DNA tests for family reunification

The most effective way to bring your family with you

The family reunification process is a legal procedure that allows non-European citizens, who meet the conditions set by the Ministry of Foreign Affairs, to initiate proceedings with the Spanish authorities to bring their relatives from their country of origin, with full guarantees. Article 53.b of the immigration law regulation.

Through this process, it is possible to request the reunification of different family members, such as the spouse or partner, parents, fathers-in-law or mothers-in-law, provided they are dependents, as well as children (whether natural or adopted). Each of these cases has specific requirements, for example, a marriage certificate or registration of the domestic partnership may be required in the case of spouses, or a birth certificate in the case of the reunification of parents or children.

In situations where this documentation is not available or in cases where more than a year has passed since birth and registration in the Civil Registry has not been carried out, the embassy/consulate may request a paternity/maternity test through a DNA analysis. This test is considered legally valid and allows unequivocally demonstrating the family relationship. It is a reliable way to establish the family bond in the absence of other necessary documents.

Citogen is part of the CNUFADN, the National Commission for the Forensic Use of DNA, and we are an accredited laboratory to perform this DNA test. Additionally, we will assist you in the procedures with the embassy/consulate and send the report with the result.

How does a family reunification process work through genetic testing?

To apply for the reunification in Spain of your relatives from their country of origin, you must provide proof of kinship to demonstrate your family link. If you do not have a legally valid document for this, a DNA test can serve as proof. To do this, the following steps must be followed:

The steps to follow are:


Contact the Spanish embassy/consulate

Contact the Spanish embassy/consulate in the country of origin to carry out the family reunification procedures.


The embassy/consulate will reply

The consular office will respond, if the application is valid, offering the possibility of carrying out a DNA test to prove the family link. They will send an official communication.


send official communication and request budget

With that information in your possession, fill out the form below attaching the official communication sent by the consular office. With this request, our technicians, as laboratory personnel authorized by the Ministry of Foreign Affairs and Cooperation (MAEC), will prepare a budget for the genetic study, which will be sent to you via email for your confirmation and payment.

DNA Test Form



After reviewing your case, you will receive an email with the budget for the genetic study and a link to pay it directly.


Sample Collection

Once the payment is received, we will proceed with the sample collection:

  1. We will contact the embassy to schedule an appointment for the relatives in the country of origin and inform them about this appointment at their facilities.
  2. We will give an appointment to the person seeking family reunification in Spain to take their sample in an approved laboratory (as close to their home as possible); we have laboratories in many parts of the peninsula, Balearic Islands, and Canary Islands.


Conducting the Study

Once we receive all the samples, we will carry out the requested study in our laboratory to determine the kinship relationship requested by the embassy.


Report of Results

The results report will be sent directly to the Spanish consular office, which will incorporate it into the family reunification application.

A copy of the report will also be sent to the applicant for reunification, and it will be the Embassy or consular office who, once the information has been analyzed, will contact the applicants to give them the conclusion of their family reunification request.
