Is the acknowledgment of lineage by an heir valid if it results in the acknowledging heir being deprived of their inheritance share?

Primary text

The lineage established through acknowledgment must be upheld even if it causes the acknowledging heir to be excluded from inheritance. The validity of lineage is established, and the consequence of inheritance follows, similar to a case where the lineage is proven by testimony. To argue that the effect of establishing lineage (inheritance) is cut off is invalid.
