Search for origins: International conventions and the Swiss Civil Code recognise the right of adopted persons to know their origins. The Terre des hommes Origin Research/Adoption service makes its archives available and offers support in this process, whether to understand the historical issues of the country of origin or to find the biological family with the help of its network. We invite you to contact us at the following e-mail address: adoption@tdh.ch or to contact us by phone + 41 58 611 06 66 (Wednesday only).
