But Kris Jenner, Kardashian's mother, and several lawyers and managers are expected to testify about the pair's relationship and prenuptial agreement, according to a witness list filed Monday in Los Angeles.
Humphries is seeking an annulment of the pair's 72-day marriage, claiming it was based on fraud. Kardashian wants a judge to enter a divorce judgment instead and has denied accusations that she married Humphries for the sake of her reality shows.
She will testify that she "did not defraud (Humphries) into marrying her," the filing by Kardashian's legal team states.
Kardashian's boyfriend, Kanye West, and her sisters Kourtney and Khloe are not listed as probable witnesses.
Kardashian and West, who has been deposed in the case, are expecting a baby in July. Humphries' lawyers attempted to serve West a deposition subpoena disguised in a Nordstrom's box last year, just one of the incidents that have contributed to acrimony between Kardashian and Humphries since she filed for divorce in October 2011.
Humphries, a power forward for the Brooklyn Nets, and Kardashian were married at a lavish, star-studded ceremony that was televised by E! Entertainment Television. The network also airs "Keeping Up With the Kardashians" and several spinoff shows based on the family's activities.
Humphries' lawyers have not yet filed their witness list.
The former couple is scheduled to appear in a Los Angeles court on Friday to try to settle the case in advance of a May 6 trial date.
