Can a foreigner change their name and surname in Spain?

In Spain, foreigners cannot legally change their names or surnames. The only way to do so is by becoming a Spanish citizen, which can be achieved after 10 years of residency for most countries or shorter periods for specific nationalities. Changing surnames for grammar or phonetics reasons is allowed, but must belong to a vernacular language and be proven with documentation. Marriage or divorce also provide options for changing surnames in Spain.
