Almost immediately after Dugard was found in August in Northern California, Slayton publicly announced he was her father and retained a lawyer to help him establish his paternity.
Dugard's mother, Terry Probyn, has never denied Slayton was the father. She said she told Slayton about the pregnancy and about his daughter's birth, but he showed no interest. He was also told by authorities when Dugard was kidnapped, the statement said.
"At no point did Mr. Slayton offer any assistance beyond what was requested of him while Jaycee was missing," the statement said. "It is now Jaycee Dugard's turn to express her feelings and she has no interest."
Slayton's attorney Gloria Allred said Wednesday that they will have no comment.
Last October, Slayton said he had never met Dugard because he did not know she existed until he briefly became a suspect in her 1991 kidnapping.
Outside of a court hearing regarding the suspects in Dugard's abduction, Slayton said he hoped to forge a relationship with Dugard. He said he attended the hearing for Phillip and Nancy Garrido, who have pleaded not guilty in the case, because "Jaycee Lee Dugard needs a father. She needs a masculine role model."
Dugard has been living privately in California with her mother and the two daughters she bore with Phillip Garrido while in captivity.
