Buffington filed for divorce from Quaid in March 2012. Buffington's attorney then withdrew the divorce papers on April 26, 2012. In the summer of 2012, Quaid and Buffington moved to California. In October 2012, Quaid and Buffington again decided to separate, and Buffington filed for legal separation, seeking joint legal and sole physical custody of the twins. After waiting to establish the required six months of residency in California, Quaid filed for divorce on November 30, 2012, asking for joint legal and physical custody of the children and offering to pay spousal support to Buffington. They then reconciled and the divorce was dismissed by September 2013. On June 28, 2016, the couple announced in a joint statement that they were divorcing, with Kimberly asking for full physical custody and joint legal custody. The divorce was finalized on April 27, 2018.
