International Paternity & DNA Logistics

An over-the-counter kit won't establish paternity for a support case. Courts require a legal test with an unbroken chain of custody.

Chain of custody

Legal testing means verified identities, a witnessed collection, sealed samples, and documented custody — not a mailed kit. Arrange separate appointments in each country with independent collectors at clinics, hospitals, or embassy locations, who verify ID, photograph participants, and seal samples with barcodes for tracked courier shipment between authorized facilities only.

Consent and method

A legal custodian signs for a minor, and a court can compel testing with specific instructions. The standard is autosomal STR markers from cheek swabs, with a probability of paternity typically above 99.9%; if the alleged father is unavailable, close-relative testing (grandparents, siblings) is an alternative.

Documentation

Match names, dates, and document numbers across every form, get certified translations of foreign clinic documents, and budget several weeks for shipping, processing, and translation.
