How to seat divorced parents at the reception dinner

Can he sit with his family and she sit with hers? Or their friend groups? It's hard to really be specific not knowing the size and guest list.

Are any of your aunts/uncles/grandparents attending? If so, you could seat each of your parents with their family members. If any friends of either parent are attending, you could seat them at their tables too.

I’d do family tables separate from the bridal party table. Grooms parents, seat his closest relatives there. Your parents, seat your dad’s closest friends or family with him and your mom’s with her. Do you have siblings or nieces/nephews not in the bridal party you need to figure out where to divide?

Groom's dad had a table full of guests, but his mom only had one sister. As parents of the bride, we had a solid table of 8, but asked the venue if they could do a table of 10 and we added MOG & her sister to our table, with their backs to FOG's table.... It worked out.
