The statement, which carries her signature and was signed under penalty of perjury, was submitted in federal court on Monday.
It echoes past public statements that Clinton has made in the last few months regarding her private email account.
In the statement, she also declares that 55,000 pages of emails were turned over to the State Department last December.
The declaration was made as part of a lawsuit filed by the conservative group Judicial Watch, which had sued for records related to Clinton's tenure as secretary of state.
