When creating a revocable living trust, one of the most crucial decisions you'll make is choosing who will manage your trust on your behalf. This decision carries profound implications for your legacy, your beneficiaries' financial well-being and your family's harmony. While naming multiple trustees – known as co-trustees – might seem like a prudent way to ensure proper oversight and fair treatment of beneficiaries, this approach often introduces complexities that can threaten the very goals you're trying to achieve.
The Thompson family learned this lesson the hard way. Mr. and Mrs. Thompson had built a comfortable estate through decades of careful saving and investment in their family business and rental properties. Wanting to treat their three children equally and believing that shared responsibility would prevent any potential mismanagement, they named all three siblings as co-trustees of their $2.4 million living trust.
What seemed like a thoughtful decision soon unraveled after Mr. Thompson’s passing and his widow’s subsequent diagnosis of dementia. Their son, a cautious financial advisor, wanted to maintain the trust's conservative investment strategy. Their daughter, an entrepreneur, pushed for diversifying into higher-yield investments. Their youngest son, who lived three states away, struggled to participate in time-sensitive decisions about property maintenance and tenant issues. Their weekly conference calls about trust matters devolved into heated arguments about their parents' true intentions.
The situation reached a breaking point when an urgent decision about refinancing one of the rental properties was delayed for three months while the siblings debated the terms. The bank required all three co-trustees to sign off on the refinancing, but they couldn't reach consensus. Meanwhile, interest rates rose, costing the trust thousands in potential savings. Family gatherings became tense affairs, with siblings barely speaking to each other. Eventually, they needed to hire a mediator at $400 per hour to help resolve their differences, depleting the very trust assets they were trying to protect.
The challenge lies in the fundamental nature of trustee duties. A trustee must make timely decisions about investments, distributions and asset management while following strict fiduciary obligations. When these responsibilities are shared among co-trustees, even routine matters can become complicated by competing perspectives, different financial philosophies and varying levels of availability or expertise. Financial institutions often compound these difficulties by requiring unanimous consent from all co-trustees before executing transactions, potentially freezing trust assets when quick action is needed.
Modern trust administration has evolved to become increasingly complex, requiring knowledge of tax laws, investment principles and fiduciary responsibilities. While sharing these duties might appear to distribute the burden, it often creates a scenario where decision-making becomes unnecessarily cumbersome, potentially jeopardizing the trust's effectiveness and your beneficiaries' interests. The Thompsons' experience illustrates how co-trusteeship can transform routine administrative tasks into contentious family disputes that threaten both the trust's effectiveness and family relationships.

What motivates grantors to name multiple trustees?
Grantors typically consider naming co-trustees for several well-intentioned reasons. Many parents want to treat their children equally and avoid showing favoritism. Others believe that having multiple trustees provides better oversight and reduces the risk of mismanagement or abuse. Some grantors think that sharing responsibilities will make the trustee role less burdensome for any single individual.
These motivations reflect genuine concerns about trust administration and family dynamics. However, the practical challenges of co-trusteeship often outweigh these perceived benefits, potentially creating more problems than they solve.
How do co-trustees make decisions about trust administration?

Co-trustees must reach unanimous agreement on all trust decisions unless the trust document specifies otherwise. This requirement creates significant operational challenges in practice.
Time-sensitive matters highlight these difficulties. Investment opportunities require all co-trustees to agree on merits, timing and amounts – often causing missed opportunities. Even routine tasks like property maintenance and beneficiary distributions face delays while awaiting multiple approvals.
This unanimity requirement often leads to "administrative paralysis" when co-trustees have different views on trust management. One trustee might prefer conservative investments while another pushes for aggressive growth. Such philosophical differences can deadlock both major decisions and daily operations.
Trust interpretation further complicates matters. Co-trustees frequently disagree about grantor intentions regarding distributions, beneficiary treatment and investment parameters. The Thompson family exemplifies this: When their rental property needed a new roof, three trustees debated contractor selection for months. During these delays, water damage increased repair costs substantially.
While co-trusteeship aims to provide better oversight, the consensus requirement often leads to costly delays and missed opportunities. Geographic separation and varying availability compound these challenges. Simple decisions can require extensive discussion and documentation to satisfy all trustees' concerns.
These decision-making hurdles demonstrate why grantors must carefully weigh shared responsibility against the practical implications of requiring unanimous consent for trust administration.
What problems do financial institutions face with co-trustees?
Financial institutions often struggle to work with co-trustees, creating additional complications for trust administration. Banks, investment firms and other financial organizations typically require documentation proving all co-trustees agree before executing any transactions. This requirement can result in:
- Delayed account access and frozen assets.
- Additional paperwork and documentation requirements.
- Increased administrative costs.
- Potential liability concerns for financial institutions.
- Complex verification processes for routine transactions.
How does co-trusteeship affect trust administration costs?

Managing a trust with multiple trustees often leads to increased expenses that can diminish trust assets. These additional costs may include:
- Higher legal fees for resolving disputes.
- Increased administrative expenses for documentation.
- Multiple trustee compensation arrangements.
- Extra accounting and reporting requirements.
- Professional mediation services when conflicts arise.
What are alternatives to naming co-trustees?
Appointing a single trustee with clear succession provisions can provide streamlined decision-making while ensuring continuity of trust administration. This approach works particularly well when the chosen trustee has strong financial acumen and a thorough understanding of the grantor's wishes.
Professional trustees and trust companies represent another effective solution. These entities can bring expertise, objectivity and institutional stability to trust administration. Their services involve fees, but these costs may prove lower than expenses incurred through co-trustee conflicts and delays.
A trust protector role offers another layer of oversight without compromising efficient administration. This independent third party can monitor the trustee's actions, replace trustees if necessary, and resolve disputes. Trust protectors provide the checks and balances grantors seek from co-trustees without hindering day-to-day operations.
Specific provisions for beneficiary monitoring can also enhance trust oversight. These might include regular accounting requirements, professional audits or beneficiary consent requirements for major decisions. Such provisions protect beneficiary interests while maintaining clear, singular trustee authority.
How can estate planning professionals help with trustee selection?

Working with experienced estate planning professionals can help identify the most effective trustee arrangement for your situation. These advisors can:
- Evaluate potential trustees' qualifications.
- Suggest appropriate oversight mechanisms.
- Draft clear trustee guidelines.
- Recommend professional trustee services.
- Design effective succession provisions.
Selecting the right trustee arrangement is crucial for ensuring your trust operates as intended. While naming co-trustees might seem like a prudent choice, the potential complications often outweigh the perceived benefits. Consider working with qualified estate planning professionals to develop a more effective trustee strategy that provides proper oversight while avoiding the pitfalls of co-trusteeship.
Conclusion
Estate planning requires careful consideration of how your trust will be managed after you're no longer able to do so. While naming co-trustees may seem like an equitable solution, the Thompson family's experience demonstrates how this arrangement can lead to administrative gridlock, family conflict and diminished trust assets. Instead, consider alternatives like appointing a single trustee with clear succession provisions, engaging a professional trustee or establishing a trust protector role. Work with qualified estate planning professionals to create a trustee structure that provides effective oversight while maintaining efficient trust administration. Your choice of trustee arrangement today will significantly impact your legacy's protection and your beneficiaries' future well-being.
