n. the act of intentionally and permanently giving up, surrendering, deserting or relinquishing property, premises, a right of way, a ship, contract rights, a spouse and/or children. Abandonment of a spouse means intent at permanent separation, and with children a lengthy period of neither contact nor any support. In maritime law abandonment has a special meaning: when an owner surrenders a ship and its contents to a trustee for the benefit of claimants, particularly after a wreck. If one invents something and does not get a patent but allows others to use the invention or dedicates it to public use, the right to patent is probably abandoned. Confusion arises over abandonment of water rights, mining rights, or rights of way, since mere non-use is not sufficient to show abandonment.
