The answer to so many issues dealing with inheritance and probate is "maybe."
If you want to probate the will as a muniment of title, then you can do that yourself. On the other hand, if the will names you as the independent executor, and you want the court to appoint you as independent executor, then you must have a lawyer to probate that will. An independent executor represent the estate and a non-attorney cannot represent others in court. You have to be an attorney to represent others in court. "An executor of an estate serves in a representative capacity of the estate, thereby requiring an attorney to represent the interests of the third-party (the estate) at the outset." 13-17-00555-CV.
