How to buy out a partner's share of the home loan.

Separating and keeping the home usually means solving two jobs at once: agreeing on the property settlement and proving the remaining borrower can refinance the loan in their own name.

1. Value the propertyStart with a realistic current value or formal valuation.
2. Confirm the loanUse the actual payout figure, not just the balance in the app.
3. Agree the splitLegal advice helps turn the agreement into usable paperwork.
4. RefinanceThe lender must be comfortable with the new loan and sole borrower.

Plan the next move

Keep the home decision grounded in the numbers.

A property settlement can be emotional. A clear refinance plan helps you understand the valuation, payout figure, borrowing capacity and loan structure before committing to the next step.

The simple version

What does buying out a partner mean?

A partner buyout usually means one person keeps the property, refinances the mortgage into their own name and pays the other person an agreed amount for their share of equity.

That can sound simple, but lenders assess it like a real refinance. They look at income, expenses, other debts, credit conduct, the property value and the total loan needed after the payout, fees and any settlement costs.

Payout formula

How the buyout amount is commonly estimated

The starting point is usually the property's current value minus the debt and agreed costs. The remaining equity is then divided according to the settlement agreement.

(Property value - loan payout - agreed sale or settlement costs) x partner share = estimated buyout Example: $800,000 value - $500,000 loan - $10,000 costs = $290,000 equity. If the outgoing partner receives 50%, the buyout is $145,000.

This is not a legal entitlement calculator. Contributions, future needs, parenting arrangements, superannuation, other debts and negotiated settlement terms can all change the final number.

Process

The refinance path after separation

The smoothest pathway is usually legal advice and lending advice moving together, so the agreement matches what the lender can actually approve.

1

Confirm the settlement pathway

Speak with a family lawyer about consent orders, a binding financial agreement or the right structure for your situation.

2

Check borrowing capacity early

Before signing final terms, test whether the remaining borrower can service the refinanced loan and partner payout.

3

Order a valuation

The lender may use its own valuation, which can differ from an agent appraisal or the figure used in negotiations.

4

Apply for the refinance

The new loan may need to pay out the old mortgage, pay the outgoing partner and cover approved fees or costs.

5

Transfer ownership

Your solicitor or conveyancer handles the title transfer, discharge and settlement documents with the lender.

6

Reset the loan structure

After settlement, review offset, redraw, fixed or variable splits and repayment buffers for your new single-income position.

Important traps

Do not assume the mortgage or duty position is automatic

  • A private agreement between former partners does not automatically remove a borrower from the existing loan.
  • Transfer duty exemptions after relationship breakdown vary by state and depend on the documents, timing and property ownership.
  • Keeping the home may be emotionally important, but the loan still needs to be comfortable on the remaining borrower's income.
  • Missed repayments during separation can affect both borrowers' credit history while both names remain on the loan.
