She definitely sued the estate after Scott’s passing.
From an article:
More than three years ago, Jamie filed a claim against Scott's estate, saying he owed her $64,406. Jamie said she and Scott signed a prenuptial agreement before their 2013 wedding which provided that the musician would put $2,000 into a separate account each month that they were married, with a provision that the amount would increase by seven percent annually. But Jamie said Scott had only made two deposits by the time he died in December 2015.
