538.2. The contribution of genetic material for the purposes of a third-party parental project does not create any bond of filiation between the contributor and the child born of the parental project.
However, if the genetic material is provided by way of sexual intercourse, a bond of filiation may be established, in the year following the birth, between the contributor and the child. During that period, the spouse of the woman who gave birth to the child may not invoke possession of status consistent with the act of birth in order to oppose the application for establishment of the filiation.
