In California, to modify your living trust, you need to create an amendment to the original trust document. This amendment should clearly outline the changes you wish to make, whether that's adding or removing beneficiaries, changing trustees, or altering distribution instructions. Be sure to include the date, your name, the name of the trust, and the date the trust was originally created. Just like the original trust document, your amendment needs to be signed in the presence of a notary public. If there are numerous changes to be made, it might be more practical to draft a complete restatement of the trust. A restatement allows you to rewrite the whole trust, yet it maintains the original date and title of the trust, which is advantageous to avoid the process of retitling assets. In this restatement, you can include all the new changes you want, and these new provisions will replace the existing ones in entirety.
