Missing fathers on birth certificates

Missing fathers on birth certificates can have major consequences in inheritance disputes under the rules of intestacy.

A recent High Court case, Dorant v Dorant [2025], shows how unclear family records can complicate the administration of an estate.

The case involved:

• A £2 million estate in England & Wales
• A dispute over whether siblings were related by whole blood or half blood
• A birth certificate with no father named

Because intestacy rules can treat whole blood and half blood relatives differently, the missing information became central to the case.

The Court had to consider a wide range of evidence beyond official records, including:

• DNA evidence
• Marriage and immigration records
• Family witness testimony

Ultimately, the Court found the siblings were related by half blood, which affected how the estate was distributed.

Cases like this highlight an important point, that missing or incomplete family records can lead to delays, disputes, and costly litigation when someone dies without a will.

It’s a reminder of the importance of:

• Keeping records up to date
• Taking legal advice early
• Making a valid will wherever possible
