You hired an attorney, signed the documents, and walked out of the office believing your family was protected for decades ahead. Bank of America Private Bank reviewed the trust drafting process and found that most families overlook five critical questions that could quietly unravel the entire plan.
The problems tend to emerge years later when you are no longer around to clarify your intentions for your family and their inheritance. A vague definition, a missing succession clause, or an overly rigid distribution schedule can transform a well-meaning document into a prolonged courtroom battle.
Trust ownership among Americans rose from 11% to 14% between 2025 and 2026, the Trust & Will 2026 Estate Planning Report found. More families are choosing trusts over standalone wills, but the shift also means more people are exposed to drafting errors they may not discover until a crisis.
One vague word in your trust could disinherit someone you love
The most dangerous flaw in any trust is ambiguity, and it often hides inside a single word that feels perfectly clear on the day you sign. Your trust might state that all your “children” should benefit equally from the assets you leave behind.
The legal definition of “children” varies from state to state, and it may not include stepchildren or children born through assisted reproduction. “If you want a stepchild to benefit, that’s something you should spell out explicitly,” Scott Marantz, National Trust Executive at Merrill, Bank of America, said.
Courts interpret trust language strictly, and a judge will not guess what you meant when you used a broad term like “descendants.” Your biological children could challenge a stepchild’s right to distributions if the trust does not specifically name that person as a beneficiary.
How undefined assets create disputes that drain your estate
Cash and securities are relatively simple to divide, but a vacation home, a jewelry collection, or shares in a family business carry emotional weight alongside financial value. “If you want something to go to a specific family member but don’t spell it out in the trust, that asset may be sold and the money distributed among beneficiaries,” Marantz explained.
You can direct the trustee to make distributions based on specific needs by including language such as “health, education, maintenance, and support.” Another option is to specify whether beneficiaries should use their own resources before turning to the trust for additional support.
Unclear asset instructions can spark disputes, force sales, and quietly erode the value you meant to pass on.
A simple letter could prevent years of family conflict over your trust
“Trust documents by their nature have a very formal construction to ensure that they can be properly administered and upheld,” Erica Webber, Senior Trust Officer for Bank of America Private Bank, said. “But they don’t always tell the story of ‘why.’”
A “letter of wishes” supplements your trust by explaining the personal reasoning behind specific decisions you made for your beneficiaries. This document is not legally binding, but your trustee and heirs can reference it to understand your intentions when the formal trust language feels rigid.
Ambiguous trust language is one of the most common triggers for litigation between beneficiaries and trustees,as noted by probate attorneys at Keystone Law Group. Courts can intervene to interpret vague provisions, but the process is expensive and time-consuming for everyone involved.
Overly rigid trust instructions can backfire on your beneficiaries decades later
Your instinct might be to spell out every detail of how and when beneficiaries receive their money, but that approach can create problems down the road. “You can’t know for sure what circumstances your children or grandchildren may face 10, 20, or 30 years from now,” Webber warned.
Divorce, disability, and financial hardship are impossible to predict at the time you draft the trust. A trust that requires payouts at fixed intervals poses a specific risk to beneficiaries going through personal crises, such as divorce proceedings.
Those assets could end up in the hands of a former spouse or creditors if the distribution date lands at the wrong moment. Dollar amounts written into the document years in advance also fail to account for inflation over the life of the trust.

The federal estate and gift tax exemption increased to $15 million per individual on January 1, 2026, under the One Big Beautiful Bill Act. Married couples can now shield up to $30 million in combined assets, and many existing trusts were built around exemption levels that were a fraction of today’s amount. Your trust’s distribution terms may no longer align with the current tax landscape.
“Flexibility is key,” Webber said. “General guidelines as opposed to mandates can help trustees stay true to your intentions.” You should give your trustee enough discretion to respond to changing circumstances while keeping the guardrails tight enough to reflect your core values and priorities.
An equalization provision protects your family from unequal distribution disputes
Your beneficiaries will likely have different financial needs over the life of the trust, and some may request larger distributions than others. That imbalance breeds resentment, especially if one sibling feels shortchanged, Jennifer Galvagna, Head of Trust, Estates and Tax for Bank of America, explained.
“A revocable trust is great at keeping assets out of probate and provides ample flexibility for defining the succession of decision-making,” said Andrew Tanner, Managing Director, Specialty Asset Investment Consultant at Bank of America Private Bank.
“The provision might be as simple as: We want the trustee to consider gifts made during our lifetime and through this trust, so that the beneficiaries come out equal,” Galvagna said. When the trust expires, and assets are divided, earlier distributions to a beneficiary are subtracted from that person’s final share.
Your trust needs a backup plan for when your trustee can no longer serve
Your trustee operates as a fiduciary who is legally required to serve the best interests of the trust and its beneficiaries, and that person may not be available forever. “A succession plan could either mention successor trustees by name or describe an orderly process for finding replacements,” Marantz recommended.
Options for trustee succession planning
- Name specific successor trustees in the document to avoid ambiguity about who assumes the fiduciary role.
- Appoint a professional, such as a CPA, attorney, or corporate trustee, to serve as trustee or co-trustee alongside a family member.
- Designate a trust protector with the authority to remove and replace an underperforming trustee when fiduciary obligations are not being met.
“If you design your trust to be multigenerational, at some point a corporate fiduciary will likely come into play because it’s impossible to anticipate the future needs of your family,” Webber said. Building that language into the trust from the start prevents a leadership gap that could leave your assets vulnerable.
Your trust should tell your family how to care for you if you cannot speak for yourself
Most people draft a trust focused on what happens after they die, but few address the possibility that they may become incapacitated first. “People may overlook that middle piece: ‘What happens if I’m alive but can’t make decisions on my own?’” Galvagna said.
You should specify whether you want to remain at home with full-time care, whether you are open to a nursing facility, and how much of the trust should fund your care versus what is preserved for your beneficiaries.
“Be sure your trust language aligns with other documents, such as living wills and durable powers of attorney,” Galvagna advised. If you currently support children, aging parents, or charities from your personal accounts, you should also add language authorizing the trustee to continue those payments if you can no longer write the checks yourself.
5 steps you should take with your trust attorney this year
Roughly 56% of American adults still have no estate planning documents, and 42% would not know what to do if a family member died today, the Trust & Will 2026 report found. If you already have a trust, you are ahead of most households, but these drafting details determine whether your plan holds up.
- Step one: Review every defined term, including “children,” “heirs,” and “descendants,” to confirm the legal definitions match your personal intentions.
- Step two: Identify illiquid assets such as real estate and business interests, and add explicit instructions for how each should be distributed.
- Step three: Draft a “letter of wishes” that explains your reasoning behind key decisions so your trustee understands your true intentions.
- Step four: Verify that your trust includes a succession plan for your trustee and consider whether a corporate fiduciary should serve as a backup.
- Step five: Add incapacity provisions that specify your care preferences, align with your power of attorney, and authorize ongoing support for dependents.
Your trust is only as strong as the language inside it, and even irrevocable trusts can be modified to clarify your original intentions. You do not need to start from scratch; you need to ask the right questions and write the answers into the document.
