What is the Family Book and why has it changed forever?

Traditionally, the Family Book was a physical document, similar to a small blue passport, that was issued at the time of marriage or when registering the first child if there was no prior union. Its function was clear: to certify the kinship relationship between spouses, and between parents and children.

However, we are in 2026 and Spanish bureaucracy has completed its digital transition. The final entry into force of Law 20/2011 of the Civil Registry meant the end of the printing of new physical books. Now, each citizen has an individual record and a unique personal code that brings together all their civil events from the birth of a child to possible changes in marital status.

Important:

Family books issued before 2021 remain fully valid to prove family ties. However, they are no longer physically updated. Any new change must be proven through digital birth or marriage certificates.

What is the Family Book for today?

Although the format has changed, its usefulness remains fundamental for your daily life.

DNI for Minors

It is the base document to prove filiation when obtaining the first DNI for your children.

Social Security

Necessary to register children as beneficiaries on the health card or to request maternity/paternity benefits.

School Enrollment

Proves the family unit and points for siblings in the admission processes of educational centers.

Travel with Minors

If you travel abroad with your children and they do not have their own passport, the Family Book (or the Literal Birth Certificate) is vital to prove that you are the legal guardian to border authorities.

How to obtain your Digital Family Record

Transition to the Unique Civil Registry: A Paradigm Shift

Formerly, the Civil Registry functioned through physical "volumes" and "folios" distributed in each local court. This made requesting a duplicate or an update a slow process that often required physical travel.

With the full implementation of Law 20/2011, Spain has moved to an Individual Registry model. What does this mean?

  • Personal Code: Each person is assigned a unique code at their first registration (birth).
  • Unique Sheet: All the events of your civil life (marriage, divorce, nationality) are recorded chronologically in your personal record.
  • Interoperability: The Tax Office, Social Security, and the General Directorate of Police can consult your family data without you having to carry the physical book in your hand.

What if I lose my old Family Book?

If you have lost your physical book issued before 2021, do not panic. Nowadays, duplicates of the traditional blue book are no longer issued. Instead, the Civil Registry will issue you a series of literal certificates that prove exactly the same information.

Request a Literal Marriage Certificate.

Request Literal Birth Certificates for each of your children.

These documents are free and have a digital authenticity seal.

Note: For cases of divorce or separation, the original book usually stays with the parent who has custody of the children, but the other parent can request their own literal certificates at any time.
