The number of people who die alone, without family or close friends by their side, is constantly increasing in France.
This phenomenon can be explained by a number of factors: social isolation, an ageing population, growing urbanisation, increased mobility, which is driving families further apart, and the shrinking size of households.
Changing lifestyles, with family ties sometimes weakened and social networks more restricted, also contribute to this worrying reality, raising major human and administrative issues.
There are many reasons why people may be looking for someone close to them. But before any investigation, it is necessary to check whether the person they are looking for is still alive. The services of a private detective, a professional in investigation and tracing, can be a considerable asset.
List of situations in which it may be necessary to check whether a person is dead and to request the assistance of a private detective:
- Search for biological parents (biological father or mother).
- Search for adoptive parents (father or mother).
- Search for an aunt or uncle.
- Search for grandparents.
- Search for cousins, half-brothers or half-sisters.
- Search for heirs.
- Search for the owner of abandoned property.
- Search for the owner of an abandoned plot of land.
- Search for a childhood sweetheart.
- Search for former classmates.
- Search for former work colleagues.
- Search for childhood friends.
- Searching for witnesses.
- Search for a person who has been missing for several years.
- Verification of the existence of a debtor for a debt collection procedure.
- Investigation to close a life insurance case (beneficiaries not found).
- Search for a person who has contracted a debt with an individual or a company.
- Verification of the death of a person for a pending estate.
- Verification of a person’s identity to prevent identity theft.
- Search for a tenant or former owner who has disappeared without leaving an address.
- Find a former patient for medical or administrative reasons.
- Find a person who has given evidence in a past court case.
- Search for an unknown relative mentioned in an official document (family record book, judgement).
What are the compulsory starting points for opening an inquest to check whether a person is dead?
There are two main situations when it comes to tracing a person who has died in France, and the investigation methodology varies according to the context.
- When the person’s civil status is complete and accurate: When civil status information (surname, first name, date and place of birth) is accurate and without error, the search is based on consulting official sources such as civil status registers, administrative databases or death notices published on the Internet.
- Cases where civil status is incomplete or approximate (most frequent in private investigations): In this situation, the investigations are more complex and require an in-depth analysis of the available information. The investigation may include reconstructing an identity from partial documents, interviewing witnesses, consulting archives (municipal, military, notarial, hospital) or even exploring specific databases to cross-check information and identify the person sought.
Each case requires a tailor-made approach based on the data available and administrative constraints.
Free search tools used by a private detective to find a deceased person
Private investigators have a number of resources at their disposal for tracing the whereabouts of a deceased person. The methodology is based on different stages and the use of specific tools.
First stage: generalist search engines
The first approach is to search on search engines such as Google for any digital traces of the person you are looking for. These might include obituaries, press articles, online genealogies or social networking sites.
Second stage: Death Match ID, an essential tool
The Death Match ID site is a valuable resource for private investigators and an excellent starting point for investigations. It is frequently consulted by clients before they contact an investigation firm.
The site is intuitive and accessible, and allows users to carry out searches by entering surname, first name, date and place of birth or death. An advanced search can also be used to refine the results by adding criteria such as gender or age at the time of death.
Why use ‘Décès Match ID’ to help find a deceased person?
- It helps to combat fraud, particularly when it comes to removing names from customer files.
- The data comes directly from INSEE.
- In March 2025, there were between 28 and 29 million recorded acts, covering deaths since 1970. However, the systematic computerisation of records only really began in the 1990s.
Limitations of the tool
Despite its effectiveness, some deaths may not be recorded, particularly in the following cases:
- Deaths that are too recent.
- Errors in INSEE databases.
- Confusion between birth name and married name.
- People who have died without an INSEE number.
Additional checks with town halls
When a place of birth or death is known, it is essential to contact the relevant town hall to obtain the corresponding civil status record. This helps to confirm the information and avoid any errors due to gaps in the online databases.
In this way, a rigorous investigation is based on a combination of digital sources and administrative investigations, guaranteeing reliable and accurate results.
Given the large number of searches for deceased people, private investigators play an essential role in tracing the whereabouts of unaccompanied individuals and identifying any relatives or beneficiaries.
Thanks to their investigative methods, they can locate heirs, resolve uncertainties about a death or provide answers to distant families looking for a long-lost relative.
A private investigator can also help to prevent estates from falling into disarray, by identifying the rightful beneficiaries of an estate. They provide invaluable assistance to notaries, lawyers and organisations faced with complex cases where the absence of relatives makes administrative procedures difficult.
Finally, calling in a private detective in these situations not only helps to re-establish broken family ties, but also provides a form of recognition for people who have disappeared into oblivion, by ensuring that their memory and their rights are respected.
