It’s not an unusual situation, but it does have to be addressed. It’s pretty common to include additional identifiers in the documents. For example, let’s say the will says I leave my house to my daughter Samantha Roberts. If Samantha gets married and changes her last name, it can be reasonably assumed that she can be identified. In some cases, the document may be able to stay the same.
In other instances, the difference will be incorporated through the use of the acronym AKA—Also Known As. That is used when a person’s name is different for some reason. If the deed to a home says Mary Green, but the person’s real name is Mary G. Jones, the term used will be Mary Green A/K/A Mary G. Jones.
Sometimes when a person’s name has changed completely, another acronym is use: N/K/A, or Now Known As. For example, if Jessica A. Gordon marries or divorces and changes her name to Jessica A. Jones, the phrase Jessica A. Gordon N/K/A Jessica A. Jones would be used.
However, in the situation noted above, most attorneys to want to have the documents changed to reflect the name change. First, there are two people in the family with similar names. It is possible that someone could claim that the person wished to name the other person. It may not be a strong case, but challenges have been made over smaller matters.
Second is that the document being discussed is a healthcare designation. Usually when a health care power of attorney form is being used, it’s in an emergency. Would a doctor make a daughter prove that she is who she says she is? It seems unlikely, but the risk of something like that happening is too great. It is much easier to simply have the document updated.
In most matters, when there is a name change, it’s not a big deal. However, in estate planning documents, where there are risks about being able to make decisions in a timely manner or to mitigate the possibility of an estate challenge, a name change to update documents is an ounce of prevention worth a pound of trouble in the future.
