Duties and Responsibilities of a Trustee in Arizona

Arizona residents in cities like Surprise, Buckeye, Sun City West, and Peoria seeking to create a comprehensive estate plan often turn to trusts as a valuable tool. A trust is a legal arrangement that enables a trustee to hold and manage assets for the benefit of trust beneficiaries. Not only do trusts allow for the seamless transfer of the grantor’s assets to beneficiaries outside of probate, but they also afford greater privacy for surviving family members. The role of a trustee is crucial in this process, and it’s essential to understand the various duties and responsibilities they undertake.

What is a Trustee?

A trustee is an individual or entity appointed to hold and manage the assets placed within a trust. In the case of a revocable trust, the grantor typically serves as the initial trustee, allowing them to manage the trust assets while they are alive. However, upon the grantor’s passing, the trust often transforms into an irrevocable trust, and a successor trustee takes over the responsibility.

Trustees play a pivotal role in managing the trust’s assets and overseeing its operations. They are legally bound to act as fiduciaries, which means they must put the beneficiaries’ interests above their own. The duties of a trustee involve a high level of responsibility and adherence to legal and ethical standards. In Arizona, trustees are subject to the Arizona Trust Code (Title 14, Chapter 7, Article 1 of the Arizona Revised Statutes), which sets out specific requirements and guidelines for trust administration.

Duties of a Trustee

The role of a trustee comes with significant fiduciary duties, and they are legally bound to act in the best interests of the trust’s beneficiaries. The precise responsibilities may vary depending on the specific type of trust and the provisions outlined in the trust documents. However, generally, trustees are tasked with the following key responsibilities:

  1. Serve as a Fiduciary:
    A trustee’s fiduciary duty is one of the most critical aspects of their role. They must act with undivided loyalty, utmost good faith, and always in the beneficiaries’ best interests. This duty includes avoiding conflicts of interest and disclosing any potential conflicts that may arise.
  2. Safeguard the Trust Assets:
    Trustees must prudently manage and protect the trust’s assets. This involves prudent investment strategies, diversification, and regular reviews of the investment portfolio. Trustees should consider the beneficiaries’ needs, risk tolerance, and financial goals when making investment decisions.
  3. Administer the Trust:
    The day-to-day administration of the trust involves various tasks, such as maintaining accurate records, managing income and expenses, paying taxes, and distributing assets to beneficiaries as stipulated in the trust documents.
  4. Send Reports to the State and Beneficiaries:
    In Arizona, trustees are often required to provide periodic reports to both beneficiaries and regulatory authorities. These reports must detail the trust’s financial status, investment performance, and any changes in the trust’s administration.
  5. Execute the Grantor’s Wishes:
    The trust document outlines the grantor’s wishes and objectives for the trust. The trustee is legally obligated to adhere to these instructions and make decisions in line with the grantor’s intentions.
  6. Make Wise Investments:
    Trustees must be knowledgeable about financial markets and investment strategies. They should act prudently when making investment decisions, aiming to achieve a reasonable return while minimizing unnecessary risks.

The duties of a trustee can be complex and time-consuming. Trustees are expected to exercise sound judgment and diligence when managing the trust’s assets. They may need to seek professional advice, such as consulting with financial advisors, attorneys, or accountants, to ensure the trust’s assets are appropriately invested and protected. Furthermore, trustees must keep accurate records of all transactions, income, and expenses related to the trust for reporting purposes.

Choosing the Right Trustee

Given the substantial responsibilities involved in the role of a trustee, selecting the right person or institution is of utmost importance. Grantors may opt to serve as trustees themselves initially, providing them with a sense of control during their lifetime. However, considering the potential complexities of trust management, appointing a professional corporate trustee or a trust company might be a wise decision to ensure expert guidance and impartiality.

When choosing a trustee, grantors should consider factors such as the trustee’s financial acumen, experience in trust administration, and commitment to upholding their fiduciary duties. Family members or friends may be emotionally invested but may lack the necessary expertise. On the other hand, a corporate trustee, such as a bank or trust company, offers professional management, continuity, and objectivity. They have the knowledge and resources to handle intricate financial matters and ensure compliance with legal requirements.


In conclusion, trusts are valuable tools for Arizona residents in cities like Surprise, Buckeye, Sun City West, and Peoria to secure their estates and provide for their loved ones. When establishing a trust, choosing a trustworthy and capable trustee is vital to fulfilling the grantor’s wishes and ensuring the beneficiaries’ well-being. A knowledgeable and responsible trustee can navigate the intricacies of trust management, making the estate planning process more efficient and effective.

Remember, estate planning and trust management can be complex, so seeking the guidance of an experienced estate planning attorney is highly recommended. By working together with a knowledgeable professional, you can create a robust estate plan that safeguards your assets and provides for your family’s future.
