Do Two Last Names Have to Be Hyphenated?
A person will take the (first) surname of their father, followed by the (first) surname of their mother (i.e. their maternal grandfather's surname). The double surname itself is not heritable. These names are combined without hyphen (but optionally combined using y "and").

Similarly, you may ask, can you legally have two last names without a hyphen?

Answer: As long as you can submit an original or certified copy of the marriage certificate documenting the use of two last names without the hyphen, then you can have them both on your passport.

Beside above, how do you write two last names? The two surnames are referred as the first apellido and the second apellido. Also, we refer to our first name by just name, and the middle name is referred as second name instead of middle.

In this way, can I legally have two last names?

It is extremely confusing for legal purposes to use two last names interchangeably. I recommend that you either legally change your name to either your married last name or a hyphenated last name. You can also move your maiden last name to your middle name and make your married last name your last name legally.

Why are last names hyphenated?

Hyphenating your last name allows you to maintain your identity while also accepting your spouse's. Your friends, colleagues, and clients won't lose track of you after your name change. Keeps your professional identity. Hyphenating can be great if you use your current last name for professional reasons.

Child's Name
Unmarried couples typically have two different last names. Unmarried couples aren't required to give their child a specific surname upon birth. The child may carry the mother's surname, father's surname or a hyphenated surname. The name the couple chooses then appears on the newborn's birth certificate.

Which name goes first in hyphenated last name?

Generally, there are no set rules when it comes to deciding exactly how your hyphenated last name will read. You can go the “traditional” route and list your maiden name first, or you could choose to list your new last name first, followed by your maiden last name.
