This decision affirms a prejudgment attachment order.  The trial court did not abuse its discretion in finding that the parties had not amended a fully integrated written contract which provided that all amendments had to be signed and in writing.  Under the Uniform Electronic Transactions Act (CC 1633.1 et seq.), it is not enough to show that a document was imprinted with an electronic signature.  It must also be shown that the signer executed or adopted the signature with the intent to sign the electronic record.and that the parties had agreed to conduct the transaction by electronic means.  Though the defendant produced “signed” emails, it did not supply evidence on the latter two points.  Also, the trial court’s conclusion that the parties had not modified the agreement by their conduct was supported by substantial evidence.
