Funding your Trust with $20 is a common but optional practice, which involves either taping or stapling a $20 bill to the Trust agreement. This symbolic gesture demonstrates the intent to fund the trust until actual assets are transferred.
Alternatively, you can fund your Trust by transferring assets directly. This often requires changing the title of your assets (often referred to as "re-titling"). In order for your Trust to exist in some states, you must fund your Trust in addition to signing it based on your state’s guidance.
