The best way to prove that something had happened would be to present evidence and in the hierarchy of evidence, often the best evidence that one could present would be copies of the public records, and only if the actual records could not be presented. Like all death records, San Diego County Death Certificate are public records, and this makes them the best evidence that one could present in order to prove the death of the person named in the record. Now, one may ask why there is a need to prove the death of a person, and the answer to that would be because of the fact that death is something that would affect not only the persons whom the deceased would leave behind, but also the whole world.
This is because death would have effects that would be binding upon the whole world. Take, for example, the property of the deceased. Just because a person lives in one corner of the world does not preclude him or her from owning property at the other side of the world. The death of the owner of that property means that such property would have to pass on to the heirs of the decedent, and such succession shall be binding upon the whole world. Of course, outside of some unique circumstances provided for by law, the heirs could not adjudicate for themselves the property as there would be the need for court intervention in the form of a probate proceeding.
It must be noted that death is not something that courts could take judicial notice of, thus, there is the need to prove death, and again, the best way that this could be done would be through the presentation of the public records that are the death records. This is because these records enjoy the presumption of regularity which means that, absent any competent proof, the contents of the records would be considered accurate at all times. Combined with the nature of death records, this means that the mere existence of the death records should be construed as prima facie proof of the death of the deceased.
Copies of death records are available at both the state or national level and the county or local level. The best place to make the search would be at the local level as there would be fewer records here, but a search at this level is subject to the territorial limitations of county offices which means that the event should have occurred within the territorial limitations of the office where the search would be conducted, and the method of making the request would either be to make the request through mail or in person.
Copies of San Diego County Death Notices may also be requested online through the use of online databases. Mostly privately owned, these online databases could, nevertheless, provide information that is substantially the same as that of the official sources, and they could present the information faster, more efficiently, and considerably cheaper, but note that they are not official sources.
