How do siblings agree on home care decisions for an aging parent?

Sibling disagreement about an aging parent’s care is usually not about care — it is about information asymmetry. The sibling who lives closest sees the daily reality; the sibling who visits quarterly sees the parent on their best behavior; the sibling who calls weekly hears what the parent chooses to share. Each has a partial picture and each defends it.

The unlock is a shared document set that gives every sibling the same information at the same time. Four items usually cover it: (1) a current medical picture — diagnoses, medications, most recent primary-care and specialist notes; (2) a written care plan from a home care intake — what tasks need help, at what times, at what safety risk level; (3) a monthly cost estimate showing hours needed × rate; (4) explicit family roles — primary decision-maker (usually with POA), financial lead, local point of contact for the caregiver, and the person who talks to the parent about the decision.

A Southeast Michigan home care intake typically produces items 2 and 3 in a one-hour meeting, and helps organize items 1 and 4. Having all four in writing turns the sibling conversation from "I think Mom needs help" into "Here is the plan and the cost — who is doing what?"

One structural note: the sibling who is the legal decision-maker (via power of attorney or family agreement) has final say. When siblings dispute over decisions the POA is legally authorized to make, the conversation shifts from consensus to consultation. Getting the POA and the medical directive in place before the crisis is the single highest-leverage step siblings can take.
