Which behavior demonstrated by a client diagnosed with depression indicates a need for suicide precautions?

I believe the answer is: The client asks to meet with a lawyer to take care of unfinished business.

Large majority of depressed patient that ask to meet with a lawyer would most likely do it to create a will that dictate how his assets shall be distributed after his death. The client would most likely do this when he had the intention to end his life in the near future.
