Undivided Share
Full form: UDS
Personal FinanceUndivided Share (UDS) is the proportionate ownership of land that each apartment buyer holds in a multi-storey building. Since land cannot be physically divided flat-by-flat, each owner holds an undivided share proportional to their apartment size. Critical legal concept in south Indian real estate.
In detail
Why UDS matters:n1. Legal ownership: your title is strongest when UDS is clearly mentioned in sale deedn2. Redevelopment: when building is demolished for redevelopment, compensation is proportional to UDSn3. FSI/TDR: UDS determines your entitlement in FSI-linked redevelopmentn4. Resale value: buyers check UDS during due diligencennUDS calculation: If land is 5,000 sqft and there are 20 flats of equal size -- each owner's UDS = 5,000/20 = 250 sqft.nnParticularly important in Chennai, Bangalore, and Hyderabad where land-apartment legal framework is more complex than Maharashtra's MOFA (which handled this differently).
Formula
Real-life example
10-floor complex, 1,000 sqm land, 40 flats (each 100 sqm carpet). Total project carpet area = 4,000 sqm. UDS per flat = 1,000 x (100/4,000) = 25 sqm. This 25 sqm UDS is explicitly mentioned in each flat's sale deed. During a redevelopment 20 years later, each owner receives compensation based on their 25 sqm UDS.
