California Code, Financial Code - FIN § 15204

(a) Upon any merger effectuated as provided in this article, all property, property rights, and interests of the merged credit union shall vest in the surviving credit union, without deed, endorsement or other instruments of transfer, and all debts, obligations and liabilities of the merged credit union are assumed by the surviving credit union under whose charter the merger has been effected. Thereafter the charter of the merged credit union is void, and the existence of the merged credit union as a legal entity separate from the surviving credit union terminates.

(b) Whenever a credit union having any real property in this state merges with another credit union and vests that real property in the surviving credit union, the filing for record in the office of the county recorder of any county in this state in which any of the real property of the disappearing credit union is located of the certificates of merger and requisite attachments, as required by Section 15202, shall evidence record ownership in the surviving credit union of all interest of the disappearing credit union in and to the real property located in that county.
