Sibling Conflict Over Power of Attorney in Connecticut: How to Resolve Disputes Before Court

One sibling lives nearby and handles the day-to-day caregiving. Another sibling lives out of state but was named as power of attorney years ago, during a quiet Sunday visit when nobody else was around. Now the hands-on sibling wants authority to manage finances, the out-of-state sibling won't relinquish control, and both believe they know what's best for the parent. The parent, caught in the middle, may no longer have the capacity to resolve it.

Sibling disputes over power of attorney are one of the most common triggers for probate court involvement in Connecticut. They're also one of the most preventable — if the family addresses the underlying issues before positions harden.

Where the Conflict Usually Starts

The dispute rarely begins with the legal document itself. It starts with unequal caregiving burdens. One sibling provides daily physical care — driving to doctor's appointments, managing medications, handling meals — while another sibling holds the legal authority to manage finances. The caregiver feels exploited. The POA holder feels accused. Both feel unappreciated.

This pattern intensifies when money enters the picture. The caregiving sibling notices that bills aren't being paid on time, or that the parent's assets seem to be declining faster than expected. The POA-holding sibling suspects the caregiver is angling for financial control. Neither sibling has enough transparency into what the other is actually doing.

Connecticut's POA statute doesn't require the agent to report to other family members or provide financial accountings unless the document itself or a court order mandates it. This lack of built-in transparency is what allows suspicion to fester.

Options Before Court

Family meeting with an agenda. Not a venting session — a structured conversation about roles, responsibilities, and financial transparency. Agree in advance on what information the POA agent will share (account balances, major expenditures, care decisions) and how often. Put the agreement in writing, even if it's not legally binding.

Add a co-agent or monitor. If your parent still has capacity, they can amend the POA to add a second agent (co-agent) who must co-sign on transactions above a certain amount, or name a third party as a monitor who receives copies of financial statements. Connecticut's statutory forms allow for this kind of customization.

Mediation. Connecticut probate courts encourage mediation before contested hearings. A professional mediator familiar with eldercare disputes can help siblings reach agreements about care arrangements, financial management, and communication protocols. Mediation is faster and cheaper than litigation, and the agreements can be filed with the probate court for enforcement.

When Court Becomes Unavoidable

If the parent lacks capacity and the family can't agree, the probate court is the only institution with authority to resolve the dispute. Common scenarios that end up in court:

• One sibling alleges financial exploitation. If the POA agent is misusing the parent's funds, any interested party can file for conservatorship. The court can revoke the POA's practical effect by appointing a conservator whose authority supersedes the agent's.
• The parent executed the POA under undue influence. If one sibling believes the parent was coerced or manipulated into naming another sibling as agent, they can challenge the document's validity in probate court. This requires evidence — not just suspicion — that the principal was pressured.
• No one can agree on care decisions. When siblings disagree about where the parent should live, what medical treatment to pursue, or whether to spend down assets for Medicaid, the probate court can appoint a conservator with clear authority to make those decisions.

Contested conservatorship proceedings in Connecticut are expensive. Both sides typically hire attorneys ($300–$550 per hour), and the process can take months. The court also appoints an independent attorney for the parent, whose fees come from the parent's estate.

Preventing the Dispute in the First Place

The strongest protection against sibling conflict is a well-drafted POA executed while the parent can participate in the conversation. Specific steps that reduce future disputes:

• Name the agent openly. Don't let one sibling arrange the POA privately. Have the parent discuss their choice with all children.
• Include accountability provisions. Add language requiring the agent to provide quarterly financial summaries to all interested parties.
• Name a successor agent. If the primary agent can't or won't serve, a named successor prevents a vacuum that triggers a court fight.
• Separate financial and medical authority. Giving one sibling the financial POA and another the Health Care Representative appointment divides responsibility and gives each a defined role.
