Maria Shriver, who has split from husband Arnold Schwarzenegger amid a love-child scandal
, has hired a divorce lawyer, sources tell PEOPLE.
Prominent Los Angeles family law attorney Laura Wasser is now representing California's former first lady, according to sources close to Shriver.
"Maria hasn't decided yet if she wants to end her marriage," says one source. Wasser was hired before the news of the affair went public, sources say.
Shriver, 55, is separated
from the former governor, 63, who has admitted to fathering a child with another woman, reportedly a longtime housekeeper.
A Shriver rep had no comment.
