Are all owners supposed to sign on registry in joint ownership of land

A plot has been purchased in gurgaon jointly by 3 ladies. In the registry signature of buyer is mandatory ? If yes, do all the three ladies need to be there for the registry? If only one or two ladies are signing as buyers on the registry then while selling that property in future the sale deed will need signature of only the ladies which will sign on the registry or signature of all three owners will be required at that time?
