In divorce documents obtained by ET, Cavallari lists the date of separation as April 7, citing "marital misconduct" and "irreconcilable differences" as the reason for the breakup.
Cavallari claims in her legal docs (filed on April 24 in Tennessee) that Cutler "is guilty of such inappropriate marital conduct as renders further cohabitation unsafe and improper," adding that "any misconduct alleged or implied against her in the complaint for divorce was in response to and/or as a result of misconduct on behalf of the Husband."
Cutler officially filed for divorce on April 21, citing "irreconcilable differences" and listing the date of separation as April 21. He did not mention any misconduct against Cavallari in his petition.
As for their kids -- Camden, 7, Jaxon, 5, and Saylor, 4 -- Cavallari is asking for primary physical custody and seeking child support. She's requesting that Cutler be allowed visitation, and that the former NFL star pays for their children's health insurance and maintains a life insurance policy with her name listed as the sole beneficiary.
Cutler is requesting joint custody of their children and equitable distribution of the marital assets, stating that he has always been "the available at home parent and primary caretaker of the parties' minor children."
Cavallari denied Cutler's claim in her filing, alleging that she has been "the primary residential parent" and that she is "a fit and proper person to be named Primary Residential Parent."
The court docs also reveal that a temporary restraining order was filed, which is said to be a standard in divorces in the state of Tennessee. The restraining order prevents Cutler and Cavallari from disposing or concealing marital property, harassing each other and relocating the children.
