One of the more difficult family dynamics I see in estate planning arises when one child has taken on most of the responsibility for an aging parent.

 

That child may live nearby, handle medical appointments and emergencies, help with finances, run errands, and spend countless hours providing care and support. Over time, they may understandably become frustrated or resentful that their siblings have not done more. Sometimes that resentment develops into a sense of entitlement: I am the one who has been here. I am the one doing all the work. Why should my sibling receive the same inheritance I do?

 

That mindset can create risks of its own. A child who feels entitled to be compensated may become less careful about financial boundaries—using a parent's funds, accepting substantial gifts, changing how accounts are handled, or encouraging estate planning decisions that benefit them—because, in their mind, they have earned it. That does not necessarily mean the child is intentionally exploiting the parent. But resentment and a sense that I deserve this can make conduct seem justified to the person engaging in it even when other family members may see it very differently.

 

Meanwhile, there is often another side to the story.

 

A sibling who lives farther away—or simply has had a different relationship with the parent—may feel increasingly shut out. The caregiving child may naturally become the gatekeeper of information, medical appointments, finances, and access to the parent simply because that child is the one who is there. But to the sibling on the outside, that can feel like intentional exclusion or control.

 

And when the distant child does become more involved as the parent's health declines, the two siblings may interpret the exact same behavior very differently. The caregiving child may think, You're only showing up now because there is an inheritance coming. The other child may be confronting the fact that they are about to lose their mom or dad and experiencing grief, regret, or sadness about a relationship that was not as close as they wished it had been. The less-involved child may also become suspicious: Why won't anyone tell me what's going on? Why is my sibling controlling Mom's finances? Why did Mom suddenly change her estate plan? Sometimes there is a legitimate reason for concern. Sometimes there isn't. But once distrust takes hold, even ordinary decisions can begin to look suspicious.

 

Then add inheritance to the equation.

 

If the caregiving child receives more, the other child may experience that not simply as a financial decision, but as a final message from the parent: My sibling mattered more. My sibling was loved more. I wasn't enough. That may be nowhere close to what the parent intended.

 

There is no universal rule that children should inherit equally—or that a child who provides substantial care should receive more. Most parents I work with choose equal distributions among their children, even when their children have contributed very differently to their care. Others have thoughtful reasons for making different choices.

 

The key is to recognize these dynamics before resentment, entitlement, exclusion, and suspicion have a chance to take over.

 

For parents navigating this situation, there are some practical steps that can help:

 

• Decide whether caregiving should be compensated. If one child is providing substantial ongoing care, address compensation directly rather than allowing an unspoken expectation to develop that the child will eventually “make it up” from the parent's assets or inheritance. If the parent wants to pay the child, put an appropriate arrangement in place and document it.
• Keep finances transparent and well documented. If a child is managing a parent's money, keep records of expenditures, reimbursements, gifts, and transfers. Good records protect the parent and the caregiving child.
• Be careful about informal financial arrangements. Adding a child to an account, giving a child a debit card, transferring money, or allowing a child to reimburse themselves without documentation may seem harmless within a family. Later, those same transactions can become the centerpiece of an elder-abuse or undue-influence claim.
• Pay attention when one child controls virtually all access and information. Sometimes that happens simply because one child is doing the work. But whenever possible, parents should decide for themselves who receives information and who should be involved, rather than allowing those decisions to happen by default.
• Think carefully before making significant estate-plan changes that favor a caregiver. An unequal plan may accurately reflect the parent's wishes. But when the person benefiting from the change is also the person providing transportation, managing finances, arranging appointments, or controlling access to the parent, additional care should be taken to ensure that the parent's wishes are independent and well documented.
• Choose fiduciaries with family dynamics in mind. The child who has handled everything may seem like the natural trustee or executor. Sometimes that is absolutely the right choice. But if distrust already exists, placing that child in complete control after the parent's death can intensify the conflict. A neutral fiduciary may sometimes be worth considering.
• Consider whether some communication would help. Parents do not have to disclose their estate plans to their children. But if the plan contains a significant surprise—particularly an unequal distribution—some explanation of the parent's reasoning may prevent the children from creating their own explanation after the parent is gone.

 

Perhaps the most useful question isn't simply “What distribution seems fair?”

 

It is also: “What family dynamics are developing now, and what can I do to prevent them from becoming a source of conflict later?"

 

These issues are much easier to address while a parent is alive, capable, and able to make and explain their own decisions. Clear expectations about caregiving and compensation, good financial records, appropriate boundaries, thoughtful selection of fiduciaries, and careful documentation of estate planning decisions can all help reduce the opportunity for misunderstanding—or misconduct—later.

 

No estate plan can eliminate complicated family relationships. But good planning can avoid adding unnecessary fuel to them. That matters because after a parent dies, siblings aren't just dividing an estate. They're grieving a parent, often carrying years of unresolved feelings with them, and trying to make sense of the decisions that parent left behind.
