Estate Planning for New Parents: The 4 Documents You Need Right Now

10 min read

Why Having a Baby Changes Everything for Estate Planning

Estate planning for new parents isn’t just paperwork — it’s one of the most concrete acts of care you can take for your child. Before a baby, the stakes of dying without a will are real but often abstract. After a baby, they become immediate. Who raises your child if you and your partner both die? Where does the money come from? Who makes decisions if you’re in a coma?

Roughly 60% of American adults have no will or estate planning documents in place.¹ Among younger adults — the age group most likely to have young children — the share without a will climbs even higher: surveys consistently find that about 78% of millennials lack one.¹

These questions don’t have to be morbid. They have answers, and the right legal documents lock those answers in place so a court doesn’t have to guess.

The arrival of a child is consistently ranked by estate planning attorneys as the single most common trigger for people finally drafting their documents — and for good reason. But it’s also the life stage when many parents do it incompletely. They get a will but skip life insurance. Or they get life insurance but never update their beneficiaries to account for the new baby. Or they get everything done and then never revisit it as the family grows.

This guide covers the four documents every new parent needs and the practical steps to get them right.

Document 1: A Will — to Name a Guardian

The most important reason for a new parent to have a will isn’t the assets. It’s the guardian designation.

A guardian is the person who would raise your child if both parents died or were incapacitated before the child turns 18. In a will, you can name who that person is. Without a will, that decision falls to a family court judge who doesn’t know your family, your values, or your child.²

Courts generally try to place children with close relatives, but “close relative” and “the right person to raise my child” may not be the same. Your will is the only document that lets you make that call. When appointing a guardian, courts must act in the prospective ward’s best interests and may consider any relevant characteristics of the potential guardian, including finances, health, education, and relationship to the child.²

How to Choose a Guardian

Choosing a guardian is one of the hardest parts of estate planning for new parents, and many people delay completing their documents because they can’t agree or can’t decide. A few principles to help:

Think practically, not just sentimentally. The guardian you’d most want emotionally may not be the most practical choice. Consider age and health, where they live, whether they have children of their own and how your child would fit into that family, their values and approach to raising kids, and their financial stability. A guardian who needs to radically uproot their life to care for your child is in a harder position than one for whom it’s a manageable transition.

Have the conversation first. Designating someone as guardian without asking them is a mistake. The role carries real responsibilities, and the person you’re counting on should understand what they’re agreeing to.

Separate the guardian from the trustee. Your will can — and in many cases should — name different people as guardian of your child’s person and as trustee of your child’s money. A sibling who is wonderful with children may not be the best person to manage an investment portfolio. Splitting the roles provides a natural check on both.

Name a backup. Circumstances change. Name an alternate guardian in case your first choice is unable to serve when the time comes.

What Happens to the Money

Minor children cannot legally receive an outright inheritance — a court would appoint a property guardian to manage the funds, which involves ongoing court supervision until your child turns 18.³ At 18, the child receives everything at once, which is rarely a good outcome for a large sum.

A better approach is to include a children’s trust within your will. This keeps the funds under the management of a trustee you designate, who distributes money for education, healthcare, and support as needed, and can distribute the remainder at an age you set — 25 or 30 is common.

Document 2: Term Life Insurance — the Financial Foundation

A will tells the world who raises your child. Life insurance funds that upbringing.

If you have a child who depends on your income, and your death would create a financial hardship for that child, you need life insurance. For most new parents, term life insurance is the right product: it provides a death benefit for a defined period (commonly 20 or 30 years) at a relatively low cost. There’s no investment component and no complexity. You pay premiums, and if you die during the term, your beneficiaries receive the payout.

How Much Coverage Do You Need?

There’s no single right answer, but a common rule of thumb is 10 to 12 times your annual income.⁴ The logic: your family should be able to invest the death benefit conservatively and replace your income for many years without depleting the principal.

A more precise calculation factors in:

• Income replacement. How many years until your youngest child is financially independent? Multiply your annual income by that number as a baseline.
• Outstanding debts. Your mortgage, car loans, and other debts don’t disappear when you die. Factor in the payoff amounts.
• Childcare and household costs. If a stay-at-home parent dies, the surviving parent may need to pay for childcare they were previously providing. This cost is often underestimated.
• Education funding. If you intend to fund college, include an estimate in your coverage amount.
• Existing assets. Subtract savings, retirement accounts, and other assets the surviving spouse could draw on.

