No, a legal name change is not required for AstroNumerology-based name suggestions. Name correction focuses on improving the energetic alignment of the name you use in your personal and social interactions.
If a name refinement is recommended, you may choose to use the suggested name in places connected to your identity and communication, such as visiting cards, professional profiles, social media accounts, signatures, or other personal interactions. The decision to adopt any suggestion remains completely personal and should be made with understanding.
