DNA Testing Requirements

When Norwegian authorities may require DNA testing

In cross-border family cases, Norwegian authorities may request DNA testing to document biological relationships—most commonly in immigration cases where family ties must be proven with reasonable certainty. DNA testing is also frequently discussed in cross-border surrogacy cases, but DNA evidence is not the same as legal parenthood.

Legal basis

• Immigration Act (Utlendingsloven) § 87 allows DNA testing when it is necessary to establish a family relationship and other information is insufficient.
• UDI guidelines (UDI 2010-035) describe how and when DNA testing is used in practice, including information duties and case processing routines.

What a DNA test can (and cannot) prove

• It can prove biological relatedness (e.g., parent–child relationship).
• It does not automatically create legal parenthood under Norwegian family law. Legal parenthood depends on parentage rules, registrations, and in some cases court/adoption processes.

Typical situations where DNA testing comes up

• Family immigration where birth documentation is missing, unreliable, or contested.
• Refugee family reunification where documents are difficult to obtain.
• Cross-border parentage questions, including some surrogacy and assisted reproduction contexts.

Process (high-level)

Procedures vary by country and case type, but the general pattern is:

1. UDI (or the police/embassy on UDI’s instruction) informs the parties that DNA testing is required or offered.
2. Samples are taken under controlled conditions (chain-of-custody) to protect integrity.
3. Results are sent back through official channels and become part of the case file.

Refusing DNA testing without a good reason can negatively affect the application outcome.

Do Better Norge perspective

• Transparency: applicants deserve clear explanations of why DNA testing is requested and how results will be used.
• Proportionality: DNA testing should be used only when necessary—after documents and other evidence are assessed.
• Child rights: delays in family cases can harm children; authorities should process DNA-related steps efficiently.
