Choosing between a will and a trust in Arizona comes down to a trade: a will is cheaper to create but sends your estate through public probate court, while a revocable living trust costs more upfront and avoids probate entirely, keeps your affairs private, and lets you control how and when beneficiaries receive their shares. Neither one is universally better. For a modest estate with a simple family picture, a will often does the job. For larger estates, blended families, beneficiaries who need protection from themselves or creditors, or anyone who values privacy, a trust usually earns its cost.
Quick Comparison at a Glance
A will takes effect only at death and must be validated by a Superior Court judge before anything moves. A trust takes effect the moment you sign and fund it, and the successor trustee can act immediately when you die without any court involvement.
A will becomes public record once filed for probate. A trust is a private document that generally never sees a courthouse. A will delivers assets in one lump transfer after debts are paid; a trust can hold and release assets in stages for years or decades. A will is simpler and cheaper to draft; a trust costs more and only works if you take the extra step of retitling your assets into it.
When a Will Is Enough in Arizona
Arizona has unusually generous small-estate shortcuts that let families skip formal probate without any trust at all. If the deceased person’s personal property is worth $200,000 or less after subtracting debts and liens, a successor can collect those assets using a signed affidavit presented to whoever holds the property, starting 30 days after death.1Arizona Legislature. Arizona Revised Statutes 14-3971 – Collection of Personal Property by Affidavit For real estate, a separate affidavit process applies when all Arizona real property owned by the deceased has a total assessed value of $300,000 or less after liens, based on the county assessor’s valuation rather than market price.
If your estate fits comfortably within those limits, a will plus the affidavit process can handle the whole transfer without a trust and without full probate. A simple will also works well when your family picture is uncomplicated: a single marriage, adult children you trust, no beneficiaries with addiction or creditor issues, and no particular need for privacy.
Even in the smallest estate, a will does something intestacy cannot. It names a guardian for minor children, picks the person who will administer the estate, and lets you leave property to unmarried partners, friends, stepchildren, or charities who would otherwise receive nothing.
When a Trust Is Worth the Cost
A revocable living trust pays off in four situations.
Privacy. A will filed for probate is a public document. Anyone can look up what you owned, who inherited it, and who is in charge. A trust stays private. Beneficiaries get the information they are entitled to, but the general public does not. Under Arizona law, the trustee must notify qualified beneficiaries within 60 days of taking the role or of the trust becoming irrevocable, and must provide at least an annual accounting of trust assets, income, expenses, and trustee compensation.2Arizona Legislature. Arizona Revised Statutes 14-10813 – Duty to Inform and Report Those disclosures go to the people with a stake, not the courthouse.
Staged distributions. A will transfers everything at once. A trust can hold assets and release them on a schedule you design, such as a third at 25, half the remainder at 30, and the balance at 35. You can also restrict distributions to education, housing, or medical costs. For a beneficiary who is young, inexperienced with money, or struggling, structured distributions can be the difference between a lasting inheritance and one that disappears quickly.
Spendthrift protection. Arizona trusts can include a spendthrift provision that blocks beneficiaries from pledging or transferring their interest and keeps most creditors away from trust assets until the trustee actually distributes them.3Arizona Legislature. Arizona Revised Statutes 14-10502 – Spendthrift Provision Once money is paid out to a beneficiary, it is theirs and creditors can reach it. The protection covers what is still inside the trust, not cash in a beneficiary’s account.
One boundary worth knowing: spendthrift protection does not shield the settlor’s own creditors. During your lifetime, assets in your revocable trust remain available to your creditors, and after death they can be used to pay your debts if the probate estate is short.4Arizona Legislature. Arizona Revised Statutes 14-10505 – Creditors Claim Against Settlor
Blended families and complex arrangements. Arizona is a community property state, and a surviving spouse’s intestate share depends on whether assets are community or separate and whether the deceased had children from a different relationship.5Arizona Legislature. Arizona Revised Statutes 14-2103 – Heirs Other Than Surviving Spouse; Share in Estate A trust lets you spell out exactly how a surviving spouse and children from a prior marriage share assets, in what order, and under what conditions.
