Probate Litigation Is Becoming a Growth Sector: Why More Families Are Fighting Over Trusts, Homes, and Capacity

Disputes about how a deceased person’s property should be distributed are not a new or novel concept. However, courts are currently dealing with a higher volume of cases during probate. Families who seemed to have everything in order are now fighting over whether a parent understood what they were signing, whether a sibling exercised too much influence, or whether the language of a trust that was written years ago actually means what one side claims it means.

The reasons for these disputes are not difficult to trace. People are living longer, accumulating more assets, and often delaying formal estate planning until cognitive decline is already underway. Adult children who might once have deferred to a parent's wishes are more likely today to hire an attorney and challenge an outcome they believe is unfair.

Are Probate Cases on the Rise in the United States?

According to CourtTrax data from 2026, probate case filings have increased meaningfully across the United States in recent years, a trend that legal observers widely attribute to the largest intergenerational wealth transfer in American history. Baby Boomers hold an estimated $68 trillion in assets, and as that wealth moves to the next generation, disputes over how it should be distributed are multiplying.

Rising asset values, more complex ownership structures, blended families with competing interests, and longer periods of elder caregiving have all contributed to a probate environment that is more contested than it was a generation ago. In the absence of clear, updated estate plans, families often have to deal with prolonged probate cases and costly litigation.

What Does “Capacity” Mean in Probate, and Why Is it So Often Contested?

Testamentary capacity refers to the legal standard a person must meet to execute a will or trust. In most states, this means the person must understand the nature of the document they are signing, the extent of their property, who their natural heirs are, and how the document distributes their estate. The bar is not particularly high, but it is meaningful.

Capacity is contested so frequently because it is rarely documented at the moment it matters most. A person with early-stage dementia may have good days and bad days. An estate planning attorney who meets with a client for an hour cannot always detect cognitive impairments that their family members may see every day.

Medical records often describe symptoms in clinical language that does not translate cleanly into legal conclusions. Because the person whose capacity is in question is no longer alive to speak for themselves, courts may be forced to reconstruct their mental state from fragmentary evidence.

Allegations of Undue Influence in Probate Court

Undue influence claims arise when someone argues that a third party pressured or manipulated a person who created an estate plan into making decisions they would not have made freely. These claims are common in cases involving:

• A caregiver, romantic partner, or new spouse who was present during the estate planning process and benefited significantly from the final documents
• A child who provided primary care for an aging parent and received a disproportionate share of the estate compared to their siblings
• A family member who isolated the deceased from other relatives in the months or years before their death
• Sudden changes to a will or trust shortly before a person’s death that reversed a long-standing distribution plan
• A situation where the person who drafted the estate planning documents also stood to benefit from them

Proving undue influence requires showing that the pressure was so substantial it overcame the person's free will. Courts may look at the relationships between the parties, the opportunity to exert influence, the vulnerability of the person who made the plan, and whether the outcome makes sense given the person's known wishes and values.

Unclear Trust Language Can Lead to Conflict

Trusts are powerful instruments, but they are only as reliable as the language used to create them. When a trust says that assets should be distributed for a beneficiary's "health, education, maintenance, and support," that phrase may seem self-explanatory. In practice, trustees and beneficiaries regularly disagree about what a trust authorizes.

Disputes may also arise around the timing of distributions, the definition of who qualifies as a beneficiary, what happens when a named beneficiary dies before the trust’s assets have been distributed, and how a trustee's discretion is supposed to be exercised. Some of these conflicts may stem from genuinely ambiguous language. Others may occur because of an estate plan that was never updated to account for changed circumstances, new family members, or assets that were acquired after the trust was created.

When Estate Executors Clash With Beneficiaries

An executor, sometimes called a personal representative, has a legal duty to administer an estate according to the will and the applicable laws. They are required to protect the best interests of the beneficiaries rather than making decisions based on the executor's own interests or preferences. When an executor fails to handle an estate’s assets correctly, beneficiaries may have grounds to challenge the administration of the estate.

Common sources of conflict include delays in distributing assets, failure to properly inventory or value property, self-dealing by an executor who is also a beneficiary, refusal to provide accountings, and decisions about selling or managing estate assets that other beneficiaries disagree with.

When these conflicts cannot be resolved informally, the matter may end up in court. Beneficiaries who believe an executor is not fulfilling their responsibilities do not have to wait and hope the situation improves. The outcome depends on the nature of the alleged misconduct, the harm caused to the estate, and whether the beneficiaries can produce records showing that the executor failed to meet their legal obligations.