Both parents need coverage, even if one parent doesn’t work outside the home. The economic contribution of a non-employed parent — childcare, household management, scheduling, logistics — has real replacement value.

The Common Mistake: Having One Without the Other

One of the most frequent errors in estate planning for new parents is having a will but no life insurance, or life insurance but no will. These documents serve different functions and both are necessary.

A will without life insurance means you’ve named a guardian but given that person no financial support to do the job. A life insurance policy without a will means there’s money available but no one has legally established who raises the child or how the funds should be managed.

Another version of the same mistake: having life insurance but never updating the beneficiary designation. If your policy still names a parent or sibling as beneficiary from before the baby was born, that’s where the money goes — not to your child’s guardian or a trust for your child’s benefit. Review beneficiary designations every time your family situation changes.

Document 3: A Healthcare Proxy (Medical Power of Attorney)

A will and life insurance protect your child if you die. A healthcare proxy protects your family if you are incapacitated but not dead.

A healthcare proxy — also called a medical power of attorney or healthcare power of attorney — designates someone to make medical decisions on your behalf if you are unable to make them yourself.⁵ This might be a car accident, a serious surgery, a sudden illness, or any situation that renders you unable to communicate your wishes.

Without a healthcare proxy, medical providers follow their own protocols and state law, which typically prioritizes a spouse and then other close relatives. For married couples, this usually means the right person ends up making decisions, but there are gaps. If you and your spouse are both injured in the same accident, who speaks for you? If you are unmarried, do you want your parents making medical decisions, or your partner?

A healthcare proxy removes the ambiguity. Name the person you trust to make those decisions, and consider adding a brief living will or advance directive that articulates your wishes around life-sustaining treatment. Your healthcare proxy then has both the legal authority and the actual guidance they need.

Document 4: A Durable Power of Attorney

The fourth document every new parent needs is a durable power of attorney for financial matters.

This document authorizes someone — your agent — to manage your financial affairs if you are alive but incapacitated. Without it, even your spouse may face legal hurdles accessing certain accounts, managing property, filing taxes, or conducting business on your behalf.

“Durable” means the power persists if you become incapacitated, as opposed to a standard power of attorney that terminates when you lose capacity.⁶ For estate planning purposes, durable is what you want.

A durable power of attorney can be drafted as a general grant of authority (covering all financial matters) or limited to specific actions. For most new parents, a general durable power of attorney is appropriate. Name your spouse or partner as primary agent and a trusted backup in case your primary agent is also incapacitated.

Getting It Done: Practical Steps

The four documents — will, life insurance, healthcare proxy, and durable power of attorney — are connected. Doing two of the four is not a complete plan. Here’s how to approach getting everything in place.

Start with the will, healthcare proxy, and POA together. These three documents are often prepared as a package by an estate planning attorney. The cost for a straightforward package typically ranges from a few hundred to around a thousand dollars, depending on complexity and location. Online services like Trust & Will or LegalZoom offer lower-cost options for simple situations, though complex estates or blended families often benefit from working with an attorney directly.

Get life insurance quotes immediately. Term life insurance is priced largely on age and health. The younger and healthier you are, the lower your premiums. Delaying costs money over time. Most people can get quotes online in minutes and complete the application within a few weeks.

Coordinate your beneficiary designations. Your life insurance, 401(k), and IRA each have their own beneficiary designations that operate independently of your will.⁷ Review them and update them to align with your plan — typically naming your spouse as primary beneficiary and a trust for your children’s benefit as contingent beneficiary.

Put a calendar reminder to review every two to three years. A will drafted when you had a newborn may need updating when you have a second child, move to a different state, or experience a significant change in assets. Documents that are never updated eventually go stale.

The Bottom Line

Estate planning for new parents can feel overwhelming when you’re already managing a new baby, but the core of it is four documents that can be completed in a few weeks. A will names the guardian and directs your assets. Life insurance funds the future. A healthcare proxy and power of attorney protect your family if you’re incapacitated.

None of these documents are difficult to create. What requires thought is the decisions behind them — who raises your child, who manages the money, how much coverage you need. Make those decisions deliberately, put them in writing, and revisit them as your family grows.
