Housing

I have a 6 bed property in Barbados that i am looking to sell this year subject to redecoration. I am considering selling the property in two parts ie top flat and bottom flat instead of one whole 6 bed property. Can anyone direct me as to what the process would be to legally seperate the 2 properties and how long this process would take. Also which govt or regional office do i approach/contact.

Any advice would be appreciated.

Thanks you.
