Etiquette Snob here… lol
When it comes to social events that are Hosted… the Man may be paying… but the Woman is ALWAYS the Host.
Your Mother is the Guest with Highest Distinction at your Wedding… followed by the Mother of the Groom.
(Also the order in which they should be sat in the Church at the Wedding… Moms last… first his, then yours… then the Processional begins)
Which order for your situation depends on what is to happen next…
If it is during the Speaches portion… your Mother should be introduced first… then your Dad who would then carry on with his Speach (usually he’d open with something nice about his Wife / Mother of his children… but in a Divorce situation that may be pushing it)
If it is just introductions… then it should go:
From most distant to closest…
So Bridal Party, Parents, B&G
His Parents (Dad – Mom) and then Your Parents (Dad – Mom)
If someone is divorced then the order stays the same… so in this case Your Dad & Wife, then Your Mom & Husband
Then you guys.
If you put GodParents or GrandParents into the mix… they come before each respective Parent
So… Groom’s GodParents – GrandParents – Parents
Bride’s GodParents – GrandParents – Parents
I suggest that you explain to your Mom that she is the Most Honoured Guest in the room, (top dog, gets top billing) and so she will always be the last introduced before you the Bride & Groom…
If you explain that element to her and WHY she may more readily buy into the concept.
She is the cat’s meow on your Wedding Day for sure !!
Hope this helps,
