If you own a plot or an old house in a growing part of Chennai, developers may have approached you with a joint development offer. Instead of selling the land, you contribute it to a project; the developer pays for approvals and construction; and you receive a share of the finished flats or the sale proceeds.
Done well, it's one of the best ways to unlock land value. Done badly, it can leave your land locked in a stalled project for years. This guide explains how JDAs work and what protects you.
How a joint development works
- You contribute the land, with clear title.
- The developer contributes design, approvals, construction finance and marketing.
- You receive an agreed share of the project, usually flats (area sharing) or money (revenue sharing).
- The developer sells the remaining units to recover costs and earn a profit.
Area sharing vs revenue sharing
| Area sharing | Revenue sharing | |
|---|---|---|
| What you get | Specific flats or built-up area | A percentage of sale proceeds |
| Best for | Owners who want to live in or rent out flats | Owners who want cash |
| Main risk | Construction quality and delays | Sale prices and slow sales |
| What to fix in the JDA | Which flats are yours, by floor and facing | How proceeds are tracked and paid |
What share should a landowner get?
There's no fixed ratio. Your share depends on the land's value, the road width and permitted FSI (which decide how much can be built), approval costs, and the developer's construction and selling costs. Prime locations with wide roads command a better landowner share than interior plots.
Get offers from more than one developer, and compare them on the same basis: your share of saleable area, the specifications, the timeline and the deposit. Don't compare headline percentages alone.
Clauses that protect you
- Refundable security deposit: paid to you at signing and adjusted or refunded at handover. It shows the developer's commitment.
- Identified share: your flats listed by number, floor and facing in a schedule to the agreement.
- Timelines with penalties: dates for approvals, start and completion, with compensation for delay.
- Limited power of attorney: the PoA should let the developer do only what the project needs, ideally only for the developer's share of units.
- Specifications: materials and brands for your flats, the same as or better than the developer's units.
- Exit clause: what happens if approvals aren't obtained or the developer abandons the project.
- Registration: a registered agreement gives you far stronger protection than an unregistered MoU.
Practice on registering JDAs has varied between Sub-Registrar Offices in Tamil Nadu, and some offices now ask for a registered JDA before they'll register flat sales. Your lawyer should confirm the current requirement and charges before signing.
Tax: when do you pay?
Giving land for development is treated as a transfer for capital gains purposes. For individual landowners under a registered JDA, the gains have generally been taxed in the year the project receives its completion certificate, not when the agreement is signed. Tax rules change, so plan this with your chartered accountant before you sign.
Choosing the right developer
- Visit their completed projects and talk to residents and other landowners they've partnered with.
- Check their TNRERA registrations and any complaints. See how to check TNRERA registration.
- Ask how the project will be financed. A developer relying entirely on pre-sales is riskier.
- Check whether they have too many projects running at once.
Before you approach developers
- Put your title documents in order: patta in your name, a recent EC and the full chain of parent deeds. See our land documents checklist.
- If the land is family-owned, get every co-owner's agreement in writing.
- Know your road width and plot dimensions. They drive what can be built.
