don't add her husband's name on the deed of the house!
I know a friend, her hubby owe credit card loan and can't repay. Finally need to go bankrupcy. Fortunately the house is only under the wife's name and therefore not affected.
If the house is under husband and wife's names, the credit card company can force the couple to sell the house, and use half of the asset to repay the debt.
No matter how much your friend loves her husband, she must protect herself so that she will not fall apart when something bad happens.
