Maintaining complete, 100% honesty with your legal counsel is not only encouraged but absolutely vital for building a successful legal defense or prosecuting a claim effectively. Protected strictly by the legal doctrine of attorney-client privilege, anything you disclose to your lawyer remains confidential, ensuring they can provide accurate legal advice. If a client hides unfavorable facts, past history, or damaging evidence, the opposing legal counsel can blindside the defense or claim at trial, destroying the case strategy unexpectedly.
