Should You Update Your Will Right After Your Baby Is Born?

By The Penny Plan Editorial Team Published July 13, 2026 6 min read

The nursery is barely finished and there’s already a mental list forming: pediatrician, car seat, sleep schedule, and somewhere near the bottom in smaller letters, “update the will.” It’s the kind of task that feels urgent and impossible to get to in the same breath, especially in the fog of a newborn’s first weeks.

At a glance

There’s no legal deadline tied to a baby’s birth that forces a will to be updated by a certain date. That said, a new baby is one of the most common reasons people write a will for the first time or revise an old one, mainly because guardianship suddenly becomes a real question instead of a hypothetical one. Whether to handle it in the first weeks or the first year is a matter of personal weighing, not a fixed rule.

Why guardianship changes the calculation

Before a child exists, a will mostly deals with property and who inherits what. Once a child is born, it can also name a guardian — the person who would raise that child if both parents became unable to. This is often the single biggest reason new parents who never bothered with a will before suddenly feel the pull to write one. Without a named guardian on record, the decision falls to a court, which typically weighs state law, any surviving relatives, and the child’s existing relationships rather than a preference the parents never wrote down.

Why the timing feels harder right after birth

Sleep deprivation, physical recovery, and an unpredictable schedule make sitting down to think through worst-case scenarios feel almost cruel timing. Some parents find that drafting something quickly, even a simple version, brings a sense of control back into a chaotic stretch. Others deliberately wait a few months until the initial adjustment period settles, reasoning that a rushed document isn’t necessarily a better one. Both approaches are common, and neither is wrong — what matters more is not letting “later” quietly turn into “never.”

The practical steps people often miss

Worth remembering

There’s no single right week to have this done, and treating it as an all-or-nothing task tends to backfire — it either gets rushed under pressure or postponed indefinitely out of guilt. What tends to work better is starting with the guardian decision, since that’s the piece with no automatic fallback, and building the rest of the plan — trusts, executors, a reserve like an emergency fund that a guardian could draw on — around it as time allows.
