Last Will and Testament: What It Is, What It Does, and Why "I'll Get to It" Is the Most Expensive Sentence in Estate Planning

What Is a Last Will and Testament?

A Last Will and Testament — most people just call it a "will" — is a legal document that records your wishes for what happens to your property, your money, and your responsibilities after you die.

It tells the world: who gets what, who takes care of any minor children, and who is in charge of carrying out your instructions. Without it, your state government makes those decisions for you — using a formula that has no way of knowing who you loved, what you promised, or what mattered most to you.

A will is not just for wealthy people. It's for anyone who owns anything, cares about anyone, or wants any say in what happens after they're gone. That's most of us.

What Does a Will Actually Do?

A will serves several distinct and important functions:

Distributes your assets

You name who receives your property — your home, your car, your bank accounts, your personal belongings, your investments. You can divide things however you choose: equally among children, in specific percentages, with specific items going to specific people.

Names a guardian for minor children

If you have children under 18, your will is where you name who would raise them if both parents died. This is arguably the most important function of a will for parents of young children — and yet it's the reason many young parents still don't have one, because the conversation feels too dark to start.

Names an executor

Your executor (sometimes called a personal representative) is the person responsible for carrying out the instructions in your will — paying your debts, gathering your assets, filing final tax returns, and distributing what's left to your beneficiaries. This is a practical, administrative role and the person who fills it needs to be organized, reliable, and trustworthy.

Expresses specific wishes

Beyond the financial, a will can express wishes about your funeral and burial arrangements, the care of pets, personal messages to family members, and charitable gifts.

Why You Need One

The most common reason people don't have a will is that they haven't gotten around to it. The most common reason that turns into a disaster is that they run out of time before they do.

Here's what having a will actually gives you:

• Control. The single most important thing. Without a will, your state's intestacy laws decide who gets your assets. Those laws follow a fixed formula — typically prioritizing spouses, then children, then other relatives — that cannot account for your specific relationships, your specific promises, or your specific situation.
• Protection for the people you love most. A will lets you leave more to a child who needs it more, protect a family member with special needs without affecting their government benefits (through careful planning), or ensure that a person who isn't a legal relative but who matters deeply to you receives something.
• Clarity that prevents conflict. Wills don't eliminate family conflict — but the absence of a will dramatically increases it. When there's no document, every family member's version of "what Mom/Dad would have wanted" becomes equally valid and equally contested.
• Speed. Estates with clear wills move through probate — the legal process for validating a will and distributing assets — significantly faster than intestate estates (those without a will).

What Happens If You Die Without a Will

Dying without a will is called dying intestate. When that happens, your state's intestacy laws take over. Here's what that actually means:

• Your assets go where the formula sends them — not where you would have sent them. In most states, a spouse and children split the estate. But what if your spouse remarried and you're estranged? What if one child needs much more support than the others? What if the person you lived with for 20 years isn't legally your spouse? The formula doesn't know.
• Unmarried partners get nothing in most states, regardless of the length or depth of the relationship. If you've built a life with someone you're not legally married to, and you die without a will, they may receive nothing while distant relatives you barely know inherit.
• Blended families can become battlegrounds. Step-children typically have no inheritance rights without a will. Your biological children and your stepchildren may receive dramatically unequal treatment under intestacy laws — which may not reflect your wishes at all.
• Someone you wouldn't choose may be appointed guardian of your minor children. Courts try to act in children's best interests, but without your documented preference, they're working without the most important piece of information.
• The process takes longer and costs more. Intestate estates typically take longer to settle and generate more administrative and legal costs than estates with clear wills.

How to Choose Your Executor

Your executor doesn't need a law degree. They need to be organized, responsible, and trustworthy. They'll be dealing with banks, courts, creditors, and beneficiaries — often while also grieving.

