Estate Planning Basics: Wills, Trusts, and Power of Attorney Explained for Every Adult

Why Does Everyone Need an Estate Plan?

If you die without a will (called dying intestate), state law determines who inherits your assets — and it may not match your wishes. Your partner of 20 years gets nothing if you are not legally married. Your estranged sibling might inherit equally with your children. Your minor children guardianship is decided by a judge who has never met your family. Estate planning is not about being wealthy — it is about maintaining control over what happens to your assets, your dependents, and your medical care when you cannot speak for yourself. Yet over 60% of American adults do not have a will.

What Is the Difference Between a Will and a Trust?

A will is a legal document that specifies how your assets should be distributed after death. It goes through probate — a court-supervised process that can take 6-18 months and cost 3-7% of the estate value in legal fees. A revocable living trust holds your assets during your lifetime and transfers them to beneficiaries upon death without probate. Trusts are private (wills become public record), faster, and avoid probate costs. However, trusts are more expensive to set up ($1,500-$3,000 vs $300-$1,000 for a will) and require you to retitle assets into the trust. For most people with straightforward situations, a will plus beneficiary designations on retirement accounts is sufficient. Trusts become valuable when you have significant assets, real estate in multiple states, or complex family situations.

What Is a Power of Attorney and Why Do You Need One?

A financial power of attorney (POA) designates someone to manage your finances if you become incapacitated — paying bills, managing investments, filing taxes. A healthcare power of attorney (also called a healthcare proxy) designates someone to make medical decisions on your behalf. Without these documents, your family may need to go to court to obtain guardianship, which is expensive, time-consuming, and emotionally draining. A living will (advance directive) specifies your wishes for end-of-life medical care. These three documents — financial POA, healthcare POA, and living will — are arguably more important than a will because they protect you while you are still alive.

How Do Beneficiary Designations Work?

Retirement accounts (401k, IRA, Roth IRA), life insurance policies, and bank accounts with payable-on-death designations pass directly to named beneficiaries outside of probate — regardless of what your will says. This is critical: if your will leaves everything to your current spouse but your 401(k) still lists your ex-spouse as beneficiary, your ex gets the 401(k). Review and update beneficiary designations after every major life event: marriage, divorce, birth of a child, or death of a beneficiary. This is the single most common estate planning mistake and one of the easiest to fix.

How to Get Started With Estate Planning in 2026

For a simple estate plan, online services like Trust and Will, LegalZoom, or Nolo offer will packages for $100-$300. For more complex situations (trusts, blended families, business ownership, estates above the federal estate tax exemption of $13.6 million), hire an estate planning attorney — expect to pay $1,500-$5,000 for a comprehensive plan. At minimum, every adult should have: a will, a financial power of attorney, a healthcare power of attorney, a living will, and updated beneficiary designations on all accounts. Store originals in a fireproof safe and give copies to your executor and healthcare proxy. Review your plan every 3-5 years or after major life changes.
