Once you have signed your living trust document, the next step is to change titles and beneficiary designations to your trust. This is called "funding" your living trust. This is probably the most important step in preparing a living trust. If you have signed your living trust document but haven't changed titles and beneficiary designations, you've simply wasted your money. You may have a great trust, but until you fund it, it doesn't control anything - because your living trust can only control the assets you put into it.
