Even if the debt has passed the SOL in your state for suit (variable by state) and even the federal SOL for reporting (roughly 7 years from when the debt discharged) a collector may still pursue you for this money if you owe it. They will just never be able to collect it or report it if you don't allow them to, although they will certainly try and hope you are ignorant enough of the law that they get money from you.
Note: Below we’ve listed our favorite offers from credit unions and lesser known banks that provide balance transfer offers up to 12 months. If you need a longer intro period, you might be better off paying a standard 3% balance transfer fee for a card like the Discover it® Balance Transfer which offers an intro 0% for 18 months on balance transfers (after, 13.99% - 24.99% Variable APR).
Next, estimate your monthly spending habits for other expenses such as gas, groceries and entertainment. Create a limit, based on your income, of what you can spend in each of the different categories of expenses. For example, if you tend to spend $400 a month on groceries, try to stick to $300 a month on groceries by making changes like buying generic brands, using coupons, and resisting impulse purchases.
