Estate planning is how you decide who gets your money, property, and possessions after you die, and who makes medical and financial decisions if you cannot

Without a plan, state law decides for you — and the process takes months, costs thousands in court fees, and may not match what you wanted. Estate planning is not just for the wealthy. It applies to anyone with a bank account, a home, a car, or people who depend on them. The documents you create now prevent confusion, reduce family conflict, and can save your heirs significant time and money.

Most seniors need four core documents: a will, a healthcare power of attorney, a financial power of attorney, and a living will (also called an advance directive). Some also use trusts to avoid probate or protect assets. The cost and complexity depend on your situation — a straightforward will costs $300 to $1,000 through an attorney, while a DIY online will costs $50 to $200. A trust costs more upfront but can save money later.

Key Takeaways

  • A will, healthcare power of attorney, financial power of attorney, and living will are the four documents most seniors need to have in place.
  • Without these documents, state law decides who inherits your property and who makes decisions about your medical care and finances — a process called probate that can take six months to two years.
  • You can create basic documents yourself through online services for $50 to $200, or work with an attorney for $1,000 to $3,000 depending on complexity.
  • Naming a healthcare power of attorney and financial power of attorney means someone you trust can act on your behalf if you become unable to do so yourself.
  • A living will documents your wishes about life-sustaining medical treatment so your family does not have to guess what you would want.

The four documents every senior should have

A will is a legal document that names who inherits your property and who manages your estate after you die. It also names a guardian for minor children if you have them. Without a will, your state's intestacy laws decide who gets what — usually a formula that gives money to spouses and children in a set order, regardless of your preferences. A will must be signed in front of witnesses (usually two, sometimes three depending on your state) and notarized to be valid.

A healthcare power of attorney (also called a healthcare proxy or medical power of attorney) names someone to make medical decisions for you if you cannot. This person can talk to doctors, see your medical records, and decide about treatment — including whether to continue life support. Without this document, your family may have to go to court to get legal authority to make decisions, which delays care and costs money.

A financial power of attorney names someone to manage your money and property if you become unable to do so. This person can pay bills, access bank accounts, sell property, and file taxes on your behalf. You can make this power effective when ready (so the person can act while you are still alive) or only if you become incapacitated — the choice is yours.

A living will (or advance directive) documents your wishes about life-sustaining medical treatment — whether you want to be resuscitated if your heart stops, whether you want a feeding tube if you cannot eat, and other end-of-life choices. This is separate from a healthcare power of attorney. The power of attorney makes decisions; the living will tells them what decisions to make.

What happens if you die without a plan

If you die without a will or trust, your estate goes through probate — a court process where a judge decides who inherits your property based on state law. Probate is public (anyone can see what you owned and who got it), slow (usually six months to two years), and expensive (court fees, attorney fees, and executor fees typically total 3 to 7 percent of the estate's value). For a $200,000 estate, that can mean $6,000 to $14,000 in costs.

During probate, your property is frozen — your heirs cannot access bank accounts or sell the house until the court releases it. If you have minor children and no named guardian, the court decides who raises them. If you have no will and no close relatives, your property goes to the state.

If you become incapacitated without a healthcare or financial power of attorney, your family must petition the court for guardianship or conservatorship — another expensive, public process that can take weeks or months. During that time, no one has legal authority to make decisions or pay your bills.

Wills versus trusts — when you need each

A will is simpler and cheaper but does not avoid probate. It takes effect only after you die and only after going through the court. A will is the right choice if your estate is small (under $100,000), you have no minor children, and you do not mind probate.

A trust is a legal arrangement where you transfer property into a fund managed by a trustee (often yourself while you are alive) for the benefit of your heirs. A revocable living trust avoids probate because the property is not part of your estate when you die — it is already in the trust. The trust is private, takes effect when ready, and can be changed or cancelled anytime while you are alive. The downside is higher upfront cost ($1,500 to $3,000 or more) and more paperwork (you have to retitle property in the trust's name).

Many seniors use both: a will as a backup (called a "pour-over will") and a trust as the main vehicle. This covers property you forget to put in the trust and ensures nothing falls through the cracks.

How to create your estate plan

You have three main routes: do it yourself online, work with an attorney, or use a combination. Online services like LegalZoom, Nolo, and Rocket Lawyer let you answer questions and generate documents for $50 to $200. These work well for straightforward situations — you are married, you have a few bank accounts and a house, and you want everything to go to your spouse or adult children. The documents are state-specific and legally valid if you follow the signing and notarization rules.

