If you do too much reading online about the difference between wills and trusts, then you are likely to think of the two as something that you have one or the other. That is a myth.
One of the key concerns for people planning their estates today, is whether they should use a will or a trust. Everyone seems to have an opinion about which one of the two main estate planning vehicles is better for general purposes. The two are often discussed, as if they are oppositional.
It is likely that when you pass away you will have some assets that for one reason or another were never put into your trust. Those assets will need to be distributed by your estate and often under the guidance of the probate court. You need a will so what you want done with those assets can be done.
Often that will is only a “pour-over will” that directs that everything should be transferred to your trust. However, there are other things you might also need to accomplish with a will, such as directing who should be appointed as a proper guardian for your minor children. You also might have some assets you do not want to go through a trust for other reasons, for which a will would be appropriate.
The best way to make sure you have all the documents you need in your estate plan, is to hire an estate planning attorney to draft your plan.
