A fundamental requirement for a valid and enforceable contract under Ghanaian law is that the agreement must be lawful. Even where offer, acceptance, consideration, intention to create legal relations and capacity are present, the courts will refuse to enforce a contract whose formation or performance is tainted by illegality.
Illegality operates as a complete bar to enforcement in appropriate cases because the courts will not lend their authority to transactions that violate the law or undermine public interest.
