Durable Power of Attorney for Health Care (DPAHC) designations can shape sibling relationships in unexpected ways. When one child is appointed as the sole healthcare agent, other siblings may feel excluded, mistrusted or resentful. Research indicates that surviving adult children report higher-quality sibling relationships when the deceased parent designated someone other than a spouse or child as the DPAHC. This finding suggests that removing siblings from sole decision-making authority may reduce interpersonal conflict during emotionally charged end-of-life situations.
The structure and use of a DPAHC can further influence family dynamics, depending on how authority is assigned and exercised. Parents may appoint children jointly as co-agents or designate them in a specific order of authority. While these legal arrangements clarify who holds decision-making power, they do not guarantee family harmony. The manner in which authority is carried out is often more consequential than the formal designation itself.
To preserve positive sibling relationships, appointed agents, whether serving jointly or individually, should prioritize collaborative and transparent communication by openly discussing medical options, professional recommendations and the parent’s stated values and preferences with all siblings.
