If a claim for Equitable Distribution is not filed prior to absolute divorce being granted then neither spouse can go back afterwards to make that claim. If she files a claim for ED prior to the divorce being granted and asks for these items then it’s possible ED would need to go through court and these items be decided on.
If she does not file for ED then you are using the agreement as ED. If these items are in your possession and not on a list, it’s your decision about whether or not you want to give them to her.
My husband’s ex did much this same thing and even ask for more items after their agreement was renegotiated. I will tell you the same thing I told him. If you give in on this item then next week she will think of something else that she “should” have gotten and it will be neverending. If it’s not that important to you, and you don’t care, then give it. If it’s something that you do not want to give up, then stand your ground and tell her no.
