During a divorce, spouses tend not to be on very good terms with each other, which is not unexpected given the circumstance. For most, much of the communication can be directed through their attorneys. If they have children, there may be some additional forced contact, during hand-offs with their child or children, but even there, their attorney can help them develop a routine to reduce the likely hood of conflict.
When a couple divorces, they may have a great many things on their mind. Bitterness, frustration or other emotional upset over the ending of their marriage. Financial worries, with concerns over what their economic condition will look like after the divorce. If they have children, the details of their child custody arrangements, if they will receive or pay child support and how to deal with separate households with their kids.
Modern physics teaches that the presence of an observer potentially changes the outcome of an experiment. Some seem to feel that a similar situation exists with regard to the potential for divorce. There is a view that believes that if you think about divorce, discuss it with your spouse or friends that it will, like a contagion, begin to spread and that you will then have an urge to file one of your own.
