Lisa Marie Presley’s young children are reportedly barred from traveling to Memphis, Tennessee, to celebrate their grandfather Elvis Presley’s 85th birthday celebration.

According to The Blast, the musician’s estranged husband, Michael Lockwood, is not allowing their 11-year-old twin daughters, Harper and Finley, to travel for the celebration. Under Lisa Marie, 51, and Lockwood’s current custody agreement, the kids cannot travel outside of California without the consent of both of their parents or approval from the court.

In an effort to overrule Lockwood’s decision, Lisa Marie’s legal team from Brot Gross Fishbein appeared in Los Angeles County Court on Tuesday (the day before the festivities were scheduled to start) to file emergency documents asking a judge to allow the children to travel.

The Blast reports that the judge ultimately denied her ex-parte request in the case, saying that the situation did not rise to the level of an “emergency.”

Though Lisa Marie and Lockwood, 58, share joint legal custody of the twins, a source tells PEOPLE that Lockwood only has supervised visits with the girls three times a week while Lisa Marie has physical custody. According to the source, Lockwood also blocked the girls from traveling to Memphis in August for “Elvis Week,” which was a celebration commemorating the 42nd anniversary of Elvis’ death.

Representatives for Lisa Marie and Lockwood did not immediately respond to PEOPLE’s request for comment.

Elvis’ birthday celebration is being held over the course of four days at the rock and roll legend’s famous Graceland mansion starting on Wednesday. The Graceland website says that events this year include the annual “Elvis Birthday Proclamation Ceremony,” private tours of Graceland with Elvis’ ex-wife (and Lisa Marie’s mother) Priscilla Presley and a “Birthday Celebration Concert” featuring Terry Mike Jeffrey and the Memphis Symphony Orchestra.

Lisa Marie married Lockwood, her fourth husband, in 2006 and filed for divorce in June 2016. Ever since their separation, the two have been embroiled in an ongoing custody battle. They are set to go to trial over custody, visitation rights and child support amounts on July 20, 2020.
