If you are of retirement age, it is recommended that you create a Power of Attorney. While you are more to live a long life, rather than die unexpectedly, you may be in a state of reduced capacity for some of those years. By creating a Power of Attorney now, you ensure that someone you trust will be able to step in and attend to your business affairs should you be unable to do so.
You should also create a Healthcare Directive. Much like a Power of Attorney, the Healthcare Directive ensures that your medical wishes will be respected since someone you trust will be speaking on your behalf in all of your medical decisions.
Finally, put your assets in a trust. Long-term care is the single greatest threat to asset preservation. By putting your assets in a trust, you ensure that all you have worked hard for will be preserved and available to be passed down to your heirs.
