Revision: corrected the previous 99/1 eligibility and stamp duty claims, and removed unverifiable personal stories.
Joint tenancy, commonly called 長命契 in Hong Kong, and tenancy in common differ mainly in what happens to an owner's interest on death. Neither arrangement guarantees tax savings or first-time buyer eligibility.
What is joint tenancy?
Joint tenants hold the property together without separate individual shares. CLIC explains that when a joint tenant dies, the interest generally passes to the surviving joint tenants through the right of survivorship rather than under the deceased's will.
The ownership position at death matters. Ask a solicitor to inspect the deeds and check whether the joint tenancy has been severed or another arrangement affects the title. Buying a home “jointly” does not, by itself, identify the legal ownership form.
How does tenancy in common differ?
Tenants in common have distinct interests, which may be equal or unequal. A deceased owner's interest generally forms part of the estate and follows a valid will or the applicable intestacy rules. The other co-owner does not automatically inherit it just because they own the property together.
- Ownership: joint tenancy has no separate individual shares; tenancy in common specifies each interest.
- Death: survivorship is central to joint tenancy; a tenant in common's interest enters the estate process.
- Wills: check both the ownership form and the will if an interest is intended for particular beneficiaries.
- Transfers: deeds, other owners' rights and mortgage conditions still need checking before a sale or change of ownership.
Does a 99/1 split preserve first-time buyer status?
A 1% interest does not establish eligibility. Mortgage insurance and subsidised housing schemes can use different definitions. Check the scheme's current rules against the applicant's actual property interests. A small ownership percentage also does not establish an equivalent limit on mortgage liability.
Buyer's Stamp Duty (BSD), New Residential Stamp Duty (NRSD) and Special Stamp Duty (SSD) were abolished for relevant residential sale or transfer instruments executed on or after 28 February 2024. Old 15% rates are not a sound basis for promoting a 99/1 arrangement. Ordinary ad valorem stamp duty still depends on the transaction and current rules.
Questions for the solicitor and bank
- Record contributions, repayments and intended beneficiaries; distinguish payment arrangements from legal title.
- Agree what should happen on death, repayment difficulties or an owner's decision to leave.
- Before changing an existing joint tenancy, ask about the documents, notices, registration, tax treatment and lender consent required.
- Request an itemised quotation covering professional fees and disbursements. Check valuation, duty and finance separately for a transfer or buyout.
- Review the final ownership arrangement alongside the will.
Frequently asked questions
Is joint tenancy always suitable for married couples?
No. Survivorship may support an intention to benefit a surviving spouse. An intention to leave an interest to children or others needs a review of the title and estate arrangements. There is no single suitable form for every family.
Can a joint tenancy become a tenancy in common?
Severance and changes to the holding arrangement require legal advice on the deeds and circumstances. Check lender requirements for mortgaged property; simply writing down percentages does not complete the process.
Can a tenant in common sell a share at any time?
Do not assume an unrestricted exit. Legal documents, financing and transaction conditions affect a proposed transfer. Confirm the buyer, costs and arrangements with other owners before committing.
