Mall operators in the U.S. have been strapped for cash amid the pandemic as people have stayed indoors and resorted to online shopping.
Retailers, including J.C. Penney Co Inc, one of CBL's biggest renter, already grappling with customers' abandonment of traditional stores for online shopping have also resorted to bankruptcy filings.
CBL's filing follows that of Pennsylvania Real Estate Investment Trust earlier on Sunday, which filed a chapter 11 petition to execute a prepackaged financial restructuring plan.
The bankruptcy was earlier reported by Bloomberg, which said the process will give the company a chance to continue operating while reorganizing its finances and business.
In a filing on the U.S. Bankruptcy court for the Southern District of Texas, CBL listed both estimated assets and liabilities in the range of about $1 billion to $10 billion.
CBL had announced in August that it had entered into a restructuring support agreement with a group of bondholders to allow it to strengthen its balance sheet and organization.
