FAQ Summary
Married Arizona residents forming an LLC must choose how to title their membership interest — community property, community property with right of survivorship (CPWROS), or separate property — because Arizona presumes property acquired during marriage by an Arizona resident is community property unless the property was acquired as a gift or from inheritance or the couple signs a document that says the property is separate property.
That choice, backed by the right language in the Operating Agreement, determines whether a spouse's interest passes to the survivor automatically on the death of a spouse or must go through probate, and whether the surviving spouse gets a full step-up in income-tax basis.
This FAQ article walks through all three ownership forms, the exact steps and language needed for CPWROS or separate property treatment, what happens to the membership interest when a spouse dies, and why a revocable living trust is often the strongest option of all for avoiding probate at both deaths.

If you are a married Arizona resident forming a limited liability company, you face a question most people never think about: how will you legally own your LLC membership interest? The answer determines what happens to your membership interest when you die, whether your spouse has a legal claim to it, and whether your family will face probate.
This article explains the three ownership options for Arizona residents who are married to each other — community property, community property with right of survivorship, and separate property.
1. Arizona Is a Community Property State
Arizona is one of nine community property states in the United States. That fact has enormous legal consequences for any married person who acquires property — including an LLC membership interest — during the marriage.
Under Arizona law, there is a legal presumption that all property acquired by a married person during the marriage is community property. That presumption applies whether you intend it or not. If you do nothing to establish a different form of ownership, your LLC membership interest will be treated as community property by default.
The three forms of ownership a married Arizona resident can use for an LLC membership interest are:
Community Property
Both spouses own an undivided one-half interest. The default if you do nothing.
CPWROS
Community property that automatically passes 100% to the surviving spouse — no probate.
Separate Property
Belongs to one spouse alone. Requires deliberate, documented steps to establish.
Each has different legal consequences. Your choice must be deliberately stated in the LLC's Articles of Organization — and in some cases, must be backed up by a written agreement signed by both spouses.
2. Community Property
Community property is property owned jointly by both spouses. Each spouse owns an undivided one-half interest. Neither spouse owns a specific half — both own the whole thing together, each with a 50% stake.
Community property in Arizona generally includes any property acquired by either spouse during the marriage using marital earnings or community funds. It does not matter whose paycheck paid for it or whose name is on the title. If it was bought with community money during the marriage, it is presumed to be community property.
When one spouse dies owning community property, only the deceased spouse's one-half interest is part of that spouse's estate. That half must pass through the deceased spouse's estate plan — whether by revocable living trust, by will, or by Arizona's intestate succession laws if the person had neither. The surviving spouse already owns his or her own one-half interest and keeps it without going through probate.
3. Community Property With Right of Survivorship
Community property with right of survivorship — commonly abbreviated CPWROS — is a special form of marital co-ownership created by Arizona Revised Statutes § 33-431. It is available only to married couples.
During the marriage, CPWROS works exactly like regular community property. Each spouse owns an undivided one-half interest. The significant difference comes at death.
When one spouse dies, the deceased spouse's one-half interest automatically passes to the surviving spouse by operation of law — with no probate required. The surviving spouse becomes the sole 100% owner of the membership interest the moment the first spouse dies. Nothing needs to be filed in court. Nothing needs to go through the Arizona Superior Court probate system.
CPWROS also carries a major income-tax advantage. Because community property (including CPWROS) receives a full step-up in income-tax basis at the first death — not just the deceased spouse's half — the surviving spouse may sell appreciated assets with little or no capital gains tax exposure. This tax benefit is one reason CPWROS is often preferred over joint tenancy with right of survivorship for married couples in Arizona.
4. Separate Property
Separate property is property that belongs solely to one spouse. The other spouse has no ownership interest in it whatsoever. In Arizona, separate property includes:
- Property one spouse owned before the marriage
- Property one spouse received as a gift or inheritance during the marriage — even if received during the marriage
- Property acquired during the marriage entirely with separate property funds, provided those funds were never commingled with community funds
Separate property does not automatically pass to the surviving spouse at death. The owner of the separate property can leave it to anyone — a child from a prior marriage, a sibling, a charity — or it will pass by intestate succession if the owner dies without an estate plan.
Because Arizona law presumes that property acquired during a marriage is community property, a married person who wants to own an LLC membership interest as separate property must take deliberate, documented steps to overcome that presumption.
5. How a Married Couple Owns an LLC Membership as Community Property With Right of Survivorship
Owning an Arizona LLC membership interest as community property with right of survivorship requires two things:
- The couple must sign an Operating Agreement that states that their membership interest is "community property with right of survivorship."
- The membership interest must be funded with community property funds. If one spouse uses separate property to fund the LLC and the couple wants CPWROS treatment, a written transmutation agreement converting the separate property contribution into community property may be needed.
Arizona Revised Statutes § 33-431 requires that the intent to hold property as CPWROS be expressly stated in writing. Simply being married and putting both names on the membership is not enough.

6. How to Own an LLC Membership Interest as Separate Property
If a married Arizona resident wants to own his or her LLC membership interest as separate property — not subject to the non-member spouse's community property claim — the following steps are required:
- Fund the membership contribution entirely with separate property funds. If you use money earned during the marriage — which is community property — the membership will be treated as community property regardless of your intent. You must use funds that were yours before the marriage, or funds you received as a gift or inheritance, and you must not have commingled those funds with community money.
