Maintenance for the mother-to-be of an heir

Where at the time of the devolution of the inheritance the birth of an heir is to be expected, the mother-to-be, if she is incapable of maintaining herself, may claim appropriate maintenance from the estate until the birth or, if other persons are also entitled as heirs, from the share of the inheritance of the child. When the share of the inheritance is calculated, it is to be assumed that only one child will be born.
