"Magaslaw" is not a recognized word in Tagalog. It seems like a combination of "magasawa" (to be married) and "batas" (law).
To translate the intended meaning, you need to provide more context. For example, if you're trying to say something like "married by law," you could use:
* May asawa sa batas: This translates to "married by law."
* Legal na kasal: This means "legal marriage."
If you can provide more context about the intended meaning of "magaslaw," I can give you a more accurate translation.
