Arizona Estate Planning for Blended Families

In a blended family — where one or both spouses have children from a prior relationship — Arizona's default rules create a direct conflict between your surviving spouse and your biological children. Without an explicit plan, one group wins and the other loses.

What Arizona Intestacy Does to Blended Families

Under A.R.S. § 14-2102, if you die without a will and have children who are not also your surviving spouse's children, Arizona splits your estate:

• Your community property: Surviving spouse gets 50% (their existing share). Your 50% is split between your children from the prior relationship.
• Your separate property: Surviving spouse gets 50%. Your children get 50%.

This sounds reasonable on paper. In practice, it often forces the sale of the family home. If the house is community property and your children inherit half of your share, your surviving spouse may need to buy them out or sell.

Worse: if your spouse survives you and then remarries or simply writes a will leaving everything to their own children, your biological children get nothing more — only the intestacy share they already received.

The "I'll Leave Everything to My Spouse" Problem

Many blended-family couples write simple wills leaving everything to each other, assuming the surviving spouse will "do the right thing" and pass assets to both sides' children. This fails for predictable reasons:

• The surviving spouse remarries and their new spouse becomes the primary beneficiary
• The surviving spouse's own children exert pressure ("Mom, you should leave the house to us — his kids already got their share")
• The surviving spouse lives another 20 years and needs the assets for care, leaving nothing

Once you die, you lose all control. A will that says "everything to my spouse" gives your spouse zero legal obligation to your children.

Tools That Protect Both Sides

Life estate deed or trust with remainder beneficiaries. Your spouse gets the right to live in the home for their lifetime. When they die, the property passes to your designated beneficiaries (your children). Your spouse can't sell it, mortgage it, or redirect it.

A revocable living trust with specific distribution terms. The trust can provide income or housing to your surviving spouse while preserving the principal for your biological children. Common structures:

• QTIP trust (qualified terminable interest property): spouse gets income from assets during their lifetime; remainder passes to your designated heirs
• "Shelter in place" provision: spouse can live in the home until death or voluntary departure; property then distributes to your children

Beneficiary deed with your children as grantees. If you want your home to bypass your spouse entirely and go directly to your children, a beneficiary deed accomplishes this. But consider whether this leaves your spouse without housing.

Separate property agreements. A written agreement documenting which assets are separate property (premarital assets, inheritances) prevents commingling claims. Arizona presumes assets acquired during marriage are community property — the burden of proving separate property status falls on whoever claims it.

The Community Property Trap

In Arizona, income earned during the marriage is community property. If one spouse uses their paycheck to make mortgage payments on a home they owned before the marriage, the community may acquire an interest in that home's appreciation. This Dragotti claim can complicate what you thought was separate property.

The fix: a prenuptial or postnuptial agreement clearly defining what stays separate. Without written documentation, community property presumptions apply.

Practical Steps for Blended Families

1. Never rely on intestacy — Arizona's default splits don't align with most blended families' intentions
2. Never rely on a simple "everything to my spouse" will — it eliminates your children's inheritance
3. Title the home carefully — CPWROS gives your spouse 100% automatically; consider whether that's actually what you want
4. Name contingent beneficiaries on retirement accounts and life insurance — "my spouse, then my children" ensures your kids aren't accidentally excluded
5. Document separate property — keep records of premarital assets, inheritance deposits, and any property agreements
