Non-payment of credit card debt: If you fail to make the minimum payments on your credit card for an extended period of time, the credit card company may decide to sue you for the unpaid debt. 

They may also sue you if you’ve defaulted on your credit card agreement in some other way.

Breach of contract: When you sign up for a credit card, you enter into a contract with the credit card company.  

If you violate the terms of the contract in some way, such as by exceeding your credit limit or making late payments, the credit card company may sue you for breach of contract.

Fraudulent activity: If the credit card company suspects that you’ve engaged in fraudulent activity 

such as using a stolen credit card or lying on your credit card application, they may sue you to recover any losses they’ve incurred as a result of your actions.

Disputes over charges: If you dispute a charge on your credit card and the credit card company doesn’t agree with your dispute, they may sue you for the unpaid amount.

Statute of limitations: Credit card companies have a limited amount of time in which they can sue you for unpaid debt.
