Keith Schillings, of Schillings lawyers, said in a statement Monday that the celebrity couple had begun legal proceedings against the News of The World newspaper.
The newspaper reported Jan. 24 that Pitt and Jolie had agreed to divide their assets and made arrangements over the custody of their children.
Schillings, whose firm is representing the unmarried couple, said the report involved "false and intrusive allegations." He said the tabloid failed to meet a demand for a retraction and apology.
He also said Sorrell Trope, a divorce lawyer in Los Angeles, denied claims she had been in contact with the couple.
