Adult Child Caregivers Risk Sibling Legal Battles After Parent Death

Published: August 9, 2026, 9:30 pm

An adult child suddenly thrust into the role of caring for an aging parent faces a deeply stressful situation, but experts warn that the most difficult challenges often emerge only after the parent has passed away. During the final years of a parent's life, the caregiver often performs the heavy lifting of daily support, yet they frequently become the target of unprovoked criticisms, accusations of stealing from the ailing parent, and challenges regarding medical decisions from other family members. These critics are often siblings or relatives who were not interested in or participating in the day-to-day caregiving work. After the parent dies, these rumblings often escalate into formal lawsuits against the child who provided the care.

The American Bar Association has warned that the coming decade will see a "probate storm" of contested inheritance disputes as mortality rates for the baby boomer generation rise and their estates transition to beneficiaries. This trend suggests that many burned-out adult children will likely face the burden of expensive lawyers' fees while still grieving the loss of a parent, often at a time when their own finances are already stretched thin after years of caregiving. Carol Bradley Bursack, a certified dementia support group facilitator and author, notes that while there is occasionally a legitimate reason for family suspicion, more often than not, the relatives who avoided caregiving are simply not interested in an explanation for what they view as their lost inheritance. According to Bursack, these individuals often seek vengeance, which can result in litigation.

While it is estimated that the "Great Wealth Transfer" will move $124 trillion from the older baby boomer generation to younger heirs over the coming decades, experts warn that family conflicts could erode much of that wealth. Disputes that reach the level of litigation are notoriously costly. Legal fees, administrative costs, and court delays can consume assets that were originally intended for heirs or charities. Families may find themselves embroiled in probate court for months or even years, with wealth tied up and inaccessible to anyone. Unless the adult child caregiver is specifically named as an executor or trustee of the estate, they will likely have to pay their own legal fees to defend against accusations of theft or poor medical choices. Executors and trustees, by contrast, may be able to tap into estate funds to cover legal costs.

Larry Mandelker, a partner at Venable LLP, highlighted the harsh reality of the legal system, noting that one could be sued for almost anything, including "shooting JFK." He explained that being sued does not mean the caregiver will lose the case, but it does mean they are forced to fight and spend significant money to defend themselves. This financial strain, combined with the emotional trauma of family betrayal, can be overwhelming. Bursack shared that the stress of this situation, on top of years of sacrifice, can be too much for some. She recalled one caregiver who had brought her mother, who suffered from early-onset Alzheimer’s, into her own home for years, only to face such intense conflict that it led to a tragic outcome. These fractured relationships are increasingly common, as a 2024 Harris Poll of 1,068 U.S. adults showed that 35% of respondents were estranged from an immediate family member, such as a parent or sibling.

To protect themselves, experts strongly advise that individuals talk to a lawyer before taking on the primary caregiver role. Patrick Simasko, an elder law attorney and financial adviser at Simasko Law, recommends meeting with an elder law attorney to secure power of attorney and signed caregiver documents. He advises that before touching a parent's finances or medical decisions, one should ask a lawyer how to stay out of trouble. While planning is the best way to avoid problems, caregiving needs often emerge suddenly, making it difficult to prepare. Bursack acknowledges that in emergencies, such as when cognitive decline becomes suddenly evident, family members rarely think to keep every receipt or maintain detailed logs. Even with a well-documented paper trail, some family members will still push through with legal action, though the court will likely side with a well-documented caregiver. Bursack expressed hope that in-home care might one day become a covered Medicare benefit, which would be a significant step toward supporting those who, by some estimates, save the government more than a billion dollars each year by providing unpaid care for vulnerable elders.

Deepening financial woes add trauma, experts said.
