Buying an apartment jointly with a spouse or family member is one of the most common property purchase structures in Medavakkam. A joint purchase can increase the combined loan amount the co-buyers are eligible for, allow each co-owner to claim home-loan tax deductions independently under the applicable income-tax regime, and simplify estate planning. Understanding how joint ownership works legally, what the income-tax rules require, and what registration involves ensures that the structure you choose at booking actually delivers the benefits you expect at the time of filing returns or at any future resale or transfer.

Prestige Medavakkam is a pre-launch gated apartment project by Prestige Group on Medavakkam–Sholinganallur Road. For the home-loan process that typically accompanies a joint purchase, see our home loan and EMI guide. This guide focuses on the legal, tax and administrative aspects specific to buying a flat in two or more names.

Joint Home Purchase at a Glance

The table below covers six aspects of a joint apartment purchase in Medavakkam. All tax-related information reflects general IT Act provisions as publicly available; confirm current limits, regime applicability and individual eligibility with a CA before filing.

Legal Structure and Loan Eligibility

The two most common legal structures for joint property ownership in India are joint tenancy and tenancy in common. In joint tenancy, co-owners hold equal undivided shares and the property automatically passes to the surviving owner on death, without going through succession. In tenancy in common, co-owners hold specified shares (which may be unequal) and each share is independently inheritable and transferable. The sale deed must state which structure applies and, in the case of tenancy in common, the percentage share each co-owner holds. If the deed is silent, disputes about the intended structure can arise later, particularly when contributions to the purchase price were unequal. A property lawyer can advise on which structure fits your situation before the deed is drafted.

On loan eligibility, the lender calculates the maximum eligible amount based on the combined monthly net income of all co-borrowers, after subtracting existing EMI obligations. Adding a working spouse as a co-borrower is one of the most straightforward ways for a buyer in Medavakkam to increase the eligible loan amount when the unit price exceeds what one income alone can support. Each co-borrower's credit score also affects the interest rate offered; if one co-borrower has a lower score, it can affect the rate even if the other has excellent credit. Check both credit scores before applying. Confirm the combined eligible amount and rate with the lender directly; do not rely on online calculators alone, since lenders apply their own internal credit policies that online tools do not replicate.

Bottom line: State the ownership type and share clearly in the sale deed; confirm combined loan eligibility and both co-borrowers' credit scores with the lender before selecting the unit.

Tax Deductions for Co-Owners and NRI Co-Buyers

The home-loan tax benefit available to joint buyers is one of the most frequently cited reasons for structuring a purchase jointly, but it comes with conditions that many buyers misunderstand. Under the old income-tax regime, each co-borrower who is also a co-owner can claim a deduction of up to ₹1.5 L per financial year on the principal repaid under Section 80C, and up to ₹2 L per financial year on the interest paid under Section 24(b). These limits apply per co-borrower, not to the total loan, meaning two co-borrowers together can claim up to ₹3 L on principal and ₹4 L on interest in a single year. The deduction each person claims must be in proportion to their actual ownership share and their actual loan share; it cannot be claimed in full by one co-borrower if the other is on record as a co-owner but not as a co-borrower. Our home loan tax benefits guide covers all four deduction heads (80C, 24(b), 80EEA and joint-loan benefits) in detail.

Critically, none of these deductions are available under the new income-tax regime, which has been the default since FY 2024-25. Buyers who opt for the new regime (or who do not actively opt into the old regime at the time of filing) will not be able to claim Section 80C or Section 24(b) deductions on their home loan. If maximising home-loan deductions is a priority, confirm the regime choice and the deduction eligibility with your CA before booking, not after registration. For NRI co-buyers, confirm the FEMA-compliant account routing, PoA requirements and any specific lender conditions with your bank and a CA; our NRI guide to buying property covers the full process for NRI and OCI purchasers in Medavakkam.

Bottom line: Each co-borrower can claim home-loan deductions in proportion to their share under the old tax regime only; confirm regime choice, eligibility and proportions with your CA before filing.

Registration, Stamp Duty and Society Records

Joint registration is straightforward in Tamil Nadu: the sale deed lists all co-owners by name and their respective shares (or records the ownership as joint tenancy), and is registered at the sub-registrar's office with all parties present or represented by a valid Power of Attorney. The stamp duty and registration fee are calculated on the transaction value (or guideline value, whichever is higher) and do not reduce because there are multiple buyers; the total cost is the same as a single-owner registration of the same property. Our stamp duty and registration charges guide covers the current-rate framework and the registration process in detail; confirm exact rates with the sub-registrar at the time of registration as rates are subject to revision.

After registration, update the builder's allotment records and, once the society is formed, the RWA's member records to reflect both co-owners' names. This matters for maintenance billing (to whom the invoice is addressed and whose name appears in arrears records) and for any future resale or transfer, where a buyer or their bank will ask to see the title confirmed in both names consistently across the allotment letter, sale agreement, sale deed and society records. A discrepancy in name spellings across documents is one of the most common title-chain issues in joint purchases; check the spelling of both co-owners' names carefully on every document from the booking form onwards and flag any discrepancy immediately to the builder or legal team.

Bottom line: Stamp duty does not reduce for co-ownership; ensure both co-owners' names are spelled consistently across every document from booking to registration to society records.

Conclusion

A joint home purchase in Medavakkam offers three practical advantages: greater combined loan eligibility, the ability for each co-borrower to claim home-loan deductions independently under the old tax regime, and a simpler inheritance structure compared to a sole-owner purchase. The structure works best when the ownership type and share are documented clearly in the sale deed, both co-owners are registered as co-borrowers on the loan if deductions are the goal, and the name spelling is checked for consistency across every document from booking to registration. The income-tax regime question is critical and non-obvious: buyers who default into the new regime without an active choice will not benefit from the deductions that often motivate a joint purchase in the first place. Confirm the regime, the share proportions and the deduction eligibility with your CA early in the process, not at the time of filing.
