CCQ-1991 - Civil Code of Québec

Full text
541.20. The filiation of the child is established in accordance with the rules of filiation by acknowledgement or by blood. However, the presumption with regard to the spouse of the woman or person who gave birth to the child does not apply. Furthermore, no bond of filiation may be established with regard to the person who has agreed to provide their reproductive material as a third person for the purposes of the parental project.
Only the court is then authorized to change the filiation. An application to that effect must be submitted to the court within 60 days after the birth of the child, except in exceptional circumstances.
