Private Agreements Among Heirs: Changing How an Estate Is Divided

Verified April 4, 2026 • 57th Legislature, 1st Regular Session

Arizona allows heirs and beneficiaries to agree among themselves to change how estate assets are divided, even if the will or intestacy law says otherwise. As long as creditors and tax obligations are satisfied, the personal representative must follow the agreement.

Title 14, PROBATE OF WILLS AND ADMINISTRATION

azleg.gov

When Heirs Want to Divide Things Differently

A will might leave everything equally to three children. But those children may have their own preferences. One wants the house. Another wants the investment accounts. The third prefers cash. This statute gives them the flexibility to work it out on their own terms.

Subject to the rights of creditors and taxing authorities, competent successors may agree among themselves to alter the interests, shares, or amounts to which they are entitled under the will of the decedent or under the laws of intestacy, in any way that they provide in a written contract executed by all who are affected by its provisions.

A.R.S. § 14-3912

The agreement must be in writing and signed by every person whose share is affected. Once that is in place, the personal representative is bound to follow the agreement when distributing estate assets. This gives families the power to tailor distributions to their actual needs rather than relying on a rigid formula.

Important Limits on These Agreements

The flexibility is not unlimited. Creditors and taxing authorities come first. No private agreement among heirs can reduce what creditors are owed or avoid estate taxes. The personal representative still has a duty to pay all debts, taxes, and administrative expenses before honoring the agreement.

The agreement also cannot affect successors who are not parties to it. If a trust is created under the will, the trustee is treated as a successor for purposes of this statute, but the trustee still owes fiduciary duties to trust beneficiaries. A private agreement cannot override those duties.

When family members are on good terms and willing to communicate openly, this statute provides a practical tool for avoiding the cost and delay of formal court proceedings. Partner attorneys can help draft these agreements to make sure they satisfy legal requirements and protect everyone involved.

14-3912. Private agreements among successors to decedent binding on personal representative Subject to the rights of creditors and taxing authorities, competent successors may agree among themselves to alter the interests, shares, or amounts to which they are entitled under the will of the decedent or under the laws of intestacy, in any way that they provide in a written contract executed by all who are affected by its provisions. The personal representative shall abide by the terms of the agreement subject to his obligation to administer the estate for the benefit of creditors, to pay all taxes and expenses of administration, and to carry out the responsibilities of his office for the benefit of any successors of the decedent who are not parties. Personal representatives of decedents' estates are not required to see to the performance of trusts if the trustee thereof is another person who is willing to accept the trust. Accordingly, trustees of a testamentary trust are successors for the purposes of this section. This section does not relieve trustees of any duties owed to beneficiaries of trusts.

Related Questions

What is probate, and how long does it take in Arizona?

Probate is a court-supervised process that validates a will, pays debts, and distributes assets. In Arizona, it typically takes 8 to 12 months and costs $10,000 to $15,000 in fees.

How can I prevent family conflict over my estate plan?

The most effective way to prevent conflict is to put your intentions in writing with clarity. Spell out who receives what, who manages the estate, and explain your reasoning if shares are unequal.

Why isn't leaving assets equally to my children always fair?

Equal shares can create unequal results, especially with real estate. A trust defines exactly how assets are valued, divided, and managed so the split is fair and workable for everyone.
