My 15yo Sister Has Been Dumped With Me. Can I Get In Trouble If She Lives With Me For A Little While? Pa + Md, Usa.

My mom lives in Maryland. I live an hour away in Pennsylvania. I am over 21, have a house and a good job.

Our dad is under investigation for child abuse and has been told not to make contact with my little sister.

Our mom HATES my little sister (who is 15, let's call her Jane) because Jane has depression and self harms and has multiple suicide attempts. Yesterday she said "Jane has to go live with @Abigails_Crafty. I can't handle her rudeness."

Jane slept at my place last night. She's homeschooled, so will not miss school.

I'm calling my job-provided lawyer on Monday.

Can I get in legal trouble for having Jane live with me for the next few days?

Our dad has been told not to make contact with Jane: do I still need his permission to have her stay with me?
