A large portion of Americans still do not have an estate plan. A 2025 survey of 10,000 U.S. adults by Trust & Will found that 55% had no estate plan, 31% had a basic will, and 11% had a trust.
A 2025 Caring.com and YouGov survey of more than 2,500 American adults found that only 24% reported having a will, while 13% reported having a living trust.
Sometimes, a trustee must distribute the trust, but the trust document is unclear about who gets what, and there is no agreement. Trust assets might be lost or given away in other ways. A family member may claim that certain assets were given to them before death. Beneficiary changes also often trigger issues. Beneficiaries may question how a trustee handled distributions or claim the trustor lacked capacity or was unduly influenced. Any of these reasons can lead to trust litigation.
An estate plan serves as an effective mechanism for providing some peace of mind by clearly communicating one’s wishes while simultaneously streamlining estate administration. A provision that conflicts with state law may not be enforceable. On account of these potential risks, many people who hold intricate asset types and complicated wishes engage the services of a trust-based estate planning lawyer.
Good estate planning often pays off after the fact. The process can feel stressful, but a little time spent on it can spare family members a great deal of stress when the unforeseen happens.
Why Trusts Fight Off Challenges Better Than Wills, When Done Right
Timing is the main reason trusts hold up better than wills. Wills take effect upon death. Living trusts differ, because they are established and funded during the life of the trustor. These trusts are often created years prior to death, and the trustor may serve as trustee for the trust.
A challenger may still argue coercion or confusion, but those claims are tough to sell when the trustor has spent years treating the trust as their own.
Since the house, accounts, and other property are titled in the trust’s name, they pass to beneficiaries without undergoing probate.
Where Trust Disputes Actually Come From
That advantage has limits. Trusts still get challenged. For example, a trust can be contested for lack of mental capacity, especially if the trustor made changes close to their death or while seriously ill.
Undue influence allegations often emerge from situations where a spouse, an adult child, or an adult caregiver appears to have improperly pressured the trustor. Disputes over trust language, along with claims of trustee mismanagement or breach of duty, also drive trust conflicts.
When these conflicts can’t be settled privately, they end up in court, and that process is rarely quick. California is a useful example. A detailed walk-through of how California trust litigation actually proceeds, from pre-litigation mediation through discovery and trial, shows just how long and costly this process can become once a dispute moves past the point where careful drafting could have headed it off.
The Planning Choices That Actually Prevent Disputes
One cannot overstate the importance of clarity and precision in drafting trust terms. Ambiguity opens a trust to future litigation. The consequences of weak drafting may not manifest until many years later.
A trust that is drafted but never funded can leave assets outside it, and those may end up in probate, the very process the trust was meant to avoid. Proactively updating a trust, rather than rushing to amend it during a health emergency, makes a capacity challenge less likely.
Documentation Protects a Plan Long After It’s Signed
The trustor’s own documents made at the time can be used to address any future conflicts.
A letter explaining why one child receives less, attorney notes confirming the trustor’s capacity, or a doctor’s evaluation done when the trust was signed can all speak for the trustor once they no longer can.
Open communication among family members can also defuse the emotions that turn a disagreement into a lawsuit.
The Practical Reality
Most trust disputes don’t come from a legally defective document. They come from uncertainty, incomplete funding, poor planning, or family members who never understood the reasoning behind decisions until it was too late to ask.
A well-drafted trust closes off many of the openings that lead to disputes. It works best when it is funded from the start and explained to everyone involved while the trustor can still do so.
