Yup; we already had our conference and submitted initial disclosures, but they failed to provide documents pursuant to Fed.R.Civ.P. 26(a)(1)(A)(ii) and my documents are all already in record.
The schedule has been finalized, but AFAIK that doesn't affect their requirement of sharing their documents with me. They filed counterclaims and my understanding is in order for their counsel to file counterclaims in good faith they must have some sort of documentation/evidence to support those claims. As the claims are 'paper based' my understanding is they were required to provide that documentation to me but failed to do so.
At this point, I'm thinking sending a notice letter demanding they provide all documentation supporting their claims pursuant to Fed.R.Civ.P. 26(a)(1)(A)(ii) or I will move the court to compel them to do so is the best approach.
