Section
Any donor may revoke his gift before the donee has taken possession, though such revocation is disapproved. It is valid only when expressed verbally. After delivery, revocation is forbidden and ineffective—unless the donor is the father1, in which case he may rescind subject to four conditions:
1 he has not renounced his right to revoke2;
2 the gift has not undergone an inseparable increase;
3 the item is still within the donee’s estate; and
4 it has not been pledged as collateral.

A free father may appropriate whatever he wishes from his child’s property, provided five conditions are met:
1 the child suffers no harm;
2 neither of them is in a terminal illness;
3 he does not then bestow it on another child;
4 the appropriation is completed by taking possession together with a verbal declaration or an internal intention; and
5 what he takes is an existing, tangible asset—thus he may not take over a debt owed to him by his child, nor may he simply discharge himself3 of it4.

The child, for his part, may not demand repayment of any debt his father owes him; rather, if the father dies, the child claims it from the estate out of the principal before distribution.
