Besides a will, the legal documents most adults need are a durable power of attorney for finances, an advance healthcare directive that includes a healthcare proxy and HIPAA authorization, and up-to-date beneficiary designations on every account that has one. Parents of minor children also need a guardian nomination. Depending on what you own and how much privacy you want, a revocable living trust, a plan for digital accounts, and a letter of intent round out the set. A will handles who gets your property after you die. These other documents handle everything a will cannot: incapacity, medical decisions, accounts that pass by contract, children who still need a parent, and the practical access your family will need when the time comes.
Durable Power of Attorney for Finances
A financial power of attorney names someone to handle your money and property if you cannot. That person, called your agent or attorney-in-fact, can pay bills, manage investments, file taxes, and handle real estate transactions on your behalf.1Legal Information Institute. Attorney-in-Fact Without one, your family would have to petition a court for a conservatorship or guardianship to manage your finances if you became incapacitated. That process costs thousands and can take months.
Most estate planners recommend the durable version, which takes effect when you sign it and stays in force even if you lose capacity. The alternative, a springing power of attorney, only activates after a triggering event, usually a physician certifying in writing that you can no longer manage your affairs. In practice, springing powers create delays: doctors are cautious about declaring someone incapacitated, banks sometimes refuse to honor the document until every detail is nailed down, and family members may disagree about whether the trigger has been met.
Your agent owes you a fiduciary duty and cannot use your money for themselves or make gifts from your assets unless the document specifically allows it. The authority also ends at your death, at which point your executor or trustee takes over.
Advance Healthcare Directive
Healthcare directives tell doctors what you want and who speaks for you when you cannot communicate. Most states combine the pieces into a single form, but the components do different jobs.
Living Will
A living will is a written statement of your treatment preferences if you are terminally ill or permanently unconscious. It addresses specifics such as whether you want a ventilator, whether you want artificial nutrition through a feeding tube, and what level of comfort care you prefer.2National Institute on Aging. Preparing a Living Will It gives your medical team clear guidance instead of leaving your family to guess.
A living will only covers the scenarios you anticipated when you wrote it, and medical emergencies rarely unfold exactly as expected. That is why it is not enough on its own.
Healthcare Proxy
A healthcare proxy, sometimes called a medical power of attorney, appoints someone to make medical decisions for you when you cannot. Your agent can talk to doctors, review your records, choose treatment options, select care facilities, and make the calls your living will does not address.3National Institute on Aging. Choosing a Health Care Proxy The range of decisions here is broader than anything a living will can anticipate, which makes the proxy the most consequential piece of your medical paperwork.
Pick someone who will follow your wishes even when they disagree, and who can advocate firmly in a hospital setting. A spouse is the default choice for many people but not always the best one, particularly if your spouse would struggle with end-of-life decisions.
HIPAA Authorization
Federal privacy rules prohibit healthcare providers from sharing your medical information without your written permission.4U.S. Department of Health and Human Services. The HIPAA Privacy Rule A HIPAA authorization form names the people who can access your records. A valid authorization has to identify the specific information covered, who can receive it, the purpose, and an expiration date or event.5eCFR. 45 CFR 164.508 – Uses and Disclosures for Which an Authorization Is Required
Without it, your healthcare proxy may not be able to get the information they need to make informed decisions. Some states build HIPAA-compliant language into their standard directive forms, but many do not, so a standalone release signed alongside your other documents removes the ambiguity.
Beneficiary Designations
Some of your most valuable assets never pass through your will. Life insurance policies, 401(k)s, IRAs, annuities, and payable-on-death bank accounts all go directly to whoever is listed on the beneficiary form. Those designations are contracts with the financial institution, and they override your will. For employer-sponsored retirement accounts, federal law requires plan administrators to pay benefits according to the designation on file regardless of what your will or even a divorce decree says.6U.S. Department of Labor. Current Challenges and Best Practices Concerning Beneficiary Designations in Retirement and Life Insurance Plans
The common failure: your will leaves everything to your current spouse, but your ex-spouse is still listed on a 401(k) from before the divorce. The account goes to the ex. Review every designation after marriage, divorce, the birth of a child, or the death of a beneficiary, and name contingent beneficiaries in case your primary beneficiary dies before you do.
Guardian Nomination for Minor Children
If you have children under 18, naming a guardian is one of the most consequential decisions in your estate plan. The nomination tells the court who you want to raise your children if both parents die or become permanently unable to care for them. Without it, a judge chooses based on state law, and the result may not be who you would have picked.
