The single hardest call we field on NEC intake is from a parent who has just learned the deadline already passed. Their baby was diagnosed with necrotizing enterocolitis years earlier, they didn't know about the lawsuits, and by the time they found us the calendar had run out. That call should never have to happen. Here is what every family needs to know about NEC filing deadlines, written so you can read it on your phone in the NICU waiting room.
The Short Answer
The deadline for filing an NEC lawsuit depends on three things: the state where the case will be filed, whether the lawsuit is brought on behalf of a surviving child or as a wrongful death claim, and whether your state's law starts the clock at the date of diagnosis or at a later "discovery" date. For surviving children, most states give the family until well after the child turns 18 to file — minors get extra protection. For wrongful death cases, the deadline is typically much shorter and starts running from the date of death, not the date of diagnosis.
Both kinds of cases benefit enormously from being filed sooner rather than later, even if the deadline is years away. Evidence gets stale, records get lost, witnesses move on.
Why Statutes of Limitations Are Different for Children
In most states, the statute of limitations for a personal injury claim brought on behalf of a child is "tolled" — meaning paused — while the child is a minor. The clock doesn't start running until the child turns 18 (in most states) or sometimes later. After that, the standard personal injury limitations period of two to four years begins.
That means a child who developed NEC as a premature infant in 2018 often still has a viable claim in 2026 and beyond, depending on the state. This rule exists because the law recognizes that infants and children cannot bring lawsuits themselves, and parents may not learn about the legal claim until much later.
Minor tolling does not always apply, and it never extends a wrongful death claim. Important exceptions:
- Statutes of repose. Some states have an absolute deadline that cuts off product liability cases at a fixed number of years after the product was sold, regardless of the child's age.
- Parents' separate claims. Parents have their own claims (medical expenses, emotional distress) that may be subject to the standard adult statute of limitations and start running earlier.
- Wrongful death. If the child died from NEC, the case becomes a wrongful death claim on behalf of the family, which has its own deadline measured from the date of death.
Plain language: "Tolling" means the clock is paused. While the child is a minor, the lawsuit clock generally pauses. After they turn 18, the regular two-to-four-year clock starts running.
The General Pattern Across States
Statutes vary, but the general pattern looks like this:
Surviving Children (Standard Product Liability)
- 2-year states: California, Texas, Pennsylvania, Illinois (among others). Two years after the child turns 18 in most cases.
- 3-year states: New York, North Carolina, Maryland, Washington (among others).
- 4-year states: Florida, Nevada, Utah (among others). Florida specifically gives four years from accrual, with strong minor tolling.
Wrongful Death (When NEC Was Fatal)
- 1-year states: Louisiana, Tennessee, Kentucky.
- 2-year states: Most others, including California, Texas, Florida, Illinois, and Pennsylvania.
- 3-year states: New York, Massachusetts.
These deadlines run from the date of death, not from the date of diagnosis. They are not extended by the child's age. Wrongful death deadlines are the ones we worry about most.
Statutes of Repose
A handful of states impose an absolute outer cap on product liability claims regardless of any tolling rule:
- Texas: 15 years from the sale of the product.
- North Carolina: 12 years.
- Indiana, Connecticut, Tennessee: 10 years.
Because NEC litigation centers on Similac and Enfamil formula sold to NICUs, the date of "sale" of that formula is usually within weeks of the NICU stay itself — meaning these repose periods can be the operative deadline for older cases.
The Discovery Rule
The "discovery rule" is a legal doctrine recognized in many states that starts the clock not at the date of diagnosis, but at the date when the family knew, or reasonably should have known, that the diagnosis was connected to the formula. For families who learned about the NEC litigation years after their child's diagnosis, the discovery rule can be the difference between a viable case and a barred one.
States that recognize the discovery rule in product liability cases include California, Florida, New York, Illinois, and many others. The rule is not automatic — we have to plead and prove that the connection was not reasonably discoverable earlier.
Why You Should Not Wait Even If Your Deadline Is Years Out
Three reasons:
- NICU records are time-sensitive. Hospital records retention policies vary, and some institutions begin discarding paper charts and microfilm older than a set number of years. The longer we wait, the harder it gets to prove what formula was used.
- NICU staff turnover. Nurses and neonatologists move, retire, or pass away. The witnesses who can testify about what was fed to your baby in 2014 are not necessarily reachable in 2032.
- The litigation is moving. The federal NEC MDL (MDL 3026) has bellwether trials scheduled for August 2026, November 2026, and February 2027. Filing now positions a case to benefit from those rulings.
What to Do This Week
If your premature baby was diagnosed with NEC after being fed Similac or Enfamil in the NICU, take three steps this week:
- Locate the NICU discharge summary. It usually identifies the formula used and the NEC diagnosis. The hospital's medical records department is required to provide a copy.
- Write down the timeline. Birth date, gestational age, NICU admission, when formula was started, when NEC was diagnosed, surgeries, complications, current status.
- Schedule a free case review. Tell us the state you live in and the state where the NICU care happened. They are sometimes different, and that affects the deadline analysis.

The Bottom Line
NEC filing deadlines are state-specific, fact-specific, and unforgiving. Minor tolling helps surviving children. Wrongful death deadlines are shorter and start at the date of death. Statutes of repose can override everything else in a small number of states. The discovery rule may extend the deadline in many states if the family did not know about the formula link until later.
