Why is it important for couples to understand what community property is, and the legalities surrounding it?

If couples are knowledgeable about community property, then they can position themselves to take advantage of its various benefits and they can take steps to avoid losing those benefits if they decide to move to a state where there is no community property. But not only is knowledge about community property laws important to couples; that knowledge is of significant importance to professionals, such as financial planners, insurance agents, lawyers and accountants, where the lack of competency could subject the professional adviser to a claim.
