I believe one checking account is sufficient, but (spouses) should work together in making a budget and reconciling the budget to their spending each month. If that does not occur, problems will surface.

Newlyweds should get in the habit early in committing to retirement plans, especially those with matching features. Roth IRAs are a great vehicle for the newlyweds to start saving for the long term. They should understand the power of compounding and how their savings relates to their goals of buying a house or a newer car.
