Supplementary Principles of Law in Arizona Probate Proceedings

Verified April 4, 2026 • 57th Legislature, 1st Regular Session

When Title 14 does not specifically address a situation, Arizona courts can fill the gap using general principles of law and equity. This statute ensures that probate, trust, and protective proceedings are not stuck in rigid rules when broader legal principles provide a fair answer.

How Courts Fill Gaps in Title 14

No statute can anticipate every situation. Families, finances, and circumstances come in endless variations. A.R.S. 14-1103 addresses this reality with a single, direct rule: unless Title 14 has a specific provision that controls, general principles of law and equity apply.

Unless displaced by the particular provisions of this title, the principles of law and equity supplement its provisions.

A.R.S. § 14-1103

In practical terms, this means a court handling a probate matter, trust dispute, or guardianship case is not limited to what Title 14 says on the page. If the title is silent on a particular issue, the court can draw on established legal doctrines, equitable principles like fairness and good faith, and common law traditions.

Why This Matters in Real Disputes

Consider a situation where a trustee acts in bad faith but the specific trust provisions do not address the remedy. Without this statute, the court might be stuck. With it, the court can apply equitable principles to fashion a fair outcome. The same logic applies in estate disputes where the decedent's documents are incomplete or ambiguous.

The phrase "unless displaced" is important. If Title 14 has a specific rule that governs the issue, that rule controls. But where Title 14 is silent, courts are not left without tools. This keeps the system flexible and responsive to the real-world complexity of estate and protective proceedings.

Unless displaced by the particular provisions of this title, the principles of law and equity supplement its provisions.
