A notary in the Brazilian state of Sao Paulo has sparked controversy by accepting a civil union between three people.
Public Notary Claudia do Nascimento Domingues has said the man and two women should be entitled to family rights.
She says there is nothing in law to prevent such an arrangement.
But the move has angered some religious groups, while one lawyer described it as "absurd and totally illegal".
The three individuals, who have declined to speak to the press, have lived in Rio de Janeiro together for three years and share bills and other expenses.
Ms Domingues says they have already opened a joint bank account, which is also not prohibited by any law.
