## Definition

A successor trustee is the person or institution that takes over management and distribution of a trust when the original trustee dies, resigns, or becomes incapacitated. They have a fiduciary duty to administer the trust according to its terms and to act in the best interests of the beneficiaries.

## Key takeaways

- Successor trustees step in only when the prior trustee can no longer serve.
- They have fiduciary duties of loyalty, prudence, and impartiality.
- Choose someone with judgment, not just availability — family member, professional, or corporate trustee.
- Always name at least one backup successor trustee.

## How Olomon thinks about this

_The following section is Olomon's first-party perspective, informed by our work building a financial system of record. It is intentionally separated from the neutral definitional content above._

Olomon equips successor trustees with what they actually need on day one: a current view of the trust's assets, debts, and documents; the contact information for the legal, tax, and investment professionals already in place; and an audit trail of recent activity. That dramatically shortens the on-ramp and reduces the chance of expensive mistakes.

## In-depth definition

Naming a successor trustee is one of the most consequential decisions in setting up a trust. The successor steps into a role with broad legal authority and significant administrative work — inventorying assets, valuing them, paying [debts](https://olomon.com/financial-glossary/liabilities) and taxes, communicating with beneficiaries, and executing distributions consistent with the trust's terms.

## Frequently asked questions

### Should I name a corporate trustee?

Corporate trustees (bank trust departments, trust companies) bring continuity, professional administration, and impartiality — valuable when family dynamics are complex or the trust is long-lived. They charge fees, so weigh cost against value.
