In the United States, engagement has no legal consequences, so there are no restrictions against the practice while involved in a divorce. However, the action has the potential to interfere with the divorce proceedings and is not always wise, according to Feinberg, Mindel, Brandt & Klein, LLP.
Divorce is an emotional trauma, and a new engagement has the potential of worsening the emotional state of one or both parties. If there are children, the parent who isn't engaged often becomes less willing to work through visitation and custody issues. The engagement tends to increase friction between the divorcing parties. Engagement before working through the emotional turmoil of dissolving a marriage also has the potential to affect the new relationship.
