’s firm; and 
  • Paul’s son, James, continues the legacy by providing legal counsel to families throughout the Phoenix area. 

Collectively, we’ve litigated thousands of guardianship, conservatorship, trust, and estate cases. Our reputation within the Maricopa County probate court means clients benefit from credibility built over years of experience.
