When a birth injury is diagnosed late, a potential claim depends on reconstructing events from records and expert opinion. A delayed diagnosis can affect how time limits are calculated in some jurisdictions, but it does not automatically extend them, so the timing needs prompt solicitor review.
Why diagnosis may be delayed
Some conditions only become apparent as a child misses developmental milestones, and clinicians may wait before confirming a diagnosis. Healthdirect notes that cerebral palsy, for example, has multiple possible causes and may not be diagnosed immediately. From a legal perspective, the key point is that a later diagnosis raises questions about when the connection to birth care could reasonably have been recognised.
Records
Time affects evidence. Staff move on, and records may be archived or stored in different systems. Requesting the complete set early is worthwhile. The OAIC explains access rights to health information, including differences between private providers and public hospitals.
- Antenatal and labour records, including monitoring traces.
- Neonatal and special care nursery notes.
- Child health records and early developmental checks.
- The diagnosis letter and investigations, such as imaging reports.
Expert assessment
Experts will consider whether care during pregnancy or birth fell below the standard of that time and whether the diagnosed condition is consistent with injury at birth or with another cause. Later investigations, such as imaging, may help with timing, but conclusions often remain contested. Independent review is usually needed before a family can understand whether a link is supportable.
Time-limit review
Some jurisdictions calculate time partly from when relevant facts were known or discoverable, while others rely more on age or fixed periods. NSW's limitation law is one starting point, but each state and territory differs. A solicitor will want the dates of first concern, diagnosis and any discussion suggesting the birth was relevant.
Adult claimants
Occasionally a person learns as an adult that their condition may relate to their birth. Adult claimants face similar evidence and limitation questions, often with older records. These issues are discussed further on the adult claims page.
For your next conversation
- What is the date on the formal diagnosis letter, and who issued it?
- When did a clinician first suggest the condition might relate to the birth?
- Do you hold the child's health record book and early developmental check notes?
- Have you requested records from every hospital and clinic involved, including transfers?
- Are any imaging reports or genetic test results available?
Common questions
Doctors said our son was fine at birth, but he was diagnosed at three. Why would they look back at the labour?
Some conditions are not obvious at birth and become clear as development is assessed. Experts may examine labour records to consider whether events then could explain the later diagnosis, or whether another cause is more likely. The records, not the birth-day impression alone, guide that assessment.
Does a late diagnosis mean time only starts running from that point?
Not necessarily. Some jurisdictions consider when relevant facts were known or discoverable, but rules differ and may include outer limits. A solicitor needs the specific dates to assess the position under the applicable law.
