Presumption in the context of "Burden of production"

A deed is a legal document that is signed and delivered, especially concerning the ownership of property or legal rights. Specifically, in common law, a deed is any legal instrument in writing which passes, affirms or confirms an interest, right, or property and that is signed, attested, delivered, and in some jurisdictions, sealed. It is commonly associated with transferring (conveyancing) title to property. The deed has a greater presumption of validity and is less rebuttable than an instrument signed by the party to the deed. A deed can be unilateral or bilateral. Deeds include conveyances, commissions, licenses, patents, diplomas, and conditionally powers of attorney if executed as deeds. The deed is the modern descendant of the medieval charter, and delivery is thought to symbolically replace the ancient ceremony of livery of seisin.

The traditional phrase signed, sealed and delivered refers to the practice of using seals; however, attesting witnesses have replaced seals to some extent. An agreement under seal may also be called a contract by deed or a specialty; in the United States, a specialty is enforceable without consideration. In some jurisdictions, specialties have a liability limitation period of double that of a simple contract and allow for a third party beneficiary to enforce an undertaking in the deed.

A legal fiction is a construct used in the law where a thing is taken to be true, which is not in fact true, in order to achieve an outcome. Legal fictions can be employed by the courts or found in legislation.

Legal fictions are different from legal presumptions which assume a certain state of facts until the opposite is proved, such as the presumption of legitimacy.

An individual's or community's religious orientation involves presumptions about the existence and nature of God or gods, religious prescriptions about morality and communal and personal spirituality. Such presumptions involve the study of psychology, ethics, sociology and anthropology.
