Polanski's lawyer Harland Braun told the BBC: "She is coming with her husband because she is exhausted of this case going on for 40 years".
Geimer, who has three sons, has said in the past that she has forgiven Polanski.
Gordon said he would issue a written ruling on the motion. "It's about equity and consideration", she said, reading from a prepared statement.
LOS ANGELES (AP) - Roman Polanski won't take his chances to return to court to resolve his sexual-assault case, so his victim is going to stand up for him.
Geimer's testimony marked the first time she has appeared in court in the drawn-out case involving the 83-year-old Oscar-winning filmmaker, who fled to his native France in 1978 and has been engaged in a legal battle to avoid further jail time if he returns to the United States.
She said she is now a grandmother and wants to end the media intrusion that she believes exists because the case is not settled.
He was unable to up his 2002 best director Oscar for The Pianist because he feared arrest if he returned to the US.
Polanksi's attorney, Harland Braun, asked the judge on Friday to unseal testimony about the 1977 plea deal.
Samantha Geimer was just 13 when she was raped by Polanski at a Hollywood party, and he subsequently pleaded guilty to having unlawful sex with a minor, but left America and fled to his home in France on the eve of sentencing in 1978.
Panama switches diplomatic recognition from Taiwan to China
Panama's moves leaves Taiwan with only 20 diplomatic allies in the world, mainly small nations in Latin America and the Caribbean. Taiwan's government said it would not compete with China in what it described as a "diplomatic money game".
He admitted statutory rape after a number of more serious charges were dropped, and spent 48 days in custody to undergo psychiatric evaluation before being released. The trial judge in the case found "substantial evidence of oppressive conduct by Polanski and a strong likelihood that a jury would find despicable conduct on the part of Polanski".
Braun wants to use the transcript to show Polanski has served his time so the global warrant is dropped.
The defense lawyer has maintained that Polanski has already served more than enough time, including time he spent at a state prison in Chino in the late 1970s for a pre-sentencing diagnostic examination and also in jail and under house arrest in Switzerland in 2009 as Swiss authorities considered an extradition request.
In April, Gordon rejected Polanski's latest effort to be tried in absentia, ruling that Polanski must first return to the US and submit to the court's jurisdiction before the case can be resolved.
Geimer sued Polanski and reached a settlement in 1993 for $500,000 that included over $100,000 in interest payments, according to the Associated Press.
While most sex abuse victims are criticizing the government for stronger sentencing in an effort to curb the number of incidents and to feel vindicated in their specific cases, Geimer is taking the opposite approach.
She wrote a memoir titled "The Girl: A Life in the Shadow of Roman Polanski" four years ago.
The most recent attempt to resolve matters ended in April, when a Los Angeles judge ruled that the French-Polish director could not cut a deal from overseas to return to the USA without serving more jail time.
