A complete estate plan rests on a small set of legal documents. Each one does a specific job: passing assets, naming decision-makers, protecting your family if you can’t speak for yourself, or reducing taxes. Missing even one can leave a gap that costs your heirs time, money, and privacy.
These are the core documents most families need, plus the ones that matter more as wealth and complexity grow:
| Name | What It Is | How to Get It |
| Last will and testament | Names who inherits your property, who serves as executor, and who would raise your minor children. | Drafted by an estate planning attorney, then signed with witnesses (and usually notarized) as your state requires. |
| Revocable living trust | Holds your assets during life and passes them to heirs privately, without probate. You keep control and can change it. | Drafted by an estate planning attorney and signed before a notary. You then fund it by retitling assets into the trust’s name. |
| Irrevocable trusts | Permanent trusts that move assets out of your taxable estate and can protect them from creditors. | Designed with an estate planning attorney and tax advisor. Assets are transferred to the trust, and a gift tax return may be required. |
| Durable financial power of attorney | Names an agent to manage your finances if you become incapacitated. | Drafted by your attorney with your other documents and signed before a notary. Some banks may also ask for their own form. |
| Healthcare power of attorney and living will | Names who makes medical decisions for you and records your wishes for end-of-life care. | Prepared by your attorney or on your state’s advance directive form, signed with witnesses or a notary, and shared with your doctors. |
| HIPAA authorization | Lets named people speak with your doctors and access your medical records. | Usually prepared by your attorney alongside your healthcare documents, then shared with your providers. |
| Beneficiary designations | Forms that decide who receives retirement accounts, life insurance, and transfer-on-death accounts. They override your will. | Completed directly with each account custodian or insurer, often online. Review them with your advisor so they match your plan. |
| Business succession documents | Buy-sell, operating, or shareholder agreements and a succession plan that govern who takes over your business. | Drafted by a business attorney with your co-owners, often with a valuation and life insurance to fund a buyout. |
| Letter of wishes and asset inventory | A non-binding letter explaining your intentions, plus a list of your accounts, assets, and advisors. | Written by you, often with your advisor’s help. Store it with your estate documents and update it regularly. |
Below, we explain what each document does and why it belongs in your plan. If you’re ready to start organizing, our 7-step estate planning checklist walks through the process.
1. Last Will and Testament
A will states who receives your property when you die and who will carry out your wishes. That person, your executor, gathers assets, pays debts and taxes, and distributes what remains.
For parents of minor children, the will does a second critical job: it nominates a guardian. Without that nomination, a court decides who raises your children.
A will has limits. Assets that pass under a will generally go through probate, a public court process that can be slow and costly. If you also have a living trust, your will is usually a “pour-over” will that sends any assets left outside the trust into it.
2. Revocable Living Trust
A revocable living trust holds your assets during your lifetime and passes them to your beneficiaries at death without probate. You typically serve as your own trustee, so you keep full control and can change or cancel the trust at any time.
The main benefits are privacy, speed, and continuity. Trust administration stays out of public court records. If you become incapacitated, your successor trustee can step in and manage the assets without a court-appointed conservator.
A trust only controls what it owns. Retitling real estate, brokerage accounts, and business interests into the trust’s name, known as funding, is what makes the document work. An unfunded trust is one of the most common estate planning mistakes.
3. Irrevocable Trusts
An irrevocable trust generally can’t be changed once it’s created. In exchange for giving up control, assets placed in it are usually removed from your taxable estate and can be shielded from creditors.
For families with significant wealth, these trusts are often where the real tax planning happens. Common types include:
- Irrevocable life insurance trust (ILIT): keeps life insurance proceeds out of your estate.
- Spousal lifetime access trust (SLAT): uses your exemption while leaving your spouse indirect access to the assets.
- Grantor retained annuity trust (GRAT): passes future growth on appreciating assets to heirs at little or no gift tax cost.
- Dynasty trust: holds wealth for multiple generations while limiting estate tax at each one.
The right structure depends on your assets, goals, and state law, so these are drafted with an estate planning attorney and coordinated with your tax advisor. For a closer look at how they fit together, see our guide to estate planning strategies for ultra-high-net-worth families.
4. Durable Financial Power of Attorney
A durable financial power of attorney names someone, your agent, to manage your financial affairs if you can’t. “Durable” means it stays in effect after you become incapacitated, which is exactly when it’s needed.
Your agent can pay bills, manage accounts, file taxes, and handle property not held in your trust. Without this document, your family may need to petition a court for guardianship or conservatorship before they can act.
Choose someone you trust completely and define their powers clearly. For complex estates, it matters whether your agent can make gifts, fund trusts, or deal with business interests on your behalf.
5. Healthcare Power of Attorney and Living Will
These two documents work together, and many states combine them into a single advance directive.
A healthcare power of attorney (sometimes called a healthcare proxy) names the person who makes medical decisions for you when you can’t make them yourself.
A living will records your wishes about end-of-life care, such as life support, resuscitation, and pain management. It guides your healthcare agent and your doctors, and it spares your family from guessing what you would have wanted during an already difficult time.
6. HIPAA Authorization
Federal privacy law limits who can see your medical information. A HIPAA authorization gives named people, such as your spouse, adult children, or healthcare agent, permission to speak with your doctors and access your records.
It’s a short document, but it prevents a frustrating problem: a family member who can’t get information from a hospital when it matters most. It also helps your successor trustee or financial agent obtain the medical confirmation of incapacity that many trusts and powers of attorney require.
7. Beneficiary Designations
Retirement accounts, life insurance policies, annuities, and transfer-on-death accounts pass directly to the people named on their beneficiary forms. These designations override your will and trust.
That makes them easy to overlook and costly to get wrong. An outdated form can send a large account to a former spouse, or leave assets to a minor outright instead of in trust.
Review every designation alongside your will and trust. Name contingent beneficiaries, and consider whether some accounts should name your trust rather than an individual. Retirement accounts deserve extra care because of the income tax rules on inherited IRAs.
8. Business Succession Documents
If you own a business, it may be the largest and least liquid asset in your estate. A will alone rarely addresses it well. Our guide to estate planning for business owners covers this in more depth.
Key documents include:
- Buy-sell agreement: sets who can buy your ownership interest, at what price, and how the purchase is funded, often with life insurance.
- Operating or shareholder agreement: governs how ownership transfers and who controls the company after a death or disability.
- Succession plan: names who will lead the business and how the transition will happen.
These documents protect the business’s value and help prevent disputes between family members, partners, and key employees. They should match the rest of your plan, especially if business interests are held in a trust.
9. Letter of Wishes and Asset Inventory
These aren’t legally binding, but they make every other document easier to carry out.
A letter of wishes explains the reasoning behind your plan. It can share your values, describe how you hope trustees will use their discretion, and give guidance on personal items or charitable goals. For multi-generational wealth, it helps the next generation understand not just what they’re receiving, but why.
An asset inventory lists your accounts, properties, business interests, insurance policies, digital assets, and key advisors. It saves your executor and trustee weeks of searching and reduces the chance that an asset is missed entirely.
Keeping Your Estate Plan Current
Signing these documents is the start, not the finish. Review your plan every three to five years, and right away after a major change: a marriage or divorce, a birth or death in the family, a move to another state, a business sale, or a shift in tax law.
The documents also need to work together. Your trust, will, beneficiary forms, and business agreements should point in the same direction. Coordinating them across your attorney, tax advisor, and wealth advisor is what turns a stack of paperwork into a plan that protects your family, and it’s at the center of how we approach estate planning.
