# New baby paperwork checklist

Between the feedings there's a stack of forms: the birth certificate, the Social Security number, the health plan, and the documents most parents put off, like a will that names a guardian. Here's the list in the order it comes up.

**Quick answer.** At the hospital, say yes to the Social Security number on the birth certificate form. In the first month, add the baby to your health plan within its deadline and order certified birth certificates. In the first year, make a will that names a guardian, review life insurance, and update beneficiaries.

## At the hospital

- **Birth certificate application**: the hospital helps you complete it. Check every spelling before you sign.
- **Social Security number**: the Social Security Administration says the easiest way is to say yes on that same form; it asks for both parents' numbers, but you can apply without them ([SSA](https://ssa.gov/pubs/EN-05-10023.pdf)). The card arrives by mail after SSA verifies the record.

## The first month

- **Health insurance**: a birth usually opens a special enrollment window to add the baby; check your plan's deadline, which is often short.
- **Certified birth certificates**: order a few. Passports, school enrollment and benefits each want one.
- **Employer paperwork**: leave forms, dependent care accounts and a new Form W-4 if your withholding should change.

## The first year

- **A will that names a guardian**, so a court isn't left to choose who raises your child. See [will witness requirements by state](/notary/will-witness-requirements-by-state) for how it's signed.
- **Powers of attorney and health care directives** for each parent, so the other can act if one is hospitalized. See [power of attorney requirements by state](/notary/power-of-attorney-requirements-by-state).
- **Life insurance and beneficiaries** on retirement accounts and policies; ask an agent how to name a minor child.
- **A passport** if you'll travel; both parents usually need to consent for a child under 16.
- **College savings**, if you plan to start an account.

## At tax time

Keep the Social Security card, childcare receipts with the provider's tax ID, and medical bills in one folder. They support the child-related credits and any dependent care account claims.

## Questions

**How do we get the baby's Social Security number?**

The Social Security Administration says the easiest way is to say yes when the hospital asks on the birth certificate application. It asks for both parents' numbers, but you can still apply without them. The card is mailed once SSA has verified the information.

**What if we didn't apply at the hospital?**

You can start online at ssa.gov/number-card and finish at an office, or use Form SS-5. SSA asks for original proof of the child's citizenship, age and identity, and proof of your identity and relationship to the child, and warns of delays while the birth record is checked.

**Do we really need a will now?**

A will is where most parents name who would raise their children if both parents died. Without one, a court decides. It's the single most common reason new parents make their first will.

**Does the will need a notary?**

It depends on the state. Many states use a notarized self-proving affidavit so the witnesses don't have to be found later. Our will witness requirements by state table shows each state's rule.

**What about life insurance?**

Many parents look at term life insurance so a child's needs would be covered. Name the beneficiary carefully: naming a minor child directly can mean a court-supervised account, which is a question for an insurance agent or lawyer.
