The ruling on naming a child with a name other than the one he was given

My mother gave birth to a daughter and put a name for her in the register, but we call her by another name at home. We heard that this is forbidden. Is what was told to us correct?
Answer: It is recommended that she be called by the name she was given, and not by any other name. A believer should adhere to the things that have been established so that matters are not confused. She should be called by her known name, just as she is called by her father’s known name: [Al-Ahzab: 5]. Do not give her another name that causes confusion and by which she is not recognized. This is because names were established for identification and for regulating matters, buying and selling, and all other rights, which are all regulated by names. If you use other names that are not the official ones, it will lead to confusion and problems. Therefore, that is not recommended. Rather, you should call her by her known, official name, the one by which she is recognized, whether it is in her passport, if she has one, or in her records, if she has records, or in her properties, if she has properties. The point is that she should be called by her known, official name. Yes.
