In Spain you can also change your given name without much problem (though it has all the inconveniences of bureaucratic processes, fees, etc) It is not possible to change from a male to a female name or viceversa (unless you are legally changing your gender, which has its own, more complicated process). There are unisex names, but are pretty uncommon in Spanish, though I guess using a foreign name could be a trick in these cases. (Note: People have two surnames in Spanish, the first one inherited normally from the father, and the second from the mother [1]) There are some cases where surnames can be changed, but they follow some rules and it's not very flexible. For example, is not uncommon to join surnames if they are "famous enough", so they will be inherited as one (keeping the reference to the famous ancestor). In case someone is curious, here is a link (in Spanish) showing the process to change name ad surnames [2] [1] http://en.wikipedia.org/wiki/Spanish_naming_customs http://en.wikipedia.org/wiki/Spanish_naming_customs [2] http://www.mjusticia.gob.es/cs/Satellite/es/1200666550200/Tramite_C/1214483962185/Detalle.html http://www.mjusticia.gob.es/cs/Satellite/es/1200666550200/Tr...
