Everything a life leaves behind, in one place.

End-of-life planning is the work of writing down four things while you still can: what medical care you want, who decides for you, who gets what, and how the people you name will actually reach any of it. Everything else is detail. Most people can make a real start in an afternoon, and then add to it over years.

It is not one enormous document. It is a set of separate pieces, each of which stands on its own, which is why you can begin with whichever one has been bothering you and leave the rest for later.

What documents do you need for end-of-life planning?

Four documents cover most people, and two of them are medical rather than financial.

• A living will — your instructions for medical care if you cannot speak for yourself: resuscitation, ventilators, feeding tubes, pain relief. In most US states it forms part of a broader advance directive.
• A power of attorney — the person allowed to act for you. Most families need two: one for healthcare, one for money. If you are unsure which document does what, start with living will vs power of attorney, because confusing the two is the single most common mistake we see.
• A last will — who inherits what, and who administers it. That administrator is your executor, and the job is bigger than most people expect. Where an estate is complicated, it is worth knowing how a will differs from a trust before you choose.
• A record of your digital life — accounts, subscriptions, photos, and the platform settings that decide who may see them. A will does not control most of it, which is why your digital legacy needs handling separately.

If you would rather work from a list than a page of prose, the documents to fill out before you die checklist covers the same ground in order, and where each document should live deals with the part everyone forgets.

What order should you do it in?

Start with the medical documents, because they are the ones that get used while you are still alive and they are the cheapest to put in place. A living will and a healthcare power of attorney can often be completed from free state forms in an afternoon.

Then do the will, then the digital and practical layer: where things are, who to call, which accounts exist. That last part is the one families beg for and almost never get. Naming the people who will carry it out is what turns a folder of documents into something that actually works when it is needed.

How much does end-of-life planning cost?

It ranges from nothing to several thousand. Many US states publish free advance directive forms, so the medical half can genuinely cost zero. An attorney-drafted will typically runs from several hundred dollars into the low thousands, more for a complex or contested estate. Between those two poles sit online services, Myend among them, at a fixed price.

Cost is rarely what stops people. In our own audience research the barrier that comes up most is not price but trust — whether the documents will be safe, and whether anyone will find them.

When should you start?

Any legal adult can do this, and the best moment is while nothing is wrong. Plans made under pressure are the ones with gaps in them. There is no age or diagnosis that qualifies you; the only requirement is being well enough to think clearly, which is precisely the thing you cannot count on later.

What happens if you don’t plan?

State law decides instead of you. For medical care, many states name a default decision-maker — usually a spouse, then adult children — so someone will be asked, though not necessarily the person you would have chosen, and not with any knowledge of what you wanted. For money and property, the gap is harder: without a power of attorney a court-appointed guardian or conservator may be needed, which takes months and costs real money. Without a will, the state’s intestacy rules distribute your estate.

None of that is catastrophic on paper. It is simply slower, more expensive, and decided by strangers, at the worst possible time for the people you love.
