When a loved one passes away, family members are often surprised to discover that someone must take responsibility for managing the deceased person’s financial affairs. In some cases, that person is either an executor or a trustee. Many people use these terms interchangeably even though they perform different roles and responsibilities.
Understanding the difference can help families navigate estate administration and avoid costly mistakes during an already difficult time.
What Is an Executor?
An executor is the person responsible for administering a deceased person’s estate through the probate process. If the deceased person left a will, the will often names the executor who will serve after death.
The executor performs the duties required under the law and the decedent’s estate plan. These responsibilities may include locating and inventorying estate assets, identifying outstanding debts and liabilities, filing necessary court documents, paying valid creditor claims, managing and preserving estate property, filing required tax returns and distributing assets to beneficiaries in accordance with the will or applicable law. The executor serves as the estate’s fiduciary and is expected to act in the best interests of the estate and its beneficiaries.
Because probate is a court-supervised process, the executor often works closely with attorneys, accountants, appraisers and the court system.
What Is a Trustee?
A trustee manages assets held in a trust. When the creator of a living trust dies, the successor trustee takes over and administers the trust according to the trust document. Unlike an executor, a trustee often operates outside of probate court.
A trustee administers the trust and manages its assets according to the terms of the trust document. These duties may include overseeing and protecting trust assets, maintaining real estate owned by the trust, communicating with beneficiaries, gathering and organizing financial records, paying trust expenses and obligations, filing required tax returns and distributing trust property to beneficiaries as directed by the trust.
The trustee has a fiduciary duty to act in the best interests of the beneficiaries, exercise reasonable care and diligence, and faithfully follow the instructions set forth in the trust document.
Why Some Estates Have Both
Many people are surprised to learn that an estate can involve both an executor and a trustee. This situation commonly arises when assets are owned by a trust while other assets remain outside the trust and are subject to probate. In these cases, the trustee is responsible for administering and distributing the trust assets according to the terms of the trust, while the executor manages the probate estate, including gathering assets, paying debts and distributing property that was not transferred into the trust during the decedent’s lifetime. As a result, both individuals may play important but distinct roles in the overall estate administration process.
For example, this often occurs when assets are titled differently at the time of death. A parent may have placed their home into a living trust but left a personal bank account titled only in their individual name. The home would typically be administered by the trustee, while the bank account would require probate and administration by the executor.
In situations like this, family members may need to work with both the trustee and the executor to address various aspects of the estate. This is one reason estate administration can become more complicated than families expect.
Executor vs. Trustee Authority
Neither role is necessarily more powerful. They simply have authority over different assets.
An executor has authority over assets that are part of the probate estate, and a trustee has authority over assets owned by the trust.
Determining which assets belong to the probate estate and which are held by the trust is often one of the first and most important tasks following a death.
Fiduciary Duties and Personal Liability
Both executors and trustees can potentially be held personally liable because these roles carry significant fiduciary responsibilities. Because they are legally required to act in the best interests of the estate or trust and its beneficiaries, certain mistakes may result in personal liability. Examples include distributing assets too early before obligations are satisfied, failing to pay required taxes, ignoring valid creditor claims, mismanaging or imprudently investing assets, treating beneficiaries unfairly or failing to maintain accurate and complete records. However, these risks can be avoided through professional guidance, diligent administration and thorough documentation.
Tax Responsibilities for Executors and Trustees
In other cases, the deceased person’s final individual income tax return must be filed to report income earned up to the date of death. Additionally, a trust may be required to file its own income tax return if it meets certain filing thresholds or generates taxable income. An estate may also have separate tax filing obligations during the administration period, depending on its size and activity.
Beyond income tax filings, there may be important property tax considerations, particularly in states like California, where rules such as Proposition 19 and reassessment provisions can affect inherited real estate. If inherited assets are later sold, capital gains tax planning and accurate basis calculations also become important in determining potential tax liability.
With multiple tax considerations potentially affecting an estate or trust, many fiduciaries are surprised by the complexity and the filing requirements and planning decisions involved in the administration process.
Can a Family Member Serve as Executor or Trustee?
A family member can serve in these roles, and it is common for individuals to name adult children, siblings, other trusted relatives or close friends as executors or trustees. However, it is important to recognize that willingness to serve and the ability to handle the responsibilities are not always the same.
Serving as an executor or trustee can involve significant administrative, financial and tax-related duties, which can become complex depending on the size and structure of the estate or trust. For this reason, some families choose to appoint a professional fiduciary, especially when the estate is large, complicated or involves sensitive family dynamics.
What Affects the Administration Timeline?
The length of estate or trust administration varies widely, and no single timeline applies to every situation. The duration typically depends on several factors, including the overall complexity of the estate, the number of beneficiaries involved, the types of assets being managed and whether real estate holdings require valuation or sale.
Additional considerations such as tax obligations, outstanding creditor claims and the presence of family disputes can also significantly extend the process. As a result, some estates and trusts can be settled quickly, while others can take longer to administer depending on the circumstances involved.
Common Estate and Trust Administration Mistakes
Executors and trustees can make a range of avoidable mistakes during estate and trust administration. These include failing to gather complete financial and legal records, making distributions to beneficiaries too early, overlooking required tax filings or ignoring important basis valuation issues that can affect future capital gains.
Other common errors include neglecting property tax consequences, failing to maintain clear and consistent communication with beneficiaries, improperly mixing personal funds with estate or trust assets or selling inherited property without fully understanding the tax implications. Fortunately, many of these issues can be prevented through proactive planning, careful recordkeeping and guidance from qualified legal and tax professionals.
