Testate succession occurs when a valid will made by a person of sound mind ensures their property passes to those they choose after death. A will must meet formal requirements including being made voluntarily without influence, and being properly executed with witnesses. The will can be revoked but a later marriage does not revoke it if contemplating that marriage. If dependents are not provided for reasonably, the court can order provision from the estate based on the deceased's property, the dependents' means and needs, any gifts made, conduct, and reasons for exclusion.
