My question involves name change laws in the State of: Idaho.

I'm turning seventeen in a couple of months.

My mother was/is neglectful, abusive, and doesn't make the best choices in men. As in, her past fiancés have sexually and physically abused her children while drunk/high/etc (it's no longer going on, by the way).

Although I've made it a point to keep her out of my life as much as possible, I don't want her to be able to find me. So, if I changed my name after I turn seventeen (with my legal guardian's consent) would she be able to find my location, or contact me because she's my biological mother? Or is there a way I can get those files sealed from her? As far as I know, she has no visitation rights towards me, and no physical custody of me.
