Under Vietnamese law single parents who are co-habiting cannot adopt.
International adoption official Tatiana Beams said: "This is a clear
contradiction of Vietnamese law, and such situations would not be allowed
for other couples.
"Most co-habiting couples who try to adopt as a single parent are either
turned away from agencies or face difficulties."
The US department dealing with the matter insists it abides by Vietnamese
rules when it comes to adopting from the country, but has not opposed
Angelina's action.

The 31-year-old star filed for adoption as a single parent, even though her
boyfriend, Brad Pitt, has become the adoptive father of her five-year-old
Cambodian son Maddox and two-year-old Ethiopian daughter Zahara.
The family, who also have a ten-month-old biological daughter Shiloh
together, live together in New Orleans.

A U.S. adoption agency representing the Hollywood star filed the

papers at Vietnam's International Adoption Agency, said Vu Duc

Long, the agency's director.

"She just filed the papers this week," Long said.

Jolie and Brad Pitt made a surprise visit to Ho Chi Minh City last November during which they also went to the orphanage to meet children there reports News Au.

Jolie said in December that she wanted more kids. "I'd like to add many more children and many more obstacles and many more things to my life," she told reporters while promoting her movie The Good Shepherd.
