Will vs Trust: Quick Answer
A will is a legal document that directs how your assets are distributed after death through the probate process. A trust is a legal entity that holds assets and can distribute them according to your instructions — often without probate. Most Arizona residents with significant assets, real estate, or blended families benefit from a revocable living trust. Those with simpler estates may only need a will, beneficiary designations, and a transfer-on-death deed.
Neither a will nor a trust alone constitutes a complete estate plan. Both should be paired with powers of attorney, healthcare directives, and properly maintained beneficiary designations.
Side-by-Side Comparison
| Feature | Will | Revocable Living Trust |
|---|---|---|
| Probate | Required — goes through court process | Avoids probate for assets titled in the trust |
| Cost to create | $300-$1,000 (attorney-drafted) | $1,500-$3,000+ (attorney-drafted) |
| Privacy | Public record (probate filings) | Private — not filed with any court |
| Effective when | Only at death | During life and at death |
| Incapacity planning | Does not address incapacity | Successor trustee manages assets if you’re incapacitated |
| Speed of distribution | Months to years (probate timeline) | Days to weeks after death |
| Contestability | Can be contested in probate court | More difficult to contest than a will |
| Ongoing maintenance | Minimal | Must re-title assets into the trust; periodic review |
| Out-of-state property | Requires separate probate in each state | Avoids ancillary probate in other states |
| Revocability | Revocable until death | Revocable during your lifetime (if revocable trust) |
| Tax benefits | None | None for revocable trusts (irrevocable trusts may reduce estate taxes) |
| Best for | Simple estates, younger individuals, those without real estate | Homeowners, blended families, privacy-conscious, multi-state property owners |
Which Do You Need? Decision Matrix
| Your Situation | Recommended Tool | Why |
|---|---|---|
| Single, few assets, no real estate | Will only | Low cost, simple estate, beneficiary designations handle accounts |
| Young parents with minor children | Will + testamentary trust provision | Will names guardians; testamentary trust manages assets for children |
| Own a home in Arizona only | Will + beneficiary deed | Beneficiary deed avoids probate on the home without trust cost |
| Own property in Arizona and another state | Revocable living trust | Avoids probate in both states (ancillary probate is costly) |
| Blended family (children from prior marriage) | Revocable living trust | Controls distribution timing; protects children’s inheritance |
| Value privacy over your estate details | Revocable living trust | Trust is private; wills become public record through probate |
| Concerned about incapacity planning | Revocable living trust + POA | Successor trustee manages assets without court conservatorship |
| Estate over $13.61M (federal estate tax threshold) | Irrevocable trust | Removes assets from taxable estate |
| Need Medicaid asset protection | Irrevocable trust (5+ years before need) | May protect assets from Medicaid spend-down with proper timing |
| Want staggered distributions to heirs | Trust (revocable or testamentary) | Sets age thresholds or conditions before heirs receive assets |
Arizona Probate: Costs and Timeline
| Factor | With a Will (Probate) | With a Revocable Trust |
|---|---|---|
| Timeline | 6-18 months | Days to weeks |
| Attorney fees | 2-5% of estate value | One-time setup ($1,500-$3,000) |
| Court filing fees | $300-$500+ | None |
| Privacy | Public record | Completely private |
| Out-of-state property | Separate probate per state ($2,000-$5,000+ each) | No additional cost |
| Incapacity coverage | None (requires separate conservatorship) | Built-in via successor trustee |
| Example: $500,000 estate | $10,000-$25,000 in probate costs | $1,500-$3,000 upfront |
When a Will Is Sufficient
Simple Estates
If your assets consist primarily of retirement accounts (IRAs, 401(k)s) and bank accounts that can pass via beneficiary designations, a will may be all you need. The will covers any residual assets and names guardians for minor children.
Limited Real Estate
If you own one home in Arizona and no property in other states, a will combined with an Arizona beneficiary deed (transfer-on-death deed) can avoid probate on the home without the cost of a trust.
Cost Sensitivity
A properly drafted will costs $300-$1,000, compared to $1,500-$3,000+ for a trust. For individuals or couples with straightforward situations and limited assets, a will provides adequate protection at lower cost.
Young Families
Young parents primarily need a will to name guardians for minor children — trusts cannot appoint guardians. A will can include a testamentary trust provision that creates a trust upon death to manage assets for minor children, combining both tools.
When a Trust Is Better
Probate Avoidance
Arizona probate can take 6-18 months and costs approximately 2-5% of the estate’s value in attorney fees and court costs. A revocable living trust bypasses probate entirely for assets titled in the trust, saving time and money.
Arizona does offer a “small estate” simplified probate for estates under $75,000 in personal property and $100,000 in real property, but most retirees exceed these thresholds.
Privacy
Wills become public record when filed with probate court. Anyone can look up the details of a probated estate — assets, beneficiaries, debts, and family disputes. Trusts remain private.
Incapacity Planning
A will does nothing if you become incapacitated but are still alive. A revocable living trust names a successor trustee who can immediately manage your assets without court intervention (like a conservatorship proceeding).
Blended Families
Trusts provide more control over how assets are distributed to children from multiple marriages. A trust can specify that your surviving spouse can use the assets during their lifetime, but that the remaining assets pass to your children from a prior marriage upon the spouse’s death — something that’s difficult to enforce with a will alone.
