As a co-agent with her husband, a wife had a duty to the principal to act on her knowledge of her husband’s actions to protect the principal from theft and fraud by the husband as co-agent, and is therefore jointly and severally liable for the funds taken improperly from the principal’s accounts. The court also retroactively imposed a constructive trust upon the residence of the husband and wife, which was improved using the appropriated funds and transferred from the husband to the wife as part of a sham divorce.
