Hello Aspirant,
No you will not be eligible for domicile certificate of Jharkhand because you have only completed class 12th from Jharkhand and also you don't have any permanent property in Jharkhand so you do not deserve the domicile of Jharkhand. If you are a permanent resident of Bihar then you must be having domicile of Bihar.
I hope this information helps you.
Good Luck!!