Multi-State Property
If you own property in Arizona and another state, a will would require probate in both states (called “ancillary probate”). A trust titled to property in both states avoids probate entirely in both jurisdictions.
Control Over Timing and Conditions
Trusts allow you to specify conditions for distribution — age requirements, educational milestones, matching provisions, or staggered distributions. A will distributes assets outright at death, giving beneficiaries immediate, unrestricted access.
Revocable vs Irrevocable Trusts
| Feature | Revocable Trust | Irrevocable Trust |
|---|---|---|
| Can be changed | Yes, anytime during your lifetime | Generally no (with limited exceptions) |
| Asset protection | None — assets are still “yours” for creditor/lawsuit purposes | Yes — assets are removed from your estate |
| Estate tax benefits | None — assets counted in your estate | Yes — assets removed from taxable estate |
| Medicaid planning | No protection (counted as available asset) | May protect assets from Medicaid spend-down (with proper timing) |
| Income tax | You pay taxes on trust income (same SSN) | Trust pays taxes (often at higher rates) or income taxed to beneficiaries |
| Common uses | Probate avoidance, incapacity planning, privacy | Estate tax reduction, asset protection, Medicaid planning, charitable giving |
For most Arizona retirees, a revocable living trust is the right choice. Irrevocable trusts are primarily useful for high-net-worth individuals with estates approaching the federal estate tax exemption ($13.61 million per individual in 2026) or those with specific asset protection or Medicaid planning needs.
Arizona-Specific Estate Planning Considerations
Community Property State
Arizona is a community property state, meaning assets acquired during marriage are generally owned equally by both spouses. This has important implications:
- Full step-up in basis: When one spouse dies in a community property state, BOTH halves of community property receive a stepped-up cost basis — not just the deceased spouse’s half. This can eliminate significant capital gains liability.
- Example: A couple purchased a home for $200,000 that’s now worth $500,000. In a common-law state, only the deceased spouse’s half ($250,000) gets a step-up. In Arizona, the entire $500,000 value becomes the new basis, eliminating the $300,000 gain.
Arizona Beneficiary Deed
Arizona allows beneficiary deeds (transfer-on-death deeds) that automatically transfer real property to named beneficiaries upon the owner’s death — without probate and without a trust. This is a cost-effective alternative to trusting a home for probate avoidance. However, beneficiary deeds don’t provide incapacity protection or distribution control.
No Estate Tax
Arizona has no state-level estate or inheritance tax. Only the federal estate tax applies for estates exceeding $13.61 million per individual. This means most Arizona residents don’t need an irrevocable trust for tax purposes — but may still benefit from a revocable trust for probate avoidance and incapacity planning.
Arizona Trust Code
Arizona adopted the Uniform Trust Code with modifications (A.R.S. § 14-10101 et seq.), providing modern, flexible trust law. Key provisions:
- Trusts can be modified or terminated by court order if circumstances change
- Trustee duties and beneficiary rights are clearly defined
- Arizona trusts generally remain valid even if the grantor moves to another state
Essential Estate Planning Documents
A complete estate plan — whether built around a will or trust — should include:
- Will — distributes assets not in a trust, names guardians for minor children
- Revocable living trust (if applicable) — holds assets, avoids probate, provides incapacity management
- Financial power of attorney — authorizes someone to manage your finances if you can’t
- Healthcare power of attorney — designates a medical decision-maker
- Living will / advance directive — states your end-of-life care preferences
- Beneficiary designations — on all IRAs, 401(k)s, life insurance, and annuities (these override your will and trust)
- HIPAA authorization — allows healthcare providers to share medical information with designated individuals
Critical reminder: Beneficiary designations on retirement accounts and life insurance policies override whatever your will or trust says. If your IRA beneficiary form names an ex-spouse, that ex-spouse inherits — regardless of your will. Review all designations after every major life event.
Frequently Asked Questions
Do I need both a will and a trust?
If you have a revocable living trust, you still need a “pour-over will.” This is a simple will that directs any assets not already in the trust to be transferred (“poured over”) into the trust at death. It serves as a safety net for assets you may have forgotten to re-title into the trust.
How much does a trust cost in Arizona?
A revocable living trust drafted by an Arizona estate planning attorney typically costs $1,500-$3,000 for a couple, including the trust, pour-over wills, powers of attorney, and healthcare directives. Online trust services are available for $300-$800 but lack customization and may not address Arizona-specific issues like community property and beneficiary deeds.
Can I create a trust myself?
You can, but it’s generally not recommended for estates with significant assets, real estate, or complex family situations. DIY trusts may contain errors that aren’t discovered until death — when it’s too late to fix them. Common mistakes include failing to fund the trust (re-title assets), using incorrect legal language, and not addressing Arizona’s community property rules.
What is the biggest estate planning mistake?
Failing to update beneficiary designations is the single most common and costly estate planning error. Your IRA, 401(k), and life insurance beneficiary forms supersede your will and trust. If you named your ex-spouse 20 years ago and never updated the form, your ex-spouse inherits — even if your will says otherwise. Review all designations every 2-3 years.
Does a trust avoid estate taxes?
A revocable living trust does not reduce estate taxes — the assets are still part of your taxable estate. However, since Arizona has no state estate tax and the federal exemption is $13.61 million per individual, most Arizona residents have no estate tax liability regardless. Irrevocable trusts can remove assets from the taxable estate for those who need it.
