Property Registration - Partners

I have purchased a land along with my two partners and build a 4 storey house. I am using one floor and 3 floors have been sold out.

I want to become owner of one floor by settling the share of my partners. They are happy with this plan. What type of registration is required so that I become ownership of the floor and enable me to sell the same at later time without involving my partners?

Thanks in advance for your answers.
