My daughter and I both signed a rental agreement I want to move but she doesnt how can i get out of the rental agreement obligation free

Unfortunately, unless your landlord will agree to release you from the lease, you are both jointly and severally liable for the lease payment.  Which means that you are both responsible for the entirety of the lease amount.  If you move, hopefully, your daughter can pay the rent on her own.  If she doesn't she will likely face eviction.   Good Luck
