This is an appeal from the district court’s grant of summary judgment in favor of Chevy Chase Bank on plaintiffs’s complaint seeking Truth and Lending Act rescission under 15 U.S.C. § 1635. Specifically, the plaintiffs sought judicial enforcement of their alleged cancellation of a loan transaction, claiming that they delivered the notice of rescission to the person who served as witness and notary public on the loan documents at the same time they signed and delivered the loan documents themselves. The case was referred to a magistrate judge under 28 U.S.C. § 636 et seq. The magistrate judge filed a report and recommendation recommending that the bank’s motion for summary judgment be granted. After conducting a de novo review, the district court, in a separate opinion, adopted the magistrate judge’s report and recommendation and entered summary judgment for the bank.

We review de novo the district court’s order granting summary judgment, applying the same legal standards that governed the district court. Info. Sys. and Networks Corp. v. City of Atlanta, 281 F.3d 1220, 1224 (11th Cir. 2002).

After reviewing the record and reading the parties’ briefs, we conclude that the district court correctly granted summary judgment for the bank for the following reasons: (1) the bank objected to service of process in its answer and thus did not *279 waive its objections to insufficient service of process and jurisdiction; (2) the plaintiffs are estopped from seeking judicial enforcement of an alleged cancellation, where, at their behest, a court of competent jurisdiction necessarily found that the subject transaction had not been rescinded and was in full force and effect; and (3) even if the fully executed notice of cancellation was delivered as alleged, the delivery was defective and cannot serve as the basis for judicial enforcement.

AFFIRMED.