Look for someone who:

• Is highly organized and follows through on tasks reliably
• Can manage paperwork, deadlines, and communications with professionals
• Is trusted and respected by your other beneficiaries (conflict with beneficiaries is the executor's daily challenge)
• Is not likely to be so emotionally overwhelmed that they can't function
• Has the time — settling an estate can take a year or more

Practical considerations:

Your executor doesn't have to be a family member. A trusted friend, a professional fiduciary, or even a bank trust department can serve. For complex estates, a professional executor may actually be the better choice — they bring expertise and neutrality.

Name a backup executor, always. Your primary choice may predecease you, be unwilling to serve when the time comes, or be incapacitated.

Same person as financial agent? Often yes — the organizational skills and trustworthiness required overlap significantly. But the roles are different: your financial POA agent acts during your lifetime; your executor acts after your death.

How to Have the Conversation

Talking to your family about your will is one of the most loving things you can do — and one of the most avoided. Here's how to make it easier.

For parents talking to adult children:

"I've been getting my affairs in order, and I wanted you to know what I've put in my will — not because I'm planning on going anywhere, but because I don't want there to be any surprises or confusion later. I'd rather we talk about it now."

Walk them through the broad strokes: who the executor is and why you chose them, how assets are generally distributed and the reasoning behind any choices that might surprise them, and where the will is kept.

For adult children raising the topic:

"I know this isn't a fun conversation, but I've been thinking about whether you and Dad have a will and whether it's current. I don't need to know the details — I just want to know that it's been handled."

The most important thing to communicate: Not the details of who gets what, but the fact that there is a plan, where the document lives, and who the executor is. The rest can remain private.

Addressing the difficult choices:

If you've made choices that might surprise or hurt family members — leaving more to one child than another, leaving something to someone outside the family, excluding someone — consider addressing it directly with those involved rather than letting them discover it after you're gone. It doesn't have to be a negotiation. It's an explanation.

"I want to tell you something about my will while I can explain my thinking. I've left a larger share to [person] because [reason]. I hope you understand, and I want you to hear it from me."

How to Create One

Option 1 — Online service

For straightforward situations — married with children, clear assets, no complex family dynamics — an online service can create a legally valid will at a fraction of the attorney cost. Our partner Gentreo includes a will as part of their complete estate plan, starting at $99/year.

Option 2 — Elder-law or estate attorney

Strongly recommended for: blended families, significant assets, real estate in multiple states, a family member with special needs, business ownership, charitable giving intentions, or any complexity at all. Cost: $400–$1,200, often significantly less when bundled with other estate planning documents.

What to avoid: Handwritten wills (valid in some states but risky) and generic internet templates downloaded from unvetted sources. Your will needs to meet your state's specific execution requirements — proper witnesses, no beneficiaries as witnesses, correct signatures. Errors can invalidate the document or specific provisions.

Keeping Your Will Current

A will is not a one-and-done document. Review it — and potentially update it — after:

• Marriage or divorce
• Death of a named beneficiary, executor, or guardian
• Birth or adoption of a child or grandchild
• Significant change in your assets
• Moving to a different state (wills are generally valid across states, but it's worth confirming)
• A major change in your relationship with someone named in the document
• Any significant change in your wishes

A good rule of thumb: review your will every 3–5 years at minimum, even if nothing obvious has changed.

Common Mistakes to Avoid

• Outdated beneficiary designations on accounts. Your will doesn't govern accounts with named beneficiaries. If your will leaves everything to your current spouse but your life insurance still names your ex-spouse, the insurance pays your ex. Review beneficiary designations annually.
• Forgetting digital assets. Your email, social media, online banking, cryptocurrency, and digital photos all have a kind of afterlife. Consider including instructions for digital assets — and make sure someone has the passwords or access information.
• Naming a minor child as a direct beneficiary. Minors can't legally inherit directly. If you want to leave assets to a child, name a custodian under the Uniform Transfers to Minors Act, or establish a trust.
• Not telling your executor where the will is. This happens more than you'd think. Your executor needs to know — before they need to know.
• Storing it somewhere inaccessible. A safe deposit box sounds secure, but accessing it after your death may require court involvement. Keep the original somewhere your executor can access it — a fireproof home safe, with your attorney, or registered with your state's will registry if one exists.
