Birth, marriage, and death records. While these records are parts of lives lived, they are all also valuable tools to help live those lives—but not always in the ways one might expect. Sure, many people use these as part of genealogical research or to perhaps apply for or renew certain documents. But that’s not all these records can be used for.
While there are different types of birth, marriage, and death records—in fact, each one of these records could have its own post given the different types—we are going to concentrate on some of the most basic interpretations of these records. This post will try to help and answer some of the more frequent questions about these records and why they are necessary and why local governments and the State Bureau of Vital Statistics keep these records permanently.
Why are these records so important?
At an elemental level, birth certificates are used to establish one’s identity, age, and citizenship. Marriage certificates are used to establish proof of marriage, name changes (e.g., one spouse taking the other’s last name), and as a document showing the marriage was recognized by a governmental entity (e.g., marriage license). Death certificates are used as evidence that an individual has passed away and, therefore, that their legal rights are terminated, and ownership of their assets must be transferred.
Now that the basics have been established, let’s dig a little deeper.
How do these records apply to a person’s legal rights?
All of these records are crucial in establishing a person’s legal rights, establishing identity and citizenship, accessing services, education, power of attorney, and inheritance rights, to name a few examples.

A person’s birth certificate is the basic and most fundamental legal document establishing a person’s identity and legal rights. Other applications include:
- Establishing parental rights and custody, as well as proving guardianship.
- Establishing legal paternity (in cases of visitation and child support).
- Also required to apply for and receive government benefit programs and social services (e.g., disability support, housing assistance, etc.).
Marriage certificates are the primary evidence provided by a governmental entity that a marriage has lawfully taken place and recognizes a couple as a marital partnership. A few more of the ways these are relevant to a person’s legal rights are:
- Ownership of property. In Texas, most assets acquired during the marriage are community property.
- If someone passes away intestate, the marriage certificate allows the surviving spouse to inherit the deceased spouse’s estate.
- Gives the spouse the right to make medical decisions when their partner is incapacitated whether or not there is legal documentation (e.g., DNR, Medical POA).
- Establishing the right for the spouse to receive partial benefits of their spouse’s Social Security or pension.
The death certificate is the official record proving that an individual has died and is the determiner of terminating a person’s legal rights. It is also used by the government and survivors to:
- Initiate probate and allow heirs to legally inherit property.
- Claim any life insurance benefits.
- Close any bank and credit card accounts.
- Authorizes a funeral home to bury or cremate the deceased.
How do these records help with emergency management?
What many people may not realize is how important these records are to emergency management. Vital records are critical in aiding rapid response, and the foundation of long-term recovery after a disaster. They provide continuation of protection of legal and financial rights of individuals as well as expedite legal recovery after a disaster.
Birth certificates, again, not just establish identity, prove citizenship, and access government benefits, but are also used to:
- Access lost government documents (e.g., social security cards, driver’s licenses, etc.).
- Needed for proving legal ownership of assets during recovery and securing housing.
- Help to prove insurance claims on lost property or life.
Marriage certificates act as proof of a legal matrimonial partnership which helps both spouses—or the surviving spouse—recover from a disaster. This includes:
- Securing government assistance by establishing familial relationships within the household.
- Providing proof of next-of-kin relationships when filing claims for insurance or proving joint ownership of property.
- Helping to prove joint ownership of property and fiscal assets.
- Furnishing access to shared bank accounts and legal documents that may have been destroyed.
Death certificates help with emergency management by providing data on deaths caused by disaster-related incidents, permits government officials to review the overall scope of the disaster, and track death and injury patterns. Other uses include:
- Resource and fiscal allocation planning.
- Identifying future risks, mitigation planning, and medical data collection.
- Determining mortality rates directly or indirectly related to the disaster.
How do these records apply to public health?

The final way we are going to look at these vital records is how they relate to public health by identifying risk factors, informing policy, helping research, and assisting in tracking significant public health events.
Birth certificates help to provide population data, assess trends in infant and maternal health, as well as help to better focus on medical services for more vulnerable populations. They also inform and give public health officials the tools to:
- Track birth rates, population growth, and migration.
- Statistically identify and trace infant risk factors based on weight, gestational period/age, congenital defects, and race.
- Assess the quality of pre- and post-natal infant health and maternal care programs and where fiscal and personnel resources should be allocated.
Marriage certificates are key in public health management because they are critical components of state vital health statistics. In Texas, these can be used for research—such as tracking family formation—and accessing family health services. Other ways marriage certificates help inform public health policy include:
- Demographic analysis uses these records to track and assess demographic changes.
- Proving eligibility and enabling access to public health services.
- Adding spouses to insurance plans and creating access to healthcare services.
Death certificates are a primary source for public health authorities researching and tracking mortality patterns, causes of death, and recognizing potential public health emergencies. Other primary uses are:
- Assisting in allocation of funds for research into tracking causes of death, analyzing patterns, and creating statistics to create policy.
- Helping to understand and track morbidity through environmental, health, and social factors.
- Presenting data to governmental entities to help inform public health policy.
Summary
While these records—birth, marriage, and death—are considered vital records and are kept permanently by local governments, they are not just for collecting dust or taking up server space. They are vital for a great many reasons– more that can be encompassed in one post.
