There comes a moment in some lives when the voice of a person—once strong, deliberate, sure—grows faint. Not because they are unwilling to speak, but because they can no longer find the words. The illness takes hold. The mind becomes fog. Consciousness fades. And yet, the choices must still be made.
In this fragile place, substitute decision-making becomes more than a legal mechanism. It becomes an act of profound love, courage, and moral weight.
It is no small thing to speak for someone who can no longer speak for themselves.
Too often, we imagine autonomy as a solitary pillar—an individual’s right to choose their path. But real autonomy, the kind that endures through illness and incapacity, is communal. It is woven through the relationships we nurture, the conversations we dare to have, and the trust we extend to others to carry our wishes when we cannot.
To be a substitute decision-maker is not to choose what you would do, or what seems easiest in the moment. It is to become, as faithfully as possible, the voice of another soul. It is to step into their shoes and remember: How did they see the world? What gave them joy? What did they fear? What did they hope for, even in the face of death?
And it is this remembering—sometimes painful, always humbling—that allows decisions to be made with integrity.
There may be paperwork—advanced directives, power of attorney documents, written notes from years ago. But often, the most powerful guidance is found not in files but in memories. In the way someone flinched at the idea of tubes and machines. In the way they lit up when talking about home. In a conversation over tea when they once whispered, “If I can’t read, laugh, or recognize my children—I don’t want to be kept alive just to breathe.”
To be entrusted with that memory is a sacred burden. It is a kind of guardianship of the soul’s intentions.
And it is not easy.
Because sometimes, the choices are brutal. Do we withdraw life support? Do we attempt another surgery? Do we keep pushing, even when the body has already started to say goodbye?
There are no perfect answers. Only love, and the quiet courage to do what feels most aligned with who this person was—not just medically, but emotionally, spiritually, fully.
Clinicians play a role here, too. The best of them do not pressure or presume. They create space. They offer information without overwhelm. They ask gently, “What would she want?” and they help the substitute decision-maker navigate not just facts, but feelings—the guilt, the fear, the impossible ache of holding another’s life in your hands.
Let us not forget that substitute decision-making doesn’t only happen in sterile ICUs or during dramatic moments. Sometimes it’s about smaller but no less meaningful choices: whether to start a feeding tube, whether to enroll in hospice, whether to continue with aggressive treatments or focus on peace.
And sometimes, it is not one decision, but a hundred small ones—each a brushstroke on the canvas of someone’s final days.
For those who find themselves in this role: take heart. You do not have to be perfect. You only have to be present. You only have to try, with honesty and humility, to honor the voice that now rests in silence. And in doing so, you offer a final gift—an affirmation that even in incapacity, this person still matters, their values still hold, and their story still guides.
To stand in for another human being at the edge of life is to become a mirror, a vessel, a compass.
It is a quiet heroism, rarely acknowledged.
But it is one of the most human acts we will ever be asked to perform.
So speak with love. Decide with care. And know that in this tender space, you are not alone.
You are the echo of someone’s voice.
And that voice still matters.
