Descendants of a third party

Where the testator has made provision for the descendants of a third party without more precise identification, then in case of doubt it is to be assumed that provision is not made for the descendants who have not been conceived at the time of the devolution of the inheritance or, if the gift is made subject to a condition precedent or together with the specification of a date of commencement and the condition is satisfied or the date occurs only after the devolution of the inheritance, at the time when the condition is satisfied or on the date of the commencement.
