Despite the prevailing view, children born to unmarried parents are commonplace. Historically, children in this category were treated poorly by both society and the law. In many cases, they had no right to inherit from either parent. This legal scheme eventually changed and provided means for these children to inherit from their mothers, but rarely their fathers, until the late 1960s.
If you are a nonmarital child or have a nonmarital child, it is essential to understand how rights to inherit are formed and defined. Failure to adequately provide estate planning for a nonmarital child could be problematic for children and families attempting to assert their rights following the nonmarital father’s death. State inheritance law determines how nonmarital children are treated. Generally, the law has developed over time to allow children to inherit from deceased fathers if paternity was established. Nonmarital children also have the right to contest wills, as do all other lawful heirs. They may receive private life insurance or Social Security benefits. Finally, when parents receive other private or government benefits, their nonmarital children may also be entitled to receive payment.
What Happens if a Parent Dies without a Will?
Someone who dies without a will is said to have died intestate. When someone dies intestate, the state determines who inherits based on its default probate laws. When nonmarital children seek to inherit from a deceased intestate parent, they can typically inherit in the same way as children born of a recognized union. Their primary challenge to enjoying this right is the establishment of paternity. The process, as with most laws, differs depending on the state. For example, in California, there are three ways to establish paternity in intestate succession cases:
- The probate court must have had a court order issued when the father was alive.
- Clear and convincing evidence shows that the father acknowledged the child during his lifetime.
- Clear and convincing evidence of the father’s paternity exists, but the father could not acknowledge the child.
If one of these criteria is met in California, the child will be able to inherit intestate.
Other states have more-burdensome requirements. For instance, under Arkansas law, the occurrence of any one of the following six events proves paternity:
- The court established paternity through a court order.
- The father made a written acknowledgment that he is the father.
- The father’s name is on the birth certificate.
- The mother married the father before the child’s birth.
- The mother and father attempted to marry before the child’s birth.
- The man is obligated to support the child as his own under a written court order.
These criteria make it possible for a man to refute paternity.
In other states, however, the law states that, if a man rebuts a presumption that he is a child’s father, only DNA evidence is sufficient to overcome the rebuttal. When the father is deceased, comparing the nonmarital child’s DNA to siblings’ DNA can establish paternity. If the decedent was buried, exhuming the body is rarely done.
In addition, as in California, it is common practice to find that paternity was established when the deceased father acknowledged the child during his life. A signed statement is one of the most concrete forms of acknowledgment. Also, in many states, a child may establish paternity if the father voluntarily allowed his name to be on the child’s birth certificate.
How Can a Nonmarital Child Contest a Will?
As stated above, the ability to challenge a will is generally one of the rights of nonmarital children. The process for challenging a will varies depending on the state. However, as with establishing rights generally, a child who wants to exercise the right to challenge a will must first establish the paternal relationship after legally establishing that the decedent is the father. The timing of a will contest varies because of different default rules and statutes of limitations. Many states allow more time for establishing paternity than for other judicial proceedings.
