Asset Protection Guide

Helping Family Buy

Assisting your children with a deposit gift, mortgage guarantee, or co-ownership structure is a generous way to help them enter the NZ property market. However, without correct legal shielding, parent assets are exposed to bank liabilities and relationship breakdowns.

Independent Legal Advice (ILA)

Under New Zealand Law Society rules, the same lawyer cannot represent both the child buying the home and the parent acting as a guarantor. This represents a conflict of interest.

The Requirement: Parents acting as guarantors or co-borrowers must obtain an independent certificate of legal advice from a separate, independent law firm to sign bank security papers.

1. Deeds of Gift & Relationship Property Hazards

A Deed of Gift is a document requested by retail banks confirming that deposit funds provided by a parent are a non-refundable gift, not an interest-bearing loan. The bank requires this to ensure the child has no secondary debt that could affect mortgage serviceability.

**The Relationship Property Risk**: Under the New Zealand Relationship Property Act 1976, once a child resides with a partner or spouse in the property for three years, that home becomes a "family home" and is subject to a **50/50 equity split** upon separation.

Without legal safeguards, if the couple separates, your child's partner will inherit half of the deposit you gifted. We help families protect their gifts by drafting **Section 21 Contracting Out Agreements** (pre-nuptial agreements) or structuring the gift as a registered interest-free loan repayable upon sale.

PROTECTING GIFTED DEPOSITS

Instead of a straight gift, parents can document the funds as a **demand loan** using a Deed of Debt:

The loan is interest-free and has no scheduled repayments (satisfying bank serviceability rules).
It is repayable immediately if the child sells the property or separates from their partner.
This pulls the deposit capital out of the relationship property pool, returning it securely to you.

Parent Guarantees & Co-Ownership structures

2. Parent Guarantor Risks

A guarantor guarantees that the borrower will meet their loan repayments. If the child defaults, the bank can demand payment directly from you, potentially forcing the sale of your own home.

**The Safeguard (Limited Guarantees)**: Never sign a standard, unlimited guarantee. We negotiate with lenders to draft a **Limited Guarantee**, capping your liability to a specific dollar amount (e.g. $80,000, representing the deposit gap) rather than the entire mortgage value. Once the child builds up equivalent home equity, the bank releases the guarantee.

3. Co-Ownership & Property Sharing Agreements

If you are co-borrowing or contributing cash in exchange for equity, you should register on the land title as **Tenants in Common** (rather than Joint Tenants) to reflect your actual contribution percentages (e.g., parents 25%, child 75%).

**Mandatory Contract**: You must execute a **Property Sharing Agreement** to govern the partnership, detailing:

- Who pays the mortgage, council rates, and maintenance costs.
- What happens if the child wants to buy out the parents' share.
- A dispute resolution framework and pre-agreed rules for selling the property if one party wants to liquidate.

First-Home Buyer FAQs

A guarantor guarantees the mortgage but does not own the property or reside in it. A co-borrower is registered on the land title as a co-owner and is jointly liable for the mortgage repayments. Banks prefer co-borrowers because it gives them direct recourse, but co-ownership carries higher capital gains tax risks (bright-line rules) for parents.

No. Under KiwiSaver scheme rules, retirement savings can only be withdrawn for your own first home purchase (where you intend to reside in the property). You cannot withdraw KiwiSaver funds to gift to a child or relative for their purchase.

If your child defaults, the bank will issue a mortgage demand notice. If you are a guarantor, the lender can demand payment from you directly. If you cannot pay, the bank has the right to force the sale of the child's property first, and if there is still a shortfall, they can legally target your own home or assets to recover the debt.
