Yes, you can do so by filing for partition in the nearest district court. Or, if all members consent to such partition, you can apply for a partition deed (which needs to be registered at the Registrar's office to have a binding effect.) Each of you will thus be granted with absolute ownership over your respective shares of the plot. (i.e. 1/4 each if there are only 4 brothers and no other possible beneficiaries like mother or sister(s), this being joint family property.)
After the partition is effected, each of you will have absolute right of ownership over your share, you can thus sell, gift mortgage etc your share as per your discretion.