Most states require the nomination to appear in your will, though some allow a separate standalone document. The nomination is not automatically binding on the court, but judges give heavy weight to a parent’s stated preference and will usually follow it unless there is a strong reason not to.
Consider naming a standby guardian in a separate document as well. A standby guardian has temporary authority to care for your children during a short-term emergency, such as a hospitalization or a stretch when you are unreachable. Without this designation, family services and a court may need to get involved to authorize someone else to make decisions for your children, even temporarily. Ideally the standby lives close enough to step in quickly.
Revocable Living Trust
A revocable living trust is a legal arrangement where you transfer ownership of your assets into a trust that you control during your lifetime. You typically serve as your own trustee and manage everything exactly as before, and you can change the terms or dissolve the trust whenever you want.7Consumer Financial Protection Bureau. What Is a Revocable Living Trust When you die, a successor trustee you named distributes the assets to your beneficiaries.
The main reason people create one is probate avoidance. Assets inside the trust pass to beneficiaries without going through the court-supervised probate process, which means faster access, lower cost, and privacy. Probate is a public proceeding, so anyone can look up what you owned and who inherited it. A trust keeps that private.
Funding the Trust
This is where most people make their biggest estate planning mistake. A trust only controls assets that have actually been transferred into it. If you create a trust but never retitle your house, bank accounts, or investment accounts in the trust’s name, those assets go through probate anyway as if the trust did not exist.7Consumer Financial Protection Bureau. What Is a Revocable Living Trust Funding means changing legal ownership on each asset: a new deed for real estate, recorded with the county; updated account titles at every bank or brokerage; a revised homeowner’s insurance policy reflecting the new ownership. The process is not complicated, but it requires follow-through on every asset.
Pour-Over Will
Even with a well-funded trust, you will almost certainly acquire new property over the years that you never got around to transferring in. A pour-over will acts as a safety net. It directs that any assets left outside the trust at your death are poured into it and distributed under its terms. Those assets still pass through probate, but they end up where you intended rather than under your state’s default inheritance rules. If you have a revocable living trust, you need a pour-over will alongside it.
Transfer-on-Death Deed as an Alternative
If your main goal is avoiding probate on your home and a full trust feels like too much, roughly 30 states allow transfer-on-death deeds for real estate. You sign a deed naming a beneficiary, record it with the county, and the property passes automatically at your death. You keep full ownership and control while you are alive, and you can revoke the deed whenever you want. A TOD deed only covers one property and does nothing for incapacity, so it fills a narrower slot than a trust.
Digital Asset Access
Your digital life includes email, social media, cloud storage, cryptocurrency wallets, online banking, and subscription services. When you die or become incapacitated, someone needs both the legal authority and the practical ability to reach these accounts. Most tech companies will not hand over login credentials to your family without proper legal authorization, even with a death certificate.
Nearly every state has adopted a version of the Revised Uniform Fiduciary Access to Digital Assets Act, which gives your executor, trustee, or agent the legal right to manage your digital property.8Uniform Law Commission. Fiduciary Access to Digital Assets Act, Revised Many platforms also let you set preferences through their own tools, and those settings can override what your estate plan says. Facebook lets you name a legacy contact. Google has an Inactive Account Manager. Apple has a Digital Legacy program. Check the settings on your major accounts and make sure they match your plan.
Practically, keep an inventory of accounts, login credentials, and two-factor authentication methods somewhere your agent or executor can reach it. A password manager with an emergency access feature is one approach. You can reference the inventory in your letter of intent without listing passwords in a document that might be filed with a court.
Letter of Intent
A letter of intent is a personal, non-binding document that fills gaps your legal paperwork leaves. Your will says who gets what. Your letter explains why, and it provides the practical details your executor and family need to carry out your plan: funeral preferences, the reasoning behind unequal distributions, personal messages, instructions for pet care, and where to find important documents and account information. Because it is not legally binding, it is easy to update as your circumstances change.
Keeping Documents Current
Estate plans break down when they go stale. Review your documents every three to five years and after any major life change: marriage, divorce, a new child, a death in the family, a significant change in assets, or a move to a different state. State laws governing powers of attorney and healthcare directives vary, and a document valid where you signed it may not work the same way after you relocate. Pay particular attention to beneficiary designations and trust funding, because those are the two areas where outdated information causes the most damage.
