Is a divorce valid if a man's parents forced him to pronounce it due to their disagreements with his wife, even though there are no disagreements between the spouses themselves?

It appears that "compulsion" here refers to the parents pressuring their son to divorce his wife. The preponderant opinion is that it is not obligatory to obey them in this divorce. However, if the husband divorces his wife to please his parents, his divorce is valid. The parents' pressure is not considered a legitimate duress that would invalidate the divorce.
