It’s one of the most common questions people ask when they start thinking about estate planning in Arizona: “Do I need a will or a trust?” Some people assume a will is enough. Others think a trust is only for wealthy people with mansions and stock portfolios.
The truth is somewhere in the middle. And in Arizona, the answer depends a lot on your specific situation: what you own, who you want to leave it to, and how much hassle you want to put your family through when you’re gone.
This blog breaks down both documents step-by-step so you can walk away knowing exactly which one fits your life. And if you want to go deeper on either, Modern Law’s estate planning team is available to help you figure it out.
Let’s Start Simple: What’s the Difference?
Before we get into which one you need, let’s make sure we’re on the same page about what these two documents actually are.
What Is a Will?
A will (officially called a Last Will and Testament) is a written document that tells the court what you want to happen to your stuff after you die. It kicks in only when you pass away. You can name a personal representative (that’s what Arizona calls the executor) to carry out your wishes, and if you have minor kids, you can name a guardian for them too.
In Arizona, a valid will requires you to be at least 18 years old and of sound mind. It must be signed in front of two witnesses who also sign it. This comes from ARS Section 14-2502, which is the core statute governing wills in Arizona.
Arizona also allows holographic wills, which are handwritten wills with no witnesses required, as long as the material portions and your signature are in your own handwriting. See ARS Section 14-2503 for the exact requirements. But fair warning: handwritten wills are easier to contest and often harder to enforce when things get complicated.
What Is a Living Trust?
A living trust (also called a revocable trust) is a legal entity that holds your assets while you’re alive. You create the trust, transfer your home, bank accounts, and investments into it, and name yourself as the trustee so you stay in full control. When you die, a successor trustee you chose takes over and distributes everything to your beneficiaries, no court required. Arizona trust law is governed by the Arizona Trust Code, ARS Title 14.
Unlike a will, a trust is active the moment you sign it. It is not just a death document. It also protects you if you become incapacitated, because your successor trustee can step in and manage your finances without a court appointing anyone.
Key Difference: A will is a set of instructions that goes into effect when you die. A trust is a living legal container that holds your assets and goes into effect the moment you create it.
Will vs. Trust in Arizona: Side by Side
| Feature | Will | Living Trust | Edge |
|---|---|---|---|
| Goes through probate? | Yes, almost always | No – skips probate entirely | Trust wins |
| Becomes public record? | Yes – anyone can read it | No – stays completely private | Trust wins |
| Covers incapacity? | No – only takes effect at death | Yes – successor trustee steps in | Trust wins |
| Cost to set up? | Lower – $300 to $1,000 | Higher – $1,500 to $5,000+ | Will wins |
| Names guardian for kids? | Yes | No – need a will for this | Will wins |
| Works immediately? | No – only after death | Yes – effective when signed | Trust wins |
| Requires funding? | No extra steps needed | Yes – must retitle assets | Will wins |
| Can be changed? | Yes – via a codicil | Yes – fully revocable while alive | Tie |
| Privacy level? | Low – public probate record | High – no public filing needed | Trust wins |
| Best for minor kids? | Yes – names guardian | Partial – use both together | Will wins |
The Big Reason People Choose a Trust: Probate
In Arizona, if you die with only a will, your estate almost always has to go through probate. That’s the court-supervised process where a judge validates your will and oversees the distribution of your assets. You can read how the Arizona probate process works directly on the Arizona Courts website.
Here is why probate is a problem for a lot of families:
- It takes time. Informal probate in Arizona typically takes 6 to 8 months minimum. There is a mandatory 4-month creditor notice period baked into the law, so no estate closes faster than that.
- It costs money. Court filing fees, attorney fees, and personal representative fees all add up.
- It’s public. Once your will is filed in probate court, anyone can walk in and read it. Your account balances, property values, and beneficiary names all become public record.
- It can cause conflict. Family members can challenge your will in probate court, leading to delays and legal battles.
A properly funded trust avoids all of that. Your successor trustee distributes your assets directly to your beneficiaries without a single court appearance. For a deeper look at how trusts handle succession, check out Modern Law’s article on who runs your trust when you’re gone.
What About Arizona’s Small Estate Shortcut?
Arizona does offer a simplified path called a small estate affidavit under ARS Section 14-3971. If your estate has personal property under $200,000 (updated threshold from HB 2116 in 2025) or real property under $300,000, your heirs can often skip formal probate using this affidavit. But once your estate goes above those thresholds, or if there’s any dispute among heirs, full probate kicks in.
If you own an Arizona home worth more than $300,000 (which describes most of the Phoenix metro and many other parts of the state right now), a trust is usually a much cleaner solution than relying on the small estate process.
When a Will Is Probably Enough
A will is not the inferior option. For a lot of people, it’s actually the right tool. Here’s when a will usually does the job:
- You’re young, renting, and don’t own much property yet. Your main concern is naming a guardian for your kids and making sure your personal belongings go to the right people.
- Your total estate is well under Arizona’s small estate affidavit threshold. If your assets are modest, probate may be quick and inexpensive enough that a trust isn’t worth the extra cost.
- You have minor children and need to name a guardian. A trust cannot do this. Only a will names a legal guardian for your kids if both parents die.
- You want to keep upfront costs low. A basic will costs $300 to $1,000 with an attorney. A full trust package can run $1,500 to $5,000 or more for an individual.
- You already have beneficiary designations on all major assets. If your retirement accounts, life insurance, and bank accounts all have named beneficiaries, those assets skip probate regardless of what your will says.
