After an unusual divorce filing, officials in St. Johns County, Florida, have launched a criminal investigation and placed a woman in jail on perjury charges, the St. Augustine Record reports.

Sherril Thurston divorced her husband Bob, who has since passed away, in 2009. According to the news source, the divorce paperwork was filed in Florida where Bob Thurston owned property. However, Bob’s daughter, Tracie, has contended that her father and step-mother in fact lived in North Carolina when the divorce was filed. Florida law requires that one spouse be a resident of the state for at least six months before a divorce can be filed.

The separation of the couple is even more complicated, however, because Bob Thurston was suffering from dementia, meaning he may not have had the capacity to truly understand the consequences of the divorce.

According to a family law attorney in Zephyrillis, Florida, lawyers are seeing an increasing number of baby boomers looking to dissolve marriages of 30-plus years. This could be due to the lessening stigma regarding divorce for adults over 50 and the freedom couples feel once their children have grown up and moved out. As a result, child custody and support are no longer an issue. However, health issues that come with age can further complicate divorces.
