Article 882. When the bequest is of a thing specific and determined, belonging to the testator, the legatee acquires the property thereof upon the death of the testator and makes the pending fruits or rents his own, but not those which were due and unpaid before said death.

The thing bequeathed shall, from the same moment (of said death), be at the risk of the legatee who, therefore, shall bear its loss or impairment, and he shall also be benefited by any increase or improvement thereof.