- Have the non-member spouse sign a written disclaimer or marital property agreement. Because Arizona law presumes community property, the safest way to establish separate property status is to have the non-member spouse sign a written, notarized agreement expressly disclaiming any community property interest in the LLC membership. This agreement is sometimes called a spousal disclaimer, a disclaimer deed, or a post-nuptial agreement. Without this signed disclaimer, the non-member spouse may later claim a community property interest in the LLC — especially in a divorce — and a court may agree.
- Keep records. Maintain documentation showing the source of the funds used to capitalize the LLC — bank statements, gift letters, inheritance records — so you can prove separate property status if it is ever challenged.
7. What Happens to the Membership Interest at Death
The form of ownership stated in the Articles of Organization determines what happens to the LLC membership interest when a member dies. Here is a plain-English summary:
| Form of Ownership | What Happens When a Spouse Dies | Probate Required? |
|---|---|---|
| Community property | Deceased spouse's one-half interest passes by will, by trust, or by intestate succession. Surviving spouse keeps his or her one-half. | Possibly — for the deceased spouse's half, if no trust |
| Community property with right of survivorship | Deceased spouse's one-half interest automatically passes to surviving spouse. Surviving spouse becomes 100% owner. | No |
| Separate property | 100% of the membership interest passes by the owner's will, trust, or intestate succession. | Possibly — if no trust |
| Revocable living trust | Trust controls distribution to successor beneficiaries per the trust terms. No probate at either death. | No |
8. Should a Trust Own the LLC Membership Instead?
For most married Arizona residents, the best answer to "how should we own our LLC membership interest?" is: through a revocable living trust. Here is why:
- Avoids probate at both deaths. A revocable living trust avoids probate when the first spouse dies and when the second spouse dies. CPWROS only avoids probate at the first death — when the surviving spouse later dies, the membership interest still passes through the survivor's estate, which may require probate.
- Provides for incapacity. If both spouses become incapacitated, the successor trustee named in the trust can manage the LLC membership without a court-appointed conservator.
- Controls who ultimately inherits. The trust lets you specify exactly who gets the membership interest, in what shares, and under what conditions — including whether a child's inheritance should be held in an asset-protected sub-trust rather than paid outright.
- Keeps the transition private. Probate is a public court proceeding. A trust transfer is private.
If you already have a revocable living trust — or if you are forming an LLC as part of creating your overall estate plan — have the trust listed as the member in the LLC's Articles of Organization from day one. Do not put the membership in your individual names and try to transfer it to the trust later. Get it right when the LLC is formed.
Frequently Asked Questions
Q1: If my spouse and I form an Arizona LLC together, are we automatically community property owners of the membership?
Yes.
Q2: Can I list just one spouse's name in the Articles even if the membership is community property?
You can, but it does not change the legal reality. Community property remains community property regardless of whose name appears on the title or in the Articles. The non-listed spouse still owns an undivided one-half interest under Arizona law.
Q3: My spouse has nothing to do with my LLC business. Does my spouse still own half of my membership interest?
If you formed the LLC during the marriage and funded it with community funds — typically wages earned during the marriage — then yes, your spouse legally owns an undivided one-half interest as community property, regardless of whether your spouse participates in the business. The only way to prevent this is to fund the LLC with separate property and obtain a signed spousal disclaimer before or at formation.
Q4: What is the difference between CPWROS and joint tenancy with right of survivorship?
Both avoid probate at the first death by automatically transferring the deceased spouse's interest to the surviving spouse. The income-tax difference is significant. With CPWROS, both spouses' halves receive a stepped-up income-tax basis at the first death, meaning the surviving spouse can sell the asset with little or no capital gains tax on pre-death appreciation. With joint tenancy, only the deceased spouse's half gets the step-up. For appreciated LLC membership interests, CPWROS is usually the better choice for married couples who want survivorship without a trust.
Q5: Can we change the form of ownership after the LLC is already formed?
Yes. You can amend the LLC's Operating Agreement to state that the couple owns their membership interest as CPWROS.
Q6: Does an Arizona LLC operating agreement also need to reflect the form of ownership?
Yes, ideally. The LLC's operating agreement should be consistent with the Articles of Organization and should identify the members and their ownership percentages and forms of ownership. Inconsistency between the Articles and the operating agreement creates ambiguity that can cause disputes.
Q7: What if I inherited money before the marriage and used it to form an LLC during the marriage?
Money you inherited before the marriage is your separate property. If you kept those inherited funds in a separate account that was never commingled with community funds, and you used only those funds to capitalize the LLC, the membership interest may qualify as your separate property. You should still get a signed spousal disclaimer and correctly state the separate property ownership in the Articles. If you have any doubt about whether the funds remained separate, consult an Arizona family law or estate planning attorney before forming the LLC.
Q8: Can a married person own just a portion of an LLC membership as separate property?
Yes. It is possible for part of a membership interest to be separate property and part to be community property — for example, if the member funded the initial capitalization with separate property and later made additional capital contributions from community earnings. This type of mixed-character ownership is complicated to track and prove. Meticulous records are essential. An Arizona attorney can help you structure and document the ownership correctly from the start.
