Op, this is not worth your concern. It's your DH's family. Whatever discrepancy exits, including the discrepancy of how they do it and how you would do it, it does not matter. It should not matter to you at all. It's not worth an ounce of discord in your marriage. Whatever money is involved, assume it's a whole lot less than marriage counseling.
Or your DH being put on the outs with his siblings. If DH has a problem with it or if it's a serious financial strain for you two he should talk to his siblings about it.
But really it sounds like you are the new DIL on the scene aand think the only proper way to do things is they way in which your family of origin does them.
Or you simply do not have enough going on in your life. Don't borrow trouble instead purse a hobby I've heard Barre classes are a thing.
