I want to change my surname

In Republic vs. Hernandez[7], we have recognized inter alia, the following as sufficient grounds to warrant a change of name: (a) when the name is ridiculous, dishonorable or extremely difficult to write or pronounce; (b) when the change is a legal consequence of legitimation or adoption; (c) when the change will avoid confusion; (d) when one has continuously used and been known since childhood by a Filipino name and was unaware of alien parentage; (e) when the change is based on a sincere desire to adopt a Filipino name to erase signs of former alienage, all in good faith and without prejudice to anybody; and (f) when the surname causes embarrassment and there is no showing that the desired change of name was for a fraudulent purpose, or that the change of name would prejudice public interest.
