the deceased, and the paternal uncles of his father and grandfather, however remote1.

3—Likewise, sons and their male-line descendants.

471—The rule governing a residuary heir is as follows:

a—He takes the entire estate when he is the sole heir.

b—If a prescribed-share heir is present, he takes what remains after that heir’s share.

c—If the prescribed shares exhaust the estate, nothing remains for the residuary heir. The estate cannot, however, be exhausted by prescribed shares when a direct son or the father is present.

472—If two or more residuary heirs are present, the lines of residuary entitlement rank as follows:

1—The line of sons;

2—then the line of fathers;

3—then brothers and their sons;

4—then paternal uncles and their sons;

5—then the bond of manumission: the emancipator and his agnates who are residuaries in their own right2.

473—The heir belonging to the nearer line takes precedence.
