The Five Legal Documents Every Family Needs, in Plain Language

Names vary by country and province, but the functions of these documents are universal, and all of them share one unforgiving rule: they can only be created while the person still has the mental capacity to understand them. Early is everything. If dementia is anywhere in the picture, do these the month you start wondering, not the month after diagnosis.

1. A will. Who gets what, and who is in charge of making it happen (the executor). Dying without one hands the decisions to a government formula.
2. A financial power of attorney (continuing or enduring, in Canadian terms). Names who can manage money and property if your parent cannot, temporarily or permanently. Without one, family must apply to a court or public authority to take over, a process that is slow, public, and expensive, arriving precisely at the worst moment.
3. A power of attorney or directive for personal and health care. Names who decides about care, housing, and treatment when your parent cannot, and can carry written wishes.
4. Written wishes about medical care (advance care plan, living will, the name varies). What matters to your parent at the end of life, what they would accept and refuse. The document matters; the conversation around it matters more, because the named decision-maker will one day need to hear your parent's voice in their memory.
5. The personal inventory. Not a legal document, but the map that makes all the legal documents usable: where everything is, who to call, how things are paid. The fill-in version is Section 2 of our free Family Caregiver's Complete Handbook.

Ontario has two powers of attorney: a Continuing Power of Attorney for Property (finances) and a Power of Attorney for Personal Care (health and living decisions), governed by the Substitute Decisions Act. The Ontario government publishes a free POA kit (ontario.ca, search "power of attorney kit"), though for anything beyond a simple situation, an hour with a lawyer who does elder law is money well spent.

If no Power of Attorney for Personal Care exists and a health decision must be made, Ontario's Health Care Consent Act automatically ranks substitute decision-makers: spouse or partner, then children or parents, then siblings, then other relatives, with the Public Guardian and Trustee as the last resort. Disagreements go to the Consent and Capacity Board. Knowing this hierarchy exists prevents both panic and family warfare, but a named attorney of your parent's own choosing beats the default list every time.

After capacity is lost, the only route to managing a parent's property is a guardianship application through the courts or the Office of the Public Guardian and Trustee: slow, expensive, and invasive. This is the outcome the documents exist to prevent.

1. Kits and online services are fine for simple situations. Blended families, business ownership, property in more than one place, or family conflict are worth a real lawyer, and one focused hour is cheaper than the mess.
2. Tell the named people they are named, and tell them where the documents are. A power of attorney nobody can find does not exist.
3. Revisit after any major life event: a death, a move, a diagnosis, a falling-out.

If capacity is already in question, do not panic and do not improvise. Every jurisdiction has a legal pathway for substitute decision-making, health systems have default decision-maker hierarchies for medical consent, and an elder law lawyer or hospital social worker can tell you exactly where you stand. Later than ideal is still workable. It is just slower, and it is why this page nags everyone else to go early.

If memory changes are what brought you here, the Dementia Concerns guide covers the whole path, including the Ontario-specific steps that are time-sensitive.
