Can a credit card company put a lien on a house that you own with another person or by yourself to try to collect their money?
It depends. Some credit cards come to you as equity loans (you activate the card, it gives you a limit on the card equal to the equity on your house) and if you don't pay off the loan, the house belongs to the company. If it is a regular credit card and you don't pay, they may take you to court and win a judgment against you. That would allow them to put a lien on the house in the amount of the judgement. So, to answer your question, yes, there are ways that a credit card company can put a lien on your house.
