Helping your child with a house deposit: what to agree before money moves

Editorial review: Jim Stewart Reviewed 9 July 2026 General Australian information

Helping an adult child with a house deposit can look like one bank transfer. It is usually more than that.

It may affect what the child tells a lender, what siblings expect later, what Centrelink counts, what the ATO may need to know, and what happens if a relationship breaks down or a parent dies.

This guide does not tell you whether to gift, lend, guarantee, co-own, or wait. It helps the family slow down and write down what everyone thinks is happening before money moves.

If you are still deciding whether the help is a gift or a loan, start with our gifting vs lending guide. If you want the broader map, read our Bank of Mum and Dad guide.

First, name the kind of help

Before the deposit deadline takes over, describe the support in plain English.

Common shapes include:

The label matters because different people may ask different questions later. A lender may ask what the money is. Centrelink may ask whether a gift affects a payment. A sibling or executor may ask whether the support was meant to be equalised in the estate. A lawyer may ask what evidence existed at the time.

The pre-transfer checklist

Before money moves, try to answer these questions in writing.

Amount and timing

Purpose

Gift or repayment expectation

If the answer is “we will sort that out later”, that is the point to slow down.

Who is involved

What the lender or broker has been told

If the child is borrowing, the lender or broker may ask where the deposit came from and whether the money needs to be repaid.

Some practitioner sources note that lenders may ask parents to declare that funds are a gift and not a repayable loan. Treat that as a lender-evidence question, not a universal rule. The child can ask the broker or lender what evidence is required for the specific application.

The important point is consistency. If the family calls the transfer a gift to the lender but privately expects repayment, that mismatch can create later problems.

If the help is a gift

A gift is usually simpler than a loan, but it still needs a record.

Questions to answer:

Services Australia says a gift can include transferring income or assets for less than their value, and gifted income or assets may still count in income and assets tests.

Services Australia also lists gifting free areas of $10,000 in one financial year and $30,000 over 5 financial years, with no more than $10,000 in a single financial year. It says gifts above the free areas can be counted in the assets test and deemed in the income test for 5 years from the gift date.

These thresholds are date-sensitive. Check the Services Australia page before relying on them, especially before approval or if the parent receives or may apply for a payment.

If the help is a loan

A family loan needs more than a shared understanding. Practitioner sources consistently warn that parent-to-child transfers can be disputed later if the evidence is unclear.

A lawyer may ask about:

This is not a do-it-yourself contract checklist. It is a list of topics to raise with a lawyer before the money moves.

No document can guarantee how a later dispute will be resolved. The aim is to reduce ambiguity and make the family’s intention clear at the time.

If the help is a guarantee

A guarantee is different from giving deposit money. The parent may not transfer cash, but they may take on serious risk.

Moneysmart says a guarantor may have to repay the whole loan plus interest if the borrower cannot repay, and a secured asset such as a home may be at risk.

Before agreeing to guarantee a loan, ask the lender or broker:

A guarantee belongs in its own advice conversation. It is not just another way to describe deposit help.

If the parent may co-own or transfer property

Co-ownership, putting a parent on title, selling below market value, or transferring property between family members can create tax, duty, estate, lending, family-law, and exit issues.

The ATO says that if someone sells, transfers, or gifts property to family or friends for less than it is worth, they may be treated as if they received market value for capital gains tax purposes.

That source is about property transfers, not ordinary cash deposit help. If property, title, trusts, companies, or forgiven debts are involved, speak to an accountant or tax adviser as well as a lawyer.

Questions to raise before co-owning include:

Siblings, estate records, and family expectations

A deposit contribution can become an estate issue later, even if everyone is calm today.

Useful questions for the parent and their lawyer:

Do not rely on memory for this. Families forget dates, amounts, and intentions. A short record now can save a much larger argument later.

Who to talk to before money moves

The right professional depends on the structure.

For now, start with one sentence:

We are thinking about helping with [amount or support type], and we currently think it is a [gift, loan, guarantee, co-ownership arrangement, or other support].

If that sentence is hard to complete, pause there. The structure is not clear enough yet.
