Officious intermeddler

An officious intermeddler is a person who voluntarily, and without request or pre-existing legal duty, interjects him- or herself into the affairs of another, and then seeks remuneration for services or reimbursement. Example: Person A leaves for vacation for two weeks during the summer. Person B mows A's lawn. B requests payment for this service. Under common law doctrine, B is not entitled to any payment from A beyond whatever A cares to give. If B tries to coerce payment, B is an officious intermeddler.
