Most people need six to eight documents to cover the full scope of end-of-life planning: a will, a living trust (optional but common), a financial power of attorney, a healthcare power of attorney, a living will, a letter of instruction, and, for those with serious illness, a medical order like a POLST form. Some of these are legally binding, others are guidance documents, and each serves a distinct purpose. Here’s what each one does and why it matters.
Your Will
A will specifies how your property, money, and other assets will be distributed and managed when you die. It’s also where you name a guardian for minor children. Without one, your state’s default inheritance laws decide who gets what, which may not match your wishes at all.
A will only takes effect after death, and it typically goes through probate, a court-supervised process that verifies the document and oversees distribution. That process can take months. If you want certain assets to transfer faster or stay out of public record, a living trust handles that (more below). But a will remains the foundation because it catches anything not covered by a trust, beneficiary designations, or joint ownership.
At least 15 states now accept electronic wills, including Arizona, Colorado, Florida, Nevada, and New York (whose law takes effect in June 2027). Requirements vary, but electronic wills generally need to be readable as text, signed electronically, and witnessed by at least two people. Most states still require paper wills with physical signatures, so check your state’s rules before going paperless.
Living Trust
A living trust names a person, called a trustee, to hold and distribute property and funds on your behalf when you’re no longer able to manage your affairs. Unlike a will, a trust avoids probate entirely, which means faster access for your beneficiaries and no public court filing. You typically serve as your own trustee while you’re alive and capable, with a successor trustee stepping in if you become incapacitated or after you die.
Not everyone needs a trust. If your estate is relatively simple, a will plus beneficiary designations on retirement accounts and insurance policies may be enough. Trusts become more valuable when you own property in multiple states, have a blended family, or want more control over how and when assets are distributed.
Financial Power of Attorney
A durable power of attorney for finances names someone to make financial decisions for you when you’re unable to. This person can pay bills, manage bank accounts, file taxes, sell property, and handle other business on your behalf. The word “durable” is critical: it means the authority continues even if you become incapacitated due to dementia, a brain injury, or another condition affecting mental function. A standard (non-durable) power of attorney would expire the moment you lost capacity, which is exactly when you’d need it most.
You can also limit the scope. Some people grant broad authority over all financial matters; others restrict it to specific accounts or transactions. Either way, this document needs to be in place before you lose the ability to sign one. Once you’re incapacitated without a financial power of attorney, your family may need to go to court for a guardianship or conservatorship, which is expensive, slow, and stressful.
Healthcare Power of Attorney
A healthcare power of attorney (sometimes called a healthcare proxy) designates another person to make medical decisions if you’re unable to communicate them yourself. This is separate from a living will. The healthcare proxy is a person; the living will is a set of written instructions. Ideally, you have both.
Healthcare providers and facilities are legally bound to follow your proxy’s decisions as if they were your own. You can also write specific instructions directly onto the proxy form, noting treatments you do or don’t want, or placing limits on your agent’s authority. Choose someone who understands your values, can handle pressure, and is willing to advocate on your behalf even if family members disagree.
Living Will
A living will tells doctors how you want to be treated if you’re terminally ill or permanently unconscious and can’t speak for yourself. It typically covers decisions like whether you want mechanical ventilation, tube feeding, dialysis, or resuscitation attempts. This document guides both your healthcare proxy and your medical team when specific situations arise.
One important nuance: not every state formally recognizes living wills as legally binding. Massachusetts, for example, allows healthcare proxies but doesn’t officially recognize living wills. Even in those states, a living will is still useful because it provides documented evidence of your preferences, giving your proxy and physicians clear guidance about the choices you would make.
POLST and DNR Orders
If you have a serious, life-limiting medical condition or advanced frailty, your doctor may recommend a POLST form (Physician Orders for Life-Sustaining Treatment, though names vary by state). Unlike a living will, which expresses your wishes, a POLST is an actual medical order signed by a clinician. Emergency responders and hospital staff treat it as a binding directive.
A POLST can include do-not-resuscitate (DNR) language, but it goes further. It lets you specify treatments you do want, not just those you refuse, and it covers situations beyond cardiac arrest, like whether to use antibiotics, IV fluids, or transfer to a hospital. Standard DNR orders in some states apply only outside a hospital and only when someone has stopped breathing or their heart has stopped. A POLST fills the gaps for patients whose medical reality is more complex.
POLST forms are not for healthy adults doing routine planning. They’re designed for people whose current health status makes a life-threatening event realistic in the near term.
Letter of Instruction
A letter of instruction is an informal document that covers the practical details your family will need immediately after your death. It doesn’t carry legal force like a will or trust, but attorneys involved in end-of-life planning widely recommend one because it answers the urgent questions that arise in the first 48 hours.
A typical letter includes:
- Location of important documents: where to find your will, trust, insurance policies, tax returns, and login credentials for online accounts
- Funeral and burial preferences: whether you want burial or cremation, which funeral home to contact, whether you want a religious or military service, who should deliver the eulogy, and a preferred charity for “in lieu of flowers” donations
- Personal property: specific items you want given to specific people, institutions, or charities (these can also be listed in a will or trust, but a letter makes them easier to find quickly)
Because this letter isn’t legally binding, keep it updated as circumstances change. It’s the one document you can revise casually without needing witnesses or a notary.
Digital Assets
Your digital life needs its own plan. Digital assets fall into three broad categories: financial accounts (online banking, credit cards, cryptocurrency, NFTs), business assets (websites, domain names, digital intellectual property), and personal accounts (email, social media, blogs). If nobody has your passwords or knows these accounts exist, they can be frozen, lost, or deleted.
One detail that surprises many people: digital purchases like music, movies, and ebooks are typically licenses, not property. You paid for the right to use them, not to own the underlying content, so they usually can’t be transferred to someone else. Cryptocurrency and domain names, on the other hand, do hold transferable value and should be documented carefully, including wallet keys and recovery phrases.
List your digital accounts, their purpose, and how to access them. Store this list securely, whether in a locked physical document, a password manager your executor can access, or both.
Making Your Documents Legal and Accessible
Requirements for witnesses, notarization, and other formalities vary significantly by state. Some states require two witnesses for advance directives, others require notarization, and some require both. Review your state’s specific instructions carefully, because a document that doesn’t meet your state’s requirements may not hold up when it matters most. Free state-specific advance directive forms are available through organizations like CaringInfo.
Once your documents are complete, distribute copies. Give them to your healthcare proxy, your financial agent, your lawyer, and your primary care doctor. Some states maintain registries where advance directives can be stored for quick access by healthcare providers. Keeping a wallet card that notes you have an advance directive, and where it’s stored, is a simple step that can make a real difference in an emergency.
Store originals in a secure but accessible location. A fireproof safe at home works better than a bank safe deposit box, which your family may not be able to open quickly after your death. Review and update all documents every few years, or whenever a major life event occurs: marriage, divorce, a new diagnosis, or the death of someone you’ve named as an agent.
