Concluding Observations, E/C.12/BGR/CO/4-5, 11 December 2012: Bulgaria
17. The Committee is concerned that couples in de facto unions and the status of children born as a result of those relationships are not regulated and protected by law. The Committee is also concerned that same-sex couples are not legally recognized and by the absence of a legal framework for the protection of the rights of such couples (arts. 2 and 10).
The Committee recommends that the State party undertake a comprehensive review of its legislation to ensure de jure equality between de facto and official unions, to legally recognize same-sex couples, to regulate the financial effects of such relationships, and to guarantee the full protection of the rights of children born out of wedlock.
