Inviting Step Dad's Siblings?

If she is not close to them then I don't see why they would automatically be invited. Even if they were blood related, if she barely knows them they don't necessarily make the guest list.

I don't think you have to, but I would discuss it with your husband and make sure they aren't going to be offended.

If the guest list is big and the budget small, definitely leave them off

I wouldn't worry with it if she's not close with them? Not budget friendly so maybe they'll understand?

I would say no. Unless it is extremely important to you I would not invite them

My dad remarried when I was in college; I did not invite any of my step-mother's siblings to my wedding.

Dupe.

Agreed, if the budget is tight and the guest list is already large and she doesn't really know them, I think they should understand. I'd leave them off.

I am in the same situation. My mom knows all my step dad's siblings and they even go on trips together. But I have only met a few of them maybe once or twice years ago. We didn't invite any of them. It would be kind of weird to have strangers at my wedding that FH or I didn't know.

I didn't invite my step-parent's siblings or even my step-siblings for that matter. If they're not close, I wouldn't.

How long has your husband been in her life? I know you said you married 3 years ago, but if you were dating for 20 years before that, I'd probably invite his siblings, yes. Otherwise, I think you can leave them off the list.

If she's not close to them, they shouldn't be invited. This is about their nearest and dearest, not yours.