An attorney costs more ($1,000 to $3,000 for a basic package) but is worth it if your situation is complex — you own a business, you have significant assets, you have been married more than once, or you want to minimize taxes. An attorney can also spot issues you might miss (like naming someone as executor who lives out of state or is too elderly to serve). Many attorneys offer flat fees for basic estate planning, so ask upfront what is included.

To find an attorney, ask your doctor, friends, or local bar association for referrals. Many offer a free initial consultation where you can ask questions and get a sense of their approach. Make sure they are licensed in your state — estate law varies by state, and a document valid in one state may not be in another.

Storing your documents and telling people where they are

Once your documents are signed and notarized, store the originals in a safe place — a safe deposit box at your bank, a home safe, or with your attorney. Keep copies at home where your family can find them. Do not store originals in a safe deposit box alone; banks may seal the box after you die, and your family will need a court order to open it.

Tell your healthcare power of attorney and financial power of attorney where the documents are and how to access them. Give them a copy. Tell your spouse or adult children where to find your will and living will. Write down the names and phone numbers of your attorney, accountant, and financial advisor, and keep that list with your documents.

Some people create a "letter of instruction" — a straightforward document (not legally binding) that lists your accounts, passwords, insurance policies, funeral wishes, and where to find important papers. This saves your family hours of searching and guessing.

Updating your plan when life changes

Review your estate plan every three to five years, or sooner if your life changes significantly. Major changes that require updates include marriage or divorce, the birth of grandchildren, a significant change in your assets, a move to a different state, or a change in who you want to inherit your property or make decisions for you.

You can update a will by creating a new will (which automatically cancels the old one) or by adding a codicil (a legal amendment). Updating a trust is simpler — you just amend it. If you move to a new state, check whether your documents are still valid there; some states recognize out-of-state wills and powers of attorney, but rules vary.

If a person you named as executor, power of attorney, or healthcare proxy dies or becomes unable to serve, update your documents to name a replacement. This is one of the most common oversights — people name someone, years pass, and that person is no longer able or willing to serve.

Common mistakes to avoid

Naming the wrong person as executor or power of attorney is a frequent mistake. Choose someone organized, trustworthy, and willing to do the job — not necessarily your oldest child or closest relative. Executors and powers of attorney have legal duties and can be held liable if they mishandle money or property. Make sure the person you name understands what the role involves and agrees to take it on.

Forgetting to sign and notarize documents properly is another common error. A will or power of attorney that is not signed correctly is invalid and worthless. Follow your state's rules exactly — some states require two witnesses, others three; some require notarization, others do not. If you use an online service, it will guide you through the signing process. If you work with an attorney, they will handle it.

Not putting property into a trust is a third mistake. If you create a revocable living trust but do not retitle your house, bank accounts, and investments in the trust's name, they will still go through probate. This is extra work, but it is essential to the plan working as intended.

Naming a minor as a beneficiary without a guardian is also problematic. If you leave money to a grandchild under age 18, the court will appoint a guardian to manage it — which may not be who you would have chosen. Instead, name a trusted adult as guardian or set up a trust with that adult as trustee.

Frequently Asked Questions

Do I need an attorney to create a will or power of attorney?

No. Online services and DIY kits are legally valid if you follow your state's signing and notarization rules. An attorney is most useful if your situation is complex — you own a business, have significant assets, have been married more than once, or want to minimize taxes. For a straightforward situation, an online service or DIY kit is usually sufficient.

What happens to my debts and taxes after I die?

Your estate pays your debts and taxes before your heirs receive anything. This includes credit card debt, medical bills, mortgages, and income taxes. Your executor or trustee is responsible for paying these. Federal estate tax applies only to very large estates (over $13.61 million in 2024, though this amount changes yearly), so most seniors do not owe federal estate tax. Some states have their own estate or inheritance taxes.

Can I change my will or trust after I create it?

Yes. You can create a new will (which cancels the old one), add a codicil (an amendment), or amend a trust. You can change your power of attorney or healthcare proxy at any time. The only document you cannot change after you die is your living will — it takes effect when you can no longer communicate your wishes.

What if I do not have much money — do I still need a will?

Yes. Even a small estate benefits from a will because it avoids probate, keeps your wishes private, and names a guardian for minor children if you have them. A will also names an executor — the person who will handle your affairs — so your family does not have to figure it out. A straightforward will costs $50 to $200 online or $300 to $500 through an attorney.

Who should I name as my healthcare power of attorney?

Choose someone you trust completely, who knows your values and wishes, and who is willing to make difficult medical decisions. This is often a spouse or adult child, but it can be anyone. Make sure they live close enough to be available in an emergency and that they understand they may have to advocate for you with doctors. Tell them where your living will is and what your wishes are about end-of-life care.