What Probate Looks Like in Arizona
To decide whether avoiding probate matters, you need a picture of what probate actually involves. When someone dies with a will in Arizona, the will is filed in Superior Court, which validates it and appoints a personal representative to run the estate.6Arizona Legislature. Arizona Revised Statutes 14-3303 – Informal Probate; Proof and Findings Required There are two tracks. Informal probate moves with minimal court supervision. Formal probate is required when someone contests the will or multiple people want to serve as personal representative.
Informal probate for a straightforward estate usually takes six to eight months. Formal probate can stretch past a year. Either way, the estate must stay open at least four months to give creditors time to file claims, and the outer bar for pre-death creditor claims is two years from the date of death.7Arizona Legislature. Arizona Revised Statutes 14-3803 – Limitations on Presentation of Claims Final distributions to beneficiaries have to wait until the creditor window closes.
Filing fees start at a statewide base of $191, which includes a $15 document storage surcharge.8Arizona Judicial Branch. Superior Court Filing Fees Maricopa County charges $306 for an informal probate filing.9Maricopa County Clerk of Superior Court. Filing Fees Opposing petitions, post-judgment motions, and accounting reviews cost extra, so a contested estate accumulates significantly higher court costs.
A properly funded trust skips all of this. The successor trustee named in the document steps in on day one, pays debts, and distributes assets on the schedule the trust specifies. No court appointment, no filing fees, no mandatory waiting period tied to the court’s calendar.
What a Trust Requires to Actually Work
A trust only governs property that has been retitled in the trust’s name. That means recording new deeds for real estate, changing ownership on bank and brokerage accounts, and reassigning any other titled asset to the trustee. Anything you leave in your individual name at death falls outside the trust and may need to go through probate.
This funding step is where plans fall apart. People pay to have a trust drafted, sign the document, and never move their house or accounts into it. The result is the worst of both worlds: trust-level fees during life and probate at death anyway.
Most Arizona estate plans pair the trust with a pour-over will. A pour-over will is a short backup document that catches any asset you forgot to transfer into the trust and directs it there after death. It does not avoid probate for those caught items; they still pass through court before reaching the trust. Treat the pour-over will as a safety net, not a substitute for actually funding the trust.
Keep in mind that under Arizona law a trust is presumed revocable unless the document says otherwise, and a revocable trust lets you amend terms, change beneficiaries, pull assets back out, or dissolve the trust entirely while you are alive. For married couples with community property in the trust, either spouse can revoke their share, but amendments require both spouses to agree.10Arizona Legislature. Arizona Revised Statutes 14-10602 – Revocation or Amendment of Revocable Trust
Taxes
Arizona has no state estate tax and no inheritance tax. Heirs owe the state nothing for receiving an inheritance, whether the assets pass through a will or a trust. The choice between the two documents will not change your Arizona tax bill.
Federal estate tax is a separate issue, and it reaches very few Arizona families. The 2026 federal estate tax exemption is $15,000,000 per individual, and the 2026 annual gift tax exclusion is $19,000 per recipient.11Internal Revenue Service. What’s New – Estate and Gift Tax Married couples who plan carefully can effectively double the exemption.
While you are alive, a revocable trust is invisible for income tax purposes. You use your own Social Security number for trust accounts and report trust income on your personal return. After your death the trust becomes irrevocable, gets its own Employer Identification Number, and the trustee files a separate trust tax return.
If You Do Nothing
If you die without either document, Arizona’s intestacy statute controls. Property passes to your closest surviving relatives in a fixed order: surviving spouse first, then descendants, then parents, then siblings. The court picks who administers your estate and, if you have minor children, who raises them. Unmarried partners, close friends, stepchildren you did not adopt, and charities receive nothing. Even a basic will prevents those outcomes, which is why the real question for most Arizonans is not whether to have an estate plan, but whether a will alone is enough or whether a trust earns its keep.
