This paper aims at highlighting and analyzing questions upon homoparental families composed by two women who opted for mothering, taking advantages of the latest reproductive technologies with or without the recording of double motherhood. The discussion on lesbian families underscores some aspects of the family- building process from the motherhood desire to daily family routine. This issue brings into question the possibility those families reproduce the traditional heterosexual pattern. To accomplish this, nine women ranged between 33 and 45 years old, living in Rio de Janeiro, participated in this research. It pointed out that most of the lesbian couples interviewed wanted biological children to be raised by themselves without any interference else. The legalization of the emotional tie between the biological mother s partner and the child was possible in some cases through the unilateral adoption, promoting double motherhood. Some families that have not legitimated their situation have continued legally unprotected. It is proved, in some cases, that the unilateral adoption promotes emotional link among the biological mother, the co-mother and the child. In some cases, biological grandparents accept the children as their natural grandchildren. Even though some juridical and social rights have been conquered by homoparental families just because of the reproduction of a heterosexual pattern, the achievements engender conditions in which other family models may be recognized rather than only create new hierarchical family systems.
