This is something you will have to call into Square customer Service and see what they say as this isn't anything that can be helped here on this public forum. I'm not sure if this specific kind of loan can even be legally transfered in its terms and may need to be paid off, but that's just me guessing and you'll have to call in and see.
You'll need your customer code to call. Follow the instructions below on how to get it.
