You can make a mistake if you do not think of your estate plan when you think ahead to retirement, according to Life Health Pro in "Bequest goals: more than just an issue for the wealthy."
The primary reason for this is that if you would like someone else to have a given asset after you pass away, then you need to make it so your retirement plan preserves that asset so that you will still have it to pass on. For example, if you would like to leave your home to your children, then your retirement plan needs to be sufficient enough for you not to have to sell the home to have funds to live on when you are no longer working.
This is true whether you have a large mansion or a more modest house.
What this means is that you should not think of life as entirely separate stages when you do your planning. Think about what type of estate you want to leave behind when you plan for your retirement and act accordingly.
An estate planning attorney can help guide you through your planning.
