MEORANDUM AND ORDER
K. GARY SEBELIUS U.S. MAGISTRATE JUDGE
This matter comes before the court upon Plaintiffs’ Motion to Compel Grant Davis’ Full and Complete Responses to Plaintiffs’ Third Requests for Production. Plaintiffs in the above-captioned actions have asserted legal malpractice claims against their former attorney, Defendant Grant Davis. Plaintiffs have filed substantially similar motions to compel in the above-captioned cases, and defendant has filed nearly identical response briefs. In the interest of expediency, the court addresses all of the pending motions to compel in this order.
Plaintiffs in the above-captioned actions are the individuals or surviving heirs of individuals who filed state court suits against Robert Courtney-a Missouri pharmacist who diluted chemotherapy drugs-and against drug manufacturers Eli Lilly & Company and Bristol-Myers Squibb Company. Defendant represented many of the three-hundred-plus plaintiffs in these Missouri state court suits, including the plaintiffs who subsequently filed suits against him in this district. Highly summarized, plaintiffs contend defendant’s actions related to an alleged aggregate settlement resolving the Missouri state court actions constitute legal malpractice.
Plaintiffs explain that during the course of this litigation, defendant has made inconsistent representations regarding the malpractice insurance policy or policies implicated by the suits against him. To clarify the issue regarding insurance coverage, plaintiff propounded certain document requests aimed at gathering information about insurance coverage. Plaintiffs move for an order compelling defendant to fully respond to Request for Production No. 3, served in all of the above-captioned cases. The request seeks, “All correspondence between Defendant and any insurance company or its representatives relating to the claims made in this lawsuit or denials of insurance of the claims made in this lawsuit, including any reservation of rights communications.”
Defendant initially objected to the request on the basis that it called for defendant to produce documents subject to a protective order in the underlying Missouri state court proceedings, called for information protected by the work-product doctrine, and called for information protected by the insurer-insured privilege. In response to the motion to compel, defendant continues to assert an insurer-insured-privilege objection. In addition, defendant also argues that plaintiffs already possess all of the relevant insurance policy information.
Fed. R. Civ. P. 26(b)(1) provides that “[f]or good cause, the court may order discovery of any matter relevant to the subject matter involved in the action.” When a party objects to a discovery request, the discovering party may file a motion to compel. When a motion to compel asks the court to overrule certain objections, the objecting party must specifically show how each discovery request is objectionable. Objections initially raised but not asserted in the objecting party’s response to a motion to compel are deemed abandoned. Similarly, any objections not asserted in the initial response to a discovery request but raised in response to a motion to compel are deemed waived.
Defendant asserts several arguments in response to the motion to compel. First, defendant argues that plaintiffs already possess all of the necessary information to evaluate the insurance policies. This argument is akin to an objection that the discovery request is unduly burdensome because it is cumulative or duplicative. But defendant did not initially raise this objection when responding to the request for production. Therefore, the objection is waived. Even considering the merits of the objection, the court would overrule it. The fact that plaintiffs already possess certain information on a topic does not itself render a discovery request unduly burdensome or unreasonably cumulative or duplicative.
Defendant also attempts to assert a belated objection akin to an attorney-client privilege objection. Defendant’s privilege log contains several entries indicating that certain documents were withheld because they are “attorney-client communications” in addition to being protected by the insurer-insured privilege. Defendant did not originally assert an attorney-client privilege objection, nor does defendant attempt to support this objection in his response brief. This objection is also waived and would in any event be overruled because of defendant’s failure to support the objection. That leaves only the insurer-insured privilege objection.
Defendant has submitted a privilege log in support of his insurer-insured privilege objection. In their reply briefs, plaintiffs argue that the court should overrule defendant’s privilege objection because defendant did not provide a privilege log until after plaintiffs filed their motion to compel. Fed.R.Civ.P. 26(b)(5) requires an objecting party to expressly make a claim of privilege and to “describe the nature of the documents, communications, or tangible things not produced or disclosed-and do so in a manner that, without revealing information itself privileged or protected, will enable other parties to assess the claim.” This district has generally required that the objecting party must provide this information to the discovering party at the time the information is withheld. Failure to timely provide this information may result in a waiver of the privilege. However, waiver is a harsh sanction and is usually reserved “for those cases where the offending party unjustifiably delayed in responding to the discovery requests or acted in bad faith.”
In this case, it is not entirely clear to the court when defendant’s responses to Request No. 3 were due. Instead of attaching the discovery request and responses, as required by the local rules,  plaintiffs quote Request No. 3 and defendant’s response to that particular request in their memorandums in support of their motions to compel. While this is sufficient to enable the court to rule on the merits of the motion, it makes it difficult to determine with certainty which sets of requests for production contained the specific request at issue and when defendant’s responses were due. Even if defendant belatedly submitted the privilege log, any delay here is not so great that the court would find defendant has waived a privilege.
Turning to the merits of defendant’s insurer-insured privilege objection, Fed.R.Evid. 501 requires that “in a civil case, state law governs privilege regarding a claim or defense for which state law supplies the rule of decision.” Federal jurisdiction in this case is based on diversity of citizenship. In the Booth and Schmitz cases, Judge Crow ruled that Missouri substantive law governs plaintiffs’ tort claims. Throughout the litigation of the above-captioned cases-including briefs on discovery motions, motions for a determination of a point of Missouri law, and during conference calls with the undersigned-the parties have never disputed that Missouri substantive law governs the claims and defenses in these cases. Because it appears Missouri law supplies the rule of decision for the claims and defenses in these cases, Missouri law would also govern the application of privileges. Although plaintiffs state they do not concede that Missouri privilege law applies, they make no other statement about which state’s law they believe should apply if not Missouri law. Therefore, the court will apply Missouri law here.
In State ex rel. Cain v. Barker, the Missouri Supreme Court recognized an insurer-insured privilege as a variant of the ...
