Even the most detail-oriented people may accidentally leave something out of their trust. The idea of this can be scary because things that are not written into a trust may be subject to the probate process upon death. However, many estate planning lawyers will work with you to create what is known as a - pour-over will.- This will can essentially grab anything else that you did not name in your trust and move it to your trust. This can give many people peace of mind when they are not sure if they left something out.
