Of one who raises another in his house as son and heir who is neither.
 We have discussed above the case of a wife who, during her husband's life or after  his death, falsely claims that she is pregnant though she was not. Now we must  consider the case of a husband and wife who, to the disherison of the true heir,  raise as son and heir one who is neither son nor heir but a supposititious child or one  begotten by another. At the complaint of the true heir let them be summoned to  appear before the justices by this writ.
Writ for having the bodies of such a one and his wife before the justices.
 1The king to the sheriff, greeting. We order you to have before our justices etc.  the body of A. and of B. his wife (or the body of either of them) to answer C., son  (or grandson or other heir) of the said A., who claims to be the heir of A., as  to why they cause D. to be raised as son and heir of the said A., to the disherison  of C., when D. is not and cannot be the son or heir of B., as the said C. says. And  have there this writ. Witness etc. If the father and2 mother appear, or one of them,  and produce the child they are raising, acknowledging him in court as their son and  heir, then, if the presumption of legitimacy which admits of no proof to the contrary  lies in their favour, as where he was born of a wife able to conceive, though  begotten by someone other than her husband, or if he was substituted while  husband and wife lived together, there being no impediment on the husband's  part whereby he could not beget nor on the wife's whereby she could not conceive,  for example sterility or old age, such issue will be legitimate. But if the true heir  can demonstrate the contrary it will be otherwise, even though the parents have  acknowledged the contrary in court, [that is], provided it is proved. For an  acknowledgment made in court must be in accord with nature and consonant with  truth. If while such plea is pending and before the status of the child is ascertained  he dies and another is substituted for him and raised as heir, let the following writ  issue on the plaint of the true heir.
Where the true heir dies within age and the guardian substitutes another, a stranger; or if it is suspected that he is dead, a writ that he be produced and viewed.
 The king to the sheriff, greeting. A. brother of B., who claims to be the heir of the  said B. if C. the wife of D. and the daughter of the said B.
