Buying with another person combines ownership, borrowing and day-to-day arrangements. Agree on those matters before the purchase rather than assuming a shared deposit resolves them.
Choose and document the ownership
Ask your solicitor or conveyancer to explain joint tenancy and tenancy in common. An ownership share does not automatically allocate a floor, bedroom or measured portion of the home. Record how the home will be used separately from how it is owned.
Understand the borrowing commitment
A joint loan can expose a borrower to responsibility for the whole debt, not only a privately agreed share. Ask the lender and an independent legal adviser to explain the contract. An agreement between owners does not automatically limit the lender’s rights.
Set arrangements for expenses
Record contributions to the purchase, repayments, rates, insurance and repairs. Agree how decisions and unexpected costs will be handled. Keep evidence of payments and review the arrangements when circumstances change.
Plan for an exit or dispute
Discuss sale, a proposed buyout, missed payments, separation and death before committing. Work through legal and finance requirements rather than assuming someone can simply transfer their share whenever they wish. Shared buying still requires lender approval and a sustainable budget.
