Can a bank take my house if my sister only in on the loan?

If your sister is the sole borrower on the loan, the bank can only pursue her for repayment. However, if the loan is secured by the house and she defaults, the bank can initiate foreclosure proceedings on the property, regardless of your ownership status. If you are a co-owner of the house, you may still have rights, but the bank can sell the property to recover the debt. It's advisable to consult a legal expert for specific guidance based on your situation.
