Buying with a partner, a mate or family? Talk about who owns what before signing, including what each person's deposit is meant to buy.
The main difference
"Tenant" here is about ownership. It doesn't mean you're renting.
| Decision | Joint tenants | Tenants in common |
|---|---|---|
| Ownership shares | No defined individual shares | Defined shares, equal or unequal |
| If an owner dies | Their interest generally passes to the surviving owners through survivorship | Their share generally passes through their estate |
| Unequal ownership | Not as separate percentages within the joint tenancy | Possible, such as 70/30 |
| Who might consider it | Co-buyers whose estate plans favour survivorship | Co-buyers who want defined shares or their share to pass through their estate |
The main difference
Ownership shares
- Joint tenants
- No defined individual shares
- Tenants in common
- Defined shares, equal or unequal
If an owner dies
- Joint tenants
- Their interest generally passes to the surviving owners through survivorship
- Tenants in common
- Their share generally passes through their estate
Unequal ownership
- Joint tenants
- Not as separate percentages within the joint tenancy
- Tenants in common
- Possible, such as 70/30
Who might consider it
- Joint tenants
- Co-buyers whose estate plans favour survivorship
- Tenants in common
- Co-buyers who want defined shares or their share to pass through their estate
With joint tenancy, survivorship applies regardless of the deceased owner's will. Couples, friends and family can need either ownership structure. Your relationship alone doesn't decide which one fits.
Blended families need particular estate-planning care. If you want children from an earlier relationship to receive your interest, have your solicitor explain how survivorship would affect that plan. Don't assume a will can direct a joint-tenancy interest away from the surviving owner.
A smaller share doesn't mean a smaller debt
A 30% share doesn't limit the bank to 30% of a joint debt. Your loan and guarantee documents decide what you owe. Joint borrowers can be responsible for the whole debt if the other stops paying.
We can check with suitable lenders who must be a borrower and who must give security. Your solicitor can explain the legal implications and any independent advice required. Don't assume you can own a share without mortgage exposure.
Check the lender accepts how you're related, not just your shares. With ubank, a qualifying joint application can include a spouse or de facto partner who lives with you or will after settlement, but not a sibling or parent. That restriction is specific to ubank, not all family purchases.
For a first home loan or 5% deposit scheme purchase, the applicants and ownership need checking too. Unequal ownership isn't a workaround for a scheme or duty rule. Our low deposit loan guide covers other small-deposit options.
Five questions for every buyer
- How much are we each putting in?
- Is that meant to decide ownership?
- Who pays repayments and running costs?
- What happens if someone dies?
- What happens if one of us needs to sell or can't pay?
A couple with children from earlier relationships may want something different from siblings buying a first unit. Neither structure is best for everyone. Check wills, insurance and tax alongside the ownership plan.
When someone wants out
Ask your solicitor about a co-ownership agreement: valuation and buyout steps, sale triggers, unpaid expenses, repairs, disputes and exits.
An agreement between owners doesn't make the bank release a borrower. A buyout can mean the lender reassesses affordability, and the remaining owner needs cash for the departing owner.
If nobody can refinance, selling may be the practical answer. Our refinance guide covers the lending costs to compare.
Ownership percentages don't guarantee a family law outcome after separation. Get advice instead of assuming the title answers every future question.
Changing it later
It may be possible, but get fresh advice before acting. Transfers can involve duty, registration, legal costs, lender consent and tax. Being married doesn't make every transfer free.
If you already own the home and want to add a partner, see our adding your partner to the title guide.
Ask your solicitor what changing from joint tenants to tenants in common would mean for your documents and estate plan. Don't assume a transfer will be exempt from duty without having your circumstances checked.
An unequal deposit with equal repayments
Here's a hypothetical example, not a recommended ownership setup. Two siblings put in $120,000 and $60,000 towards buying costs and a deposit, and plan to share future repayments equally.
A 2:1 split of that cash doesn't automatically tell them what the title shares should be. Do they want unequal shares permanently, the extra paid back when they sell, or something else?
Their solicitor can write down what they agree, including how renovations or uneven repayments will count. It's a legal and planning decision, not a ratio to copy.
Quick answers
Check the ownership plan against the loan
Tell us who's buying, what each person is contributing and the plan. Speak to a Brisbane mortgage broker while your solicitor checks the legal structure. For a rental purchase, an investment property mortgage broker can check the lending side of the same plan.
Broker view on buying together
We start with the people on the title, the people applying for the loan and how each deposit is funded. Tell us about gifts, family loans and any plan for one owner to contribute less to repayments. Those details need to match the application and your legal agreement.
Separate loan splits may help track repayments, but don't assume they cap each person's liability. Ask your solicitor to explain the obligations in the actual loan and security documents.