Important Reminder: Beneficiary designations on accounts like your 401(k), IRA, and life insurance always override your will. Make sure those designations are current. An outdated beneficiary is one of the most common and costly estate planning mistakes in Arizona.
When a Trust Is Worth the Extra Investment
A trust requires more upfront work and money, but it pays off for a lot of Arizona families. Here’s when a trust makes more sense than a will alone:
- You own real estate in Arizona. Property over $300,000 will go through full probate without a trust. Arizona home values have risen dramatically, so this applies to more families than ever. You can also use an Arizona beneficiary deed for a simpler option on a single property.
- You own property in multiple states. Without a trust, your family may have to go through probate in every state where you own real estate. A trust with your property inside avoids that entirely.
- You have a blended family. If you have children from a previous relationship and a current spouse, a trust lets you carefully control what each person receives and when. Modern Law has a great article on estate planning for blended families that covers this in detail.
- You value privacy. Your will becomes public record in probate. A trust stays completely private.
- You want to plan for incapacity. A trust lets your successor trustee manage everything if you have a stroke, accident, or illness before you die. A will does nothing until you’re gone.
- You want to control when beneficiaries receive money. A trust can hold assets for minor children until they turn 25, or release funds in stages rather than a lump sum. A will cannot do this.
- You want to minimize taxes. While Arizona has no state estate tax, smart trust planning can still reduce federal estate tax exposure for larger estates. See Modern Law’s blog on planning for purpose, not just taxes.
Most People Actually Need Both
This is the part most comparisons leave out. For the majority of Arizona homeowners and families, the best estate plan includes both a will AND a trust. Not one or the other.
Here’s how they work together:
- Your trust holds your major assets: your home, bank accounts, investment accounts, and anything with significant value. Those assets skip probate and go directly to your beneficiaries.
- Your will acts as a safety net: It is called a pour-over will, and it catches anything that did not make it into the trust before you died. When you die, those leftover assets get poured over into the trust.
- Your will names a guardian for your kids: A trust cannot do this. If you have minor children, you need a will specifically to name who takes care of them if both parents die.
Arizona courts actually recommend this combined approach for most families with real estate or dependents. The Arizona Judicial Branch self-service center has helpful resources on what triggers probate and how to avoid it.
Bottom Line: Think of a will as your foundation. A trust is the upgrade that saves your family time, money, and headaches. Most Arizona families with a home and kids benefit from having both.
Three Arizona-Specific Tools That Change the Equation
Arizona has some tools that other states don’t offer. These can sometimes replace the need for a full trust depending on your situation.
1. The Arizona Beneficiary Deed
Under ARS Section 33-405, Arizona allows you to record a beneficiary deed that transfers your real property to a named person when you die, without going through probate. You stay in full ownership while you’re alive. You can revoke it at any time. It’s one of Arizona’s most underused estate planning tools.

2. Community Property with Right of Survivorship
Under ARS Section 33-431, married couples in Arizona can title property as Community Property with Right of Survivorship (CPWROS). When one spouse dies, the surviving spouse automatically gets the whole property without probate, and they also get the double step-up in tax basis that can save significant money on capital gains taxes later.
3. Payable-on-Death and Transfer-on-Death Accounts
Bank accounts with a payable-on-death (POD) designation and investment accounts with a transfer-on-death (TOD) designation pass directly to your named beneficiary outside of probate. No trust or court needed. These are simple to set up and often overlooked.
Keep in mind that none of these tools replace a comprehensive estate plan. They’re great supplements, but they don’t cover incapacity planning, guardian nomination, or the full scope of what a well-drafted will and trust provide.
Frequently Asked Questions
Can I just use a will to avoid probate in Arizona?
Not on its own. A will almost always triggers probate in Arizona. To avoid probate, you need a funded living trust, beneficiary designations on accounts, a beneficiary deed for real property, or some combination of these tools.
Do I still need a will if I have a trust?
Yes. Even if you have a trust, you still need what’s called a pour-over will. It captures any assets that didn’t make it into the trust and also lets you name a guardian for minor children, something a trust cannot do.
What happens if I die with only a will in Arizona?
Your estate goes through probate. The Arizona courts supervise the distribution of your assets, it becomes public record, and your family waits months before receiving anything. If you own real property, the probate process involves the Arizona Superior Court in the county where the property is located.
How much does a trust cost vs. a will in Arizona?
A basic will with an attorney runs $300 to $1,000. A complete trust package (trust document, pour-over will, powers of attorney, and healthcare directive) typically costs $1,500 to $5,000 for an individual or $2,000 to $8,000 for a couple. The trust costs more upfront but often saves far more in probate costs and delays later.
Is a handwritten will valid in Arizona?
Yes. Arizona recognizes holographic wills under ARS Section 14-2503. But for anything beyond a very simple estate, a properly witnessed, attorney-drafted will is much safer and harder to challenge.
Can a trust be challenged in Arizona?
Yes. Both wills and trusts can be challenged in court. However, trusts are generally harder to contest than wills because they operate outside the public probate process.
What is a pour-over will?
A pour-over will is a short will that goes alongside your trust. When you die, it captures any assets that weren’t properly transferred into the trust and pours them into the trust, so everything gets distributed according to your trust’s instructions.
So Which One Do YOU Need?
Here’s a quick way to think about it:
- If you’re young, don’t own real estate, and have a simple financial picture: a will is a great starting point.
- If you own a home in Arizona, have kids, value privacy, or want to avoid putting your family through probate: a trust plus a pour-over will is the smarter move.
- If you have a blended family, own property in multiple states, or have a larger estate: a full trust-based plan is almost certainly what you need.
