Without a clear, detailed, and irrefutable estate plan issues related to the control and ownership of your assets will be thrown into the courts. They will need to be adjudicated, and the result may be contrary to your intentions at best. At worst, it could plunge your enterprises into extreme chaos and lead to the unraveling of all that you spent your life putting together. You may still be relatively young and vigorous, or you may be getting on in years and nearing retirement. No matter your age or physical condition, you never know when illness or accident might incapacitate or kill you. If you have accumulated the kinds of assets discussed above, then you should sit down with a lawyer and start developing an estate plan. If you already have a lawyer that you consider a confidant, then you should speak with them about your desire to put an estate plan in place. Such legal documents should be drawn up by a specialist, and your family counsel can help you choose one.
