If you sell a property as a life annuity to your child (who is your presumptive heir at the time of the sale), tax law considers this transaction as a gift, which will be charged against the disposable portion of your estate at the time of your death. In other words, the value of the property will be taken into account to determine whether all your children have received their reserved share. If this is not the case, your child will be required to pay compensation to the other children who have been disadvantaged (known as a reduction indemnity) (Article 918 of the French Civil Code).
