The Uniform Probate Code, or UPC, is a model law drafted by the Uniform Law Commission to standardize how states handle wills, intestate succession, and estate administration. States may adopt all, part, or none of it, so it functions as a widely referenced template rather than a binding federal law.
Regardless of whether your state has adopted the UPC, a properly executed will still gives you the most control over how your estate is handled. Build your online will with FastWill to make sure your document meets your state's actual requirements.
Why the UPC Exists
The Uniform Law Commission, formerly known as the National Conference of Commissioners on Uniform State Laws, drafted the UPC to reduce the inconsistency between state probate systems. Its goal is to give courts, executors, and families a more predictable path through intestate succession, will validation, and estate administration, whichever state the estate happens to be in.
What the Code Covers
The UPC is organized into several major articles, each addressing a distinct part of probate law.
- Article I, General Provisions: defines core terms like intestate, personal representative, and executor.
- Article II, Intestacy and Wills: governs how property is distributed when there is no will, and sets rules for creating, interpreting, and revoking wills.
- Article III, Probate and Administration: details how a will is validated and an estate administered, including both supervised and unsupervised options.
- Article IV, Foreign Personal Representatives: addresses estates with property in more than one state and when ancillary probate is required.
- Article V, Protection of Persons Under Disability: covers guardianship for minors and incapacitated adults.
- Article VI, Nonprobate Transfers: explains how joint accounts, payable-on-death, and transfer-on-death designations pass outside probate.
How the Code Has Changed Over Time
First published in 1969, the UPC has been revised multiple times, including major updates in 1990, 1993, and 2019, to modernize language and align with related uniform laws such as the Uniform Parentage Act. Each revision reflects how estate planning practices and family structures have evolved since the original draft.
Which States Have Adopted It
Roughly 18 states have adopted the UPC in whole or in significant part, though the exact list shifts as legislatures update their own probate codes, and many more states have borrowed specific provisions without adopting the code wholesale. Because adoption is never guaranteed or complete, you cannot assume the UPC governs your estate just because your state is generally associated with it.
Where to Find the Actual Text
The full UPC text is published and maintained by the Uniform Law Commission. If your state has adopted some or all of the UPC, your state's own probate code, usually published by the state legislature, will show exactly which provisions apply and how they may have been modified from the model language.
Supervised vs. Unsupervised Administration Under the UPC
One practical feature the UPC introduced is the choice between supervised and unsupervised estate administration. Unsupervised administration lets an executor handle most steps, inventorying assets, paying debts, and distributing property, without going back to court for approval at every stage, which speeds up simple, uncontested estates considerably. Supervised administration keeps the court involved at each major step and is typically reserved for estates with disputes, unclear documents, or beneficiaries who cannot agree. States that have adopted this part of the UPC generally let the executor or an interested party request whichever track fits the estate's actual needs.
A Worked Example: Executor Choices in an Adopting State
Say a UPC state resident dies with a simple will naming an adult child as executor, leaving a house, a checking account, and no significant disputes among heirs. Because that state has adopted the UPC's unsupervised administration option, the executor can petition for it directly, then move through the process without returning to court after each step: filing an inventory, notifying known creditors, paying valid debts, and distributing what remains according to the will. If a sibling later disputes the executor's accounting, the case can shift to supervised administration, meaning the court reviews each subsequent action before it happens. This flexibility, letting simple estates move quickly while complex ones get more oversight, is one of the practical reasons the Cornell Law School Legal Information Institute describes the UPC as covering estate administration, intestacy, wills, nonprobate transfers, and guardianship matters in a single, cross-referenced framework.
Why This Matters for Your Will
Whether or not your state uses the UPC, your will still needs to meet that state's specific signing, witnessing, and notarization rules to be valid. A document written around a generic template, rather than your actual state's requirements, is exactly the kind of thing that ends up delayed in probate court.

Frequently Asked Questions
Is the Uniform Probate Code a federal law?
No. It is a model law that individual states can choose to adopt in whole, in part, or not at all.
Does my state automatically follow the UPC?
Not necessarily. Even states generally associated with the UPC may have modified specific provisions, so you need to check your state's actual probate code.
What does Article II of the UPC cover?
It governs intestate succession, meaning who inherits when there is no will, and sets rules for creating, interpreting, and revoking wills.
Where can I read the actual UPC text?
The Uniform Law Commission publishes and maintains the model text, and your state legislature's website will show any provisions it has adopted.
Does the UPC replace the need for a properly signed will?
No. Even in UPC states, your will still needs to meet your state's specific execution requirements to be valid and easy for the court to process.
Can an executor request supervised administration even if the estate qualifies for the faster track?
Yes. In most UPC-adopting states, either the executor or another interested party can ask the court for supervised administration if they want the added oversight, even when the estate would otherwise be eligible for unsupervised administration.
