What Documents Do I Need for Estate Planning?

Most people think estate planning means writing a will. It does not. A will is one document in a package of five to seven that together protect your family, your assets, and your wishes if you die or become incapacitated. Without the full set, gaps in your plan force your family into court, cost thousands in legal fees, and can expose your home to creditor claims.

The Core Documents Every Adult Needs

1. Last Will and Testament

Your will names who receives your assets, who manages your estate (the Personal Representative or executor), and who raises your minor children. Without one, your state's intestacy laws dictate distribution — and they do not care about your preferences.

A will does not avoid probate. Assets passing through a will still go through court. But a will gives you control over the process — who is in charge, who gets what, and how disputes should be resolved.

2. Durable Financial Power of Attorney

This document names an agent to manage your financial affairs if you become incapacitated — paying bills, accessing bank accounts, managing investments, filing taxes, and conducting real estate transactions on your behalf.

The word "durable" is critical. A standard power of attorney dies when you become incapacitated — the exact moment you need it most. A durable POA includes specific language ensuring it survives your incapacity.

Without a durable POA, your family must petition the court for a conservatorship to access your bank accounts or pay your mortgage. Conservatorship proceedings cost $3,000 to $10,000 and take months.

3. Advance Healthcare Directive

This combines two functions: naming a healthcare agent (the person who makes medical decisions when you cannot) and recording your treatment preferences for end-of-life situations.

Your healthcare agent can consent to or refuse treatment, choose doctors and hospitals, access your medical records, and make decisions about life-sustaining treatment. Without this document, doctors must follow a statutory hierarchy of decision-makers — which may not match who you would want making those calls.

4. HIPAA Authorization

Federal privacy law restricts who can access your medical information. Even your spouse or adult children cannot review your medical records without authorization. A HIPAA release form names the people who can access your health information, ensuring your healthcare agent and family members can make informed decisions.

This is often overlooked and is frequently the document that causes the most frustration during a medical crisis. Include it with your healthcare directive.

5. Beneficiary Designations

These are not a single document but a set of designations on your financial accounts. Life insurance policies, retirement accounts (401k, IRA), bank accounts (payable-on-death), and investment accounts (transfer-on-death) all allow you to name beneficiaries who inherit the asset directly — outside of probate.

Beneficiary designations override your will. If your will leaves everything to your children but your life insurance still names your ex-spouse from a decade-old form, the ex-spouse gets the insurance proceeds.

Review every beneficiary designation as part of your estate plan. This is the most common source of estate planning failures.

6. Transfer on Death Deed (Where Available)

If your state allows it (and many do, including New Mexico, Arizona, Colorado, and about 30 others), a transfer on death deed lets you designate a beneficiary for your real estate. The deed transfers the property automatically at death, bypassing probate entirely.

The owner keeps full control during their lifetime — they can sell, refinance, or revoke the deed at any time. The beneficiary has no ownership interest until the owner dies.

For homeowners who do not want the cost of a revocable living trust, a TODD paired with a simple will achieves most of the same goals for a fraction of the cost.

7. Revocable Living Trust (Optional)

A trust is a legal entity that owns your assets and distributes them to beneficiaries according to your instructions, without probate court involvement. It is the most comprehensive probate-avoidance tool but also the most expensive to set up — typically $1,000 to $4,500 with an attorney.

A trust is most valuable when you:

• Own real estate in multiple states (each state would require a separate probate)
• Want to maintain complete privacy (probate is a public proceeding; trusts are not)
• Have a complex family situation (blended families, minor beneficiaries, special needs)
• Own a business that needs seamless management if you die or become incapacitated

For a single home and standard family situation, a will plus TODD plus beneficiary designations usually achieves the same result at much lower cost.

Documents to Keep With Your Estate Plan

Your estate planning documents are only useful if your family can find them and if the supporting information is organized. Keep these alongside your legal documents:

• Asset inventory: A complete list of your bank accounts, investment accounts, insurance policies, real estate, and debts — including account numbers, institution names, and approximate values
• Digital asset inventory: Passwords, account credentials, cryptocurrency wallet information, and instructions for accessing your digital accounts
• Contact list: Your attorney, CPA, financial advisor, insurance agent, and the location of your safe deposit box and its key
• Certified copies of vital records: Marriage certificates, divorce decrees, military discharge papers (DD-214), and Social Security cards

The Cost of Not Having These Documents

A missing durable POA can cost $3,000 to $10,000 in conservatorship proceedings. A missing will can add $5,000 to $15,000 in contested probate costs. Missing beneficiary designations on a retirement account can trigger unnecessary income taxes for your heirs.

The complete set of estate planning documents costs $150 to $500 if you use a DIY approach or $1,500 to $5,000 with an attorney for a basic plan. The New Mexico Basic Estate Planning Kit covers all the essential documents with templates and step-by-step instructions tailored to state-specific requirements.
