Can my ex come back to haunt me with old debts?

Can my ex come back to haunt me with old debts? The scary truth: without proper protection, undisclosed debts can come back to cause trouble after separation. To protect yourself, Senior Associate Hayley Mitchell advises that any couple separating - married or not - should enter a separation agreement. Not only does a well-drafted separation agreement deal with all of the financial claims you could potentially make against each other, it also prevents your ex from making any future claims as well.
