What Are the Duties of a Successor Trustee?

If you have been named as a successor trustee, this means a loved one trusted you deeply. It also means that after they pass away or can no longer manage their affairs, you will be responsible for their assets, which may include their house, bank accounts, and investments. You will also need to make sure the right people receive these assets. While many Naperville families use living trusts to avoid probate, that does not mean the work of administering the estate will go away. Instead, many of the duties shift to you as the trustee.

A successor trustee’s main duty is to manage the trust’s assets carefully and honestly for the benefit of the beneficiaries, following the instructions in the trust document while abiding by Illinois law. That includes locating and protecting assets, notifying beneficiaries, keeping clear records, paying valid bills and taxes, and distributing property as the trust directs. An experienced attorney can provide guidance on what steps must be followed during this process.

What Is a Successor Trustee?

With a trust, a person or institution will hold property for the benefit of others. The person who creates the trust is called the grantor or settlor. The beneficiaries are the people who will receive the trust assets. The trustee is the person in charge of managing the trust and distributing the assets.

In many living trusts, the grantor serves as their own trustee during their lifetime. The successor trustee is the person named to take over the trust when the grantor dies, becomes incapacitated, or steps down. When the grantor dies, the trust usually becomes irrevocable, which means it can no longer be changed.

What Law Governs Trustees in Illinois?

The Illinois Trust Code (760 ILCS 3/) sets out the rules trustees must follow. As of October 2026, this law applies to trustees managing trusts in Naperville and throughout Illinois. The trust document itself will also be important. The grantor can provide a number of rules that must be followed. Other rules are mandatory and will apply no matter what the trust says.

What Are a Trustee’s Core Legal Duties?

A trustee is a fiduciary who is legally required to act in another person’s best interest rather than their own. Under the Illinois Trust Code, a trustee’s main duties include:

• The duty of loyalty, which means managing the trust only for the beneficiaries’ benefit and avoiding conflicts of interest, such as buying trust property for themselves
• The duty of impartiality, which requires treating beneficiaries fairly and not favoring one over another unless the trust says to
• The duty of prudent administration, which means acting with reasonable care and skill
• The duty to keep trust property separate from the trustee’s own assets and keep accurate records
• The duty to invest wisely under the Illinois Prudent Investor Rule, which requires spreading out investments and considering the trust’s goals and the beneficiaries’ needs
• The duty to keep beneficiaries reasonably informed

What Should a Successor Trustee Do First?

The first few months after a trustee assumes control over a trust will set the tone for the entire administration of the trust. Taking organized steps early can prevent mistakes and misunderstandings later.

Review the Trust and Gather Documents

Start by reading the trust document carefully, along with any amendments. Get several certified copies of the person’s death certificate or other documents detailing why the grantor can no longer manage the trust. A certification of trust may need to be prepared. This is a short document that proves the trustee’s authority to banks and other institutions without sharing the full trust.

Notify the Beneficiaries

A trustee is required to notify qualified beneficiaries in writing within 90 days after accepting the role or after the trust becomes irrevocable. The notice must include the trustee’s name and contact information, and it must let beneficiaries know they can ask for a copy of the trust.

Locate and Secure the Assets

Make a list of everything the trust owns, such as real estate, bank and investment accounts, vehicles, and personal belongings. Change account titles into the trustee’s name, keep insurance in place on any property, and secure the grantor’s home. Get an employer identification number (EIN) from the IRS, since an irrevocable trust is treated as a separate taxpayer.

Pay Debts, Expenses, and Taxes

Use trust funds to pay valid debts, final bills, and administration costs. The trustee may need to file the grantor’s final income tax return and income tax returns for the trust. Larger estates may also owe Illinois estate tax, which can apply to estates worth more than $4 million.

Keep Beneficiaries Updated With Accountings

A trust accounting is a report that lists the trust’s assets, the money it received, and the money it paid out. Trustees generally must provide accountings at least once a year and when the trust ends. Clear, regular reports are one of the best ways to build trust with beneficiaries.

Distribute the Property

Once debts and taxes are handled, distribute the assets as the trust directs. Some trusts end after assets are distributed, while others may continue for years, such as a trust that pays for a grandchild’s education.

What Disputes Can Arise During Trust Administration?

Even well-run trusts can lead to conflict, especially when family members have different expectations. Common disputes may involve beneficiaries who believe a trustee is moving too slowly, disagreements over selling a family home, claims that a trustee is favoring certain relatives, objections to trustee fees, and challenges to the trust itself based on claims that a grantor lacked capacity to understand the decisions made when creating a trust or was pressured into changing the terms of a trust against their wishes.

Because parts of Naperville are in DuPage County and Will County, trust disputes involving local families may be handled in the Circuit Court of DuPage County in Wheaton or the Circuit Court of Will County in Joliet. A court can order a trustee to provide an accounting, pay back losses, or even be removed.

How Can a Trustee Protect Themselves and the Trust?

Most problems with trust administration are related to poor communication or sloppy recordkeeping, rather than bad intentions by trustees. A trustee can lower their risk by taking a few practical steps.

A trustee should never mix a trust‘s assets with their own. Open a separate trust bank account and run every payment through it. Save receipts and write down the reasons for important decisions. Communicate often and in writing, and respond to beneficiaries’ questions promptly.

Before selling major assets, consider getting a professional appraisal so no one can claim assets were sold too cheaply. If a trustee plans to take a fee, make sure it is reasonable. Be very careful with any transaction that benefits a trustee personally, even if it seems fair.

It is important to receive legal guidance early. A lawyer can help a trust meet deadlines, interpret unclear language in the trust, and respond to beneficiary concerns before they turn into lawsuits.
