Fraudulent Entry Into Dwelling
Deborah Dunn told the homeowner she was a city inspector checking for gas leaks. Once inside the living room she unlocked a window for later entry and stole jewelry. The use of the false identity satisfied the breaking element because the homeowner's consent was obtained by fraud.
Post-Closing Fraud Claim Survives
Dolores Diaz sold her home to Delta Dynamics. The deed contained no warranty about the roof. After closing the buyer discovered the seller had concealed active leaks. Because the nondisclosure amounted to fraud the merger doctrine did not bar the buyer's contract claim.
Fraud Pleading Must Be Specific
Dominion Capital sued Dawson Steel alleging the defendant had misrepresented its financial condition to induce a loan. The complaint stated only that the statements were false. The court dismissed the claim because the circumstances of the alleged fraud were not pleaded with particularity.
Lawyer Must Withdraw From Fraud
Duarte Shipping asked its lawyer to prepare documents that would conceal inventory from creditors. After the lawyer explained the limits on assisting fraud the client insisted on proceeding. The lawyer was required to withdraw from the representation.
Veil Pierced For Fraudulent Use
Darrell Duncan formed Delta Dynamics with minimal capital and used the entity to contract with suppliers while diverting all receipts to his personal account. When the corporation defaulted the court disregarded the corporate form because the entity had been used to perpetrate fraud.
Will Contest Based On Fraud
Diane Dawson offered a will for probate. Delilah Duran challenged it claiming the testator had been told the document disinherited no one when it actually left everything to Diane. The contestant bore the burden of proving the will was procured by fraud.
