Remarriage

My mother in law is remarrying. Am I allowed to go to the chuppa

Shalom!

Thank you for your question

It is completely permitted for you to attend your mother in law’s remarriage.

That being said, the custom is for children not to attend the wedding of a parent, However, if one's parents insist, then one should attend the meal and not the chuppah. In a case that one's parents want them to attend the chuppah as well, then there is no prohibition for them to attend.

Although there is no clear source for this custom, it appears that the custom (in a case of divorce) developed because as long as their mother has not remarried, there is still the hope and possibility that she will remarry their father, her former husband. However, once she marries another man she becomes permanently forbidden to her former husband. Therefore, perhaps it became felt that it is not appropriate for children to take part in an event that permanently prohibits their parents from possible reconciliation.

Another reason for children not to attend their mother’s remarriage is because once she remarries, the children become obligated to show honor to her new husband (YD 240:21). It is not appropriate for children to attend an event that compels them to increase in their obligation of honoring “parents,” extending it from their father to now having to include their new stepfather.
