The "Scream 2" actress filed for divorce from the 46-year-old "Grey's Anatomy" star in February 2016, after 14 years of marriage. But according to court documents obtained by Entertainment Tonight, she has received a third warning from the court urging her to submit the judgement to the court, or request a dismissal.
"If you fail to take the appropriate steps in your case, the court may dismiss your case for delay in prosecution," the documents reportedly explained.
Gayheart, 47, is required to submit several disclosure forms and judgement documents to finalise her divorce.
The mother of two asked for spousal support, as well as joint legal and physical custody of the couple's two young daughters, Billie, nine, and Georgia, seven.
Dane confirmed their divorce in a statement, telling People: "After 14 years together we have decided that ending our marriage is the best decision for our family."
"We will continue our friendship and work as a team to co-parent our two beautiful girls as they are the most important thing in the world to us."
