A will is the foundation of any estate plan — but it's rarely sufficient on its own. A complete estate plan includes a will, beneficiary designations, potentially a trust, a durable power of attorney, and advance healthcare directives. Together, these documents ensure your assets go where you want, your family is protected, and your wishes are honored.
This guide covers everything you need to know about wills and estate planning: the different types of documents, what they do, how they work together, and how to keep your plan current.
What Is a Will?
A last will and testament is a legal document that specifies how your assets should be distributed after your death, who should manage that process (your executor), and — if you have minor children — who should raise them (your guardian). A will that goes through the court process is called a "testamentary will," and the distribution process is called probate.
Without a will, you die "intestate," and your state's default succession laws determine who inherits your estate. These laws prioritize legal relatives in a specific order that may not reflect your actual wishes — especially if you're unmarried, have a blended family, or want to leave assets to non-relatives or charities.
Types of Wills
Not all wills are created equal. The main types include:
- Simple will: A straightforward document specifying asset distribution. Suitable for most people with uncomplicated estates.
- Testamentary trust will: Creates a trust upon death, allowing assets to be managed for beneficiaries over time — often used for minor children or beneficiaries who need financial oversight.
- Pour-over will: Works alongside a living trust, directing any assets not already in the trust to "pour over" into it at death.
- Holographic will: Handwritten and signed (but not witnessed). Valid in some states, but more vulnerable to legal challenge.
Our guide to types of wills explains each in detail and helps you determine which is right for your situation.
What to Include in Your Will
A well-drafted will should cover:
- Identification of your assets and how each should be distributed
- Named beneficiaries for each asset or asset category
- Appointment of an executor
- Naming of a guardian for minor children
- Contingency plans (what happens if a beneficiary predeceases you)
- Instructions for debts, taxes, and expenses
- Any specific bequests (personal items of sentimental value)
See our detailed guide on what to include in your will.
Trusts: When a Will Isn't Enough
A living trust (also called a revocable trust) can complement or replace aspects of a will. Its key advantages are:
- Avoiding probate: Assets held in a trust pass to beneficiaries without going through the court process — saving time, cost, and privacy.
- Continuity: A trust takes effect immediately and can manage assets during incapacity as well as after death.
- Control: You can specify exactly when and how beneficiaries receive assets.

Choosing an Executor
Your executor (called a "personal representative" in some states) is responsible for filing your will with the probate court, managing your estate during probate, paying your debts and taxes, and distributing assets to beneficiaries. It's a significant responsibility that can last months or years. See our guide on how to choose an executor.
Beneficiary Designations: The Will Override
One of the most important — and most misunderstood — aspects of estate planning is that certain accounts pass directly to named beneficiaries, bypassing your will entirely. This includes retirement accounts (IRAs, 401(k)s), life insurance policies, and accounts with payable-on-death designations. Outdated beneficiary designations are among the most common estate planning mistakes. Read more in our guide to beneficiary designations.
Keeping Your Plan Updated
An estate plan is not a set-it-and-forget-it document. It should be reviewed after any major life change — marriage, divorce, new children, significant asset changes, or the death of a named beneficiary. See our guide on when and how to update your will.
Do You Need an Attorney?
Simple estates can sometimes be handled with online tools or legal software. But complex situations — large estates, blended families, business ownership, special needs beneficiaries, significant real estate — generally benefit from professional legal help. Our guide to working with an estate attorney helps you decide when professional help is worth it.
