Hey Ashok.

No, you cannot take admission in Delhi University for evening classes of LLB. As from the batch of 2017-18 the evening batches of DU for LLB has been scrapped. Earlier DU had an evening law course but not it has been scraped after the directions for the Bar council of India owing to infrastructural and intake issues. Now there are only regular morning Courses offered for LLB, though Law Centre 2 has been allowed to conduct classes from 2:30-7. You can see if it suits you.
You can use the link given below in case you need any other information.
