What are some of the most common Estate Planning errors that are made?

There are many mistakes that are made in developing your Estate Plan, but here are some of the most important: (1) failing to name a contingent beneficiary on wills, insurance policies, etc., (2) not reviewing your beneficiary designations on a regular basis, (3) naming your estate as the beneficiary of an IRA, which can lose tax breaks, (4) forgetting to remove your ex-spouse as beneficiary on an IRA or insurance policy, (5) leaving assets directly to a minor without naming a Guardian, (6) not having a Residuary Clause in a will, (7) having an imbalance in family assets, i.e. one spouse has much more in assets than the other. And the last two are related: (8) not dealing with your own mortality and what happens after you die, and (9) not planning at all.  You will be wise to begin planning now.
