Finland's Parliament on Wednesday approved a citizens' initiative to recognise both women in same-sex partnerships as mothers from the moment their child is born.
The proposed change to the Maternity Act applies to same-sex partnerships where one of the women undergoes fertility treatment to become pregnant.
At the moment, the woman not giving birth must adopt the child in order to gain legal rights as a parent. Proponents of the new law have called this process slow, expensive and humiliating.
122 MPs voted for the proposal and 42 against. The Christian Democrats were the only party that unanimously opposed the law, that is expected to go into effect next spring.
This is the second citizens' initiative that has been approved by Parliament. The first allowed same-sex couples to marry.
