How old is you son? Has he been diagnosed with anything? On any medications for anything?
I feel the age and diagnoses would help others give suggestions or perhaps insight.
Unwanted behaviors can be common during a divorce, however, sometimes there can be a medical reason behind this that you will want to address. Something triggered by the stress of the changes in your home. Don't chalk it up to entire rebellion over the divorce. It is a good thing that you are trying to understand why these behaviors are happening.
Are you kids going through any counselling for this major change in their life?
