Two questions: If he withheld this information at a conference and proof is found would criminal charges also be able to be filed? Secondly--if I failed to take action after I received his notice (that he had another job) and we went to court a year later what retroactive change would he be liable for--just from the time he did not disclose his income until he disclosed it (gave me notice)? Or could I could back from the date I filed to when he started?
