Does clear nail polish have an expiration date my mom had this nali polish called Magic Formula Nail and Cuticle Treatment for more than 10 years just wondering?

Yes, it's two years after the bottle was opened. You can try this stuff; if you put it on and it's real thick and hard to brush out, throw it away because it's no good anymore. (They sell nail polish thinner, but once nail polish starts to get thick, it's toast.)
