A mental patient can make shipping contract?

Usually any person can make a contract, although the law sometimes protects certain classes. When a person is denied full contractual capacity, the purpose is to protect and not to prohibit and any difficulty in enforcing the contract is usually experienced by the party with full contractual capacity. This particularity applies to minors, drunks or mental patients who have less than full capacity. However, mental patients will be liable on contracts made during a lucid period (i.e. when they are sane). A mental patient whose property is under the control of a court may not make a contract.
