A federal employee said she was divorced but kept her ex-husband and his two children on her federal health insurance policy. An investigator found that a divorce decree submitted by the employee was not issued by a court. She was fired and appealed her case to a federal court.
When the former wife of a retired federal employee was given 53% of his monthly annuity payment, the retired fed was unhappy with OPM so he appealed to MSPB and then to a federal court. After all the litigation: the federal retiree gets less than his former wife.
Divorce can be expensive. This retired federal employee not only gave part of his annuity to his former wife, he also got notified by OPM that he had not been paying enough and that he also owed her more than $24,000 in additional money.
A former spouse of a federal employee may get a substantially larger annuity when the former fed dies. Here is one case that shows how it can happen.
