Estate planning for new parents: the documents you need and why they cannot wait

7 min read · Updated June 7, 2026

Before a child, estate planning was a good idea. After a child, it is a responsibility — to the person who now depends on the choices you make today.

Why the stakes change with a child

Most people think of estate planning as something for older adults with accumulated wealth. But the most urgent reason to have an estate plan is not assets — it is dependents. If both parents were to pass before a child is grown, a court would decide who raises that child and how their inheritance is managed, with no guidance from the people who knew them best. A basic estate plan, done now, is the answer to that possibility.

Naming a guardian

This is the decision most new parents find hardest, and the one most worth making. A will lets you name a guardian for your minor children — the person or couple who would raise them if neither parent were alive. Without that designation in a will, a court decides. The court will try to act in the child's best interest, but it cannot know what you know about your family.

A few things to consider: name a primary guardian and an alternate, in case your first choice is unable or unwilling to serve. Discuss it with them before naming them — they deserve the chance to agree with open eyes. And if you and your partner disagree, take the time to resolve it: a will that contradicts a partner's will can complicate things enormously.

The will — and the trust for the children's inheritance

In a will you can also specify how your estate is to be managed for a minor child's benefit. Without explicit instructions, an inheritance left to a minor may pass to a court-supervised custodial arrangement until the child reaches the age of majority — which, in some states, means an eighteen-year-old receives a potentially large sum all at once.

Many new parents add a testamentary trust inside the will — instructions for a trustee to manage the inheritance over time, distributing for education, health, and reasonable needs, with the remainder at a later age. It costs little extra to add and offers significant protection.

Life insurance

A will manages what you have when you pass. Life insurance provides for what you do not yet have. For most young parents, this gap — between current assets and what would actually be needed to raise a child through adulthood — is substantial. Term life insurance is typically the simplest and least expensive way to bridge it. The beneficiary designation on the policy (not the will itself) determines where the proceeds go, so make sure it is named correctly.

Powers of attorney and healthcare directives

Estate planning is not only about what happens after you pass. A durable power of attorney names someone to manage your finances if you are incapacitated. A healthcare directive states your wishes for medical treatment, and a healthcare proxy names who speaks for you if you cannot. These documents protect your family in an emergency — not just after a death.

Beneficiary designations: the update most parents forget

Life insurance, retirement accounts, and payable-on-death accounts pass to named beneficiaries regardless of what the will says. When a child arrives, many parents forget to update these designations — or name the child directly, which can create its own complications for a minor. Review them now, and update them whenever something significant changes.

A letter of instruction for the people who would raise your child

Beyond the legal documents, consider writing a letter of instruction addressed to the guardian you have named. Not a legal document — a personal one. What matters to you in how your child is raised. Traditions, education, faith, extended family relationships. What you would want them to know about you. This letter has no legal weight; it has something more durable.

Getting started — and where to keep it

A basic estate plan for a new parent — will with guardianship, powers of attorney, healthcare directive, and updated beneficiary designations — is within reach with a licensed estate attorney, and should not take more than a few sessions to complete. Once done, the documents need a home. A secure vault like Legatus Vault keeps them encrypted during your life and releases them to the people you name when the time comes — so the guardian and executor you have chosen are handed exactly what they need, when they need it.
