I was told by one (and only one) financial planner that I should not co-mingle my retirement lump sum with any other tax deferred monies. The reason, he said, is in the case of a law suit, retirement monies cannot be attached by any court order while all other monies can. He gave the example of O.J. Simpson. If he had co-mingled his funds, he would have had everything taken away.While I am not likely to be sued, it can happen to anyone. Has anyone heard of this? Is it anything to be concerned about?
