As far as I know, if the person you are going to follow does not give consent to this, then you can end up in jail.

I have boost mobile and I need to know how.to track the location on my husband's phone without him finding out. I don't have his phone. I have his gmail address but I'm sure he.changed his password. I am on his recovery email address and I have his recovery phone number. I don't think he keep the location setting on and my location is off but the apps that need permission. I'm having lots of problems with a lot of things and this would allow me to get a good start without him finding out. Please let me know when you can.
