Under Art. 778 of NCC, succession may be:
1. Testamentary or testate succession is that which results from the designation of an heir, made in a will executed in the form prescribed by law (Art 779 NCC).
2. Legal or intestate succession is the effected by operation of law since the decedent did not execute a will.
3. Mixed succession is that effected partly by will and partly by operation of law.
The inheritance of a person includes not only the property and the transmissible rights and obligations existing at the time of his death, but also those which have accrued thereto since the opening of the succession. (Art. 778 NCC). An heir is a person called to the succession either by the provision of a will or by operation of law. Devisees and legatees are persons to whom gifts of real and personal property are respectively given by virtue of a will. (Art. 782).
