Unfortunately court can bring emotions to the fore, and parties, sometimes feeling aggrieved, resort to unseemly means to prevent what is perceived as a potentially unfair result or simply to educate the world. If the victim knows how to respond, the consequences will be severe.  Be aware:

1. That court is not interested in mud slinging, and often takes a dim view of the purveyor
2. Society has become accustomed to mud raking, and generally – unless it involves famous celebrities – tune out
3. Separately, blackmail and attempting to obstruct court process are serious offences
4. The manner in which evidence has been obtained may be illegal. even emails possessed of a partners activities may result in imprisonment.
5. If as as result of mud slinging, especially if brought to the attention of an employer,  one spouse loses financial income, there will be a re-balancing of spousal support calculations, and separately potential civil action.
6. There are legitimate reasons for whistle blowing, though even then as Julian Assange has found, there can be a serious sting in the tale. Motivation prompted by divorce is rarely one of them.
