How to Prepare for a Section 21A Agreement Without Paying a Lawyer for Prep Work in NZ

The Short Answer

You can't avoid a lawyer entirely for a Section 21A agreement — the Property (Relationships) Act 1976 makes independent legal advice and certification mandatory for both parties. But you can avoid paying $250–$600 an hour for the administrative preparation that precedes the drafting stage. That preparation work — inventorying assets, classifying property, calculating KiwiSaver splits, tracing separate property, and assembling a financial brief — is where most of the billable hours accumulate, and it's work you can do yourself with the right framework.

The goal isn't to bypass your lawyer. It's to walk into their office with a complete, organised brief so they spend their time on legal advice and certification instead of sorting through your bank statements.

What a Section 21A Agreement Actually Requires

Section 21F of the PRA sets out specific legal requirements for a binding relationship property agreement:

1. The agreement must be in writing
2. Both parties must receive independent legal advice from separate qualified lawyers
3. Each lawyer must certify that they explained the effect and implications of the agreement to their client
4. The lawyers must witness the signatures

If any of these requirements aren't met, the agreement is void. No template, guide, or online service can bypass this. The question is how much time — and at what rate — your lawyer needs to spend before they're comfortable certifying.

The Preparation Work You Can Do Yourself

The hours between "we've decided to separate" and "the lawyer drafts our agreement" typically involve five categories of work. All five can be done without a lawyer.

1. Establish and document the separation date. The separation date determines which assets fall into the relationship property pool and which don't. Write down the date you and your partner began living separately (or, if you separated under the same roof, the date your relationship effectively ended). Keep evidence — texts, emails, the date one of you moved to a spare room. If you're using the same-roof separation option, document the separate living arrangements.

2. Inventory every asset and liability. Pull statements for every bank account, credit card, personal loan, mortgage, KiwiSaver account, investment portfolio, insurance policy, vehicle, and real property. Record the current value and the value at the separation date. This is pure administrative work — gathering documents, logging numbers, filling in a worksheet.

3. Classify each item as relationship property or separate property. Under the PRA, relationship property includes the family home, family chattels, and property acquired during the relationship. Separate property includes inheritances, gifts from third parties, and property owned before the relationship — unless it's been intermingled. Classification requires understanding the PRA's categories, but it's a factual exercise based on when and how each asset was acquired.

4. Calculate the relationship portion of KiwiSaver and other retirement accounts. KiwiSaver balances accumulated during the relationship are relationship property. Pre-relationship balances are separate property. The calculation requires obtaining your opening balance at the start of the relationship, your balance at the separation date, and isolating the growth attributable to the relationship period. It's arithmetic, not legal analysis.

5. Draft a settlement proposal. Once you've inventoried, classified, and valued everything, you can draft a proposed division. This isn't a legal document — it's a structured summary of who gets what, based on your understanding of the PRA's equal-sharing rule. Your lawyer reviews this proposal, identifies any legal issues, and drafts the formal agreement.

What This Saves

Family lawyers bill between $250 and $600 per hour in New Zealand. If you walk in unprepared, your lawyer spends the first several hours on administrative work: asking you to gather documents, waiting for you to return with incomplete information, sorting through statements, and calculating values. At $350 an hour, ten hours of this costs $3,500.

If you walk in with a complete financial brief — inventory done, classification attempted, KiwiSaver calculated, settlement proposal drafted — your lawyer can skip the administrative phase and focus on reviewing your work, flagging legal issues, providing advice on edge cases, and drafting the agreement. That might take three to four hours instead of ten. The savings are $2,000–$2,500.

The New Zealand Divorce Financial Split & Asset Division Guide provides the worksheets for every step: Asset and Debt Inventory, KiwiSaver Split Calculator, Family Home Buyout Worksheet, Separate Property Tracing Worksheet, Financial Disclosure Checklist, and Settlement Proposal Template. Each worksheet is designed to produce the kind of organised output a lawyer can review efficiently.

The Three Mistakes That Waste Lawyer Time

Even people who try to prepare on their own often make mistakes that undermine their effort:

Incomplete disclosure. Missing a single joint credit card, an old term deposit, or a KiwiSaver account from a previous employer means your lawyer has to send you back to gather more information. Use a systematic checklist that covers every category — bank accounts, credit cards, loans, mortgages, KiwiSaver (both partners), investments, vehicles, real property, insurance policies with cash value, business interests, debts owed to you, and debts you owe.

Wrong valuation dates. The separation date is used conventionally for cash accounts and KiwiSaver to exclude post-separation contributions, while the statutory default can use the date of settlement or hearing for real estate and investments. Getting the dates wrong means your lawyer has to redo the calculations. A good preparation framework specifies which valuation date applies to each asset category.

Confusing classification. The most common error is assuming an inheritance received during the relationship is automatically separate property. Under Section 10 of the PRA, inherited property remains separate only if it hasn't been intermingled with relationship property. If you deposited an inheritance into a joint account, it may have lost its separate status. Your lawyer needs to assess this — but you can flag the issue and provide the documentation trail in advance rather than discovering it mid-consultation.

Who This Approach Is For

• Couples who've agreed on the broad terms of their property split and need to formalise it through a Section 21A agreement
• Anyone who wants to minimise legal costs by doing the administrative preparation themselves
• Partners with straightforward asset pools — family home, KiwiSaver, joint accounts, some debt — who don't need a lawyer to identify what they own
• People who want to understand the PRA framework before meeting a lawyer, so they can ask informed questions and make better decisions

Who This Approach Is NOT For

• Couples who can't agree on the basic terms of the split — you need a lawyer or mediator to negotiate, not just certify
• Situations involving hidden assets, trust structures, or business interests requiring forensic valuation — the preparation work itself requires professional expertise
• Anyone facing family violence — seek legal advice from the outset through a community law centre or legal aid
• Very short relationships (under three years) — for marriages and civil unions, Sections 14 and 14A create a contribution-based analysis rather than automatic equal sharing; for de facto relationships, the PRA may apply only if (a child is involved or a partner has made substantial contributions) and failing to divide the property would cause serious injustice

Frequently Asked Questions

Is it legal to prepare my own financial brief for a Section 21A agreement?

Absolutely. The PRA requires independent legal advice and certification — it doesn't require that a lawyer does the administrative preparation. You can inventory your assets, classify them, calculate values, and draft a settlement proposal yourself. Your lawyer reviews your work and provides the legal advice and certification.

What if my lawyer says my preparation work is wrong?

That's exactly what you're paying them for. A lawyer who reviews your completed brief and identifies errors in classification or valuation is providing genuine legal value. That's different from a lawyer who spends three hours at $350/hour sorting through unsorted bank statements — which is administrative work you could have done yourself.

How long does the self-preparation take?

Most couples spend 8–15 hours over one to two weeks on the full preparation process: gathering documents, completing the inventory, classifying assets, calculating KiwiSaver splits, and drafting a settlement proposal. It's not fast, but it's work you'd have to do anyway — the question is whether you do it at your own pace or on a lawyer's clock.

Can I use the same preparation for Agreeable instead of a private lawyer?

Yes. Agreeable's online questionnaire requires the same financial information — asset values, property classification, KiwiSaver balances. Walking into the Agreeable process with a completed financial brief makes the questionnaire faster to complete and reduces the risk of missing assets or getting values wrong.

What happens if we can't agree on the split during preparation?

The preparation work is still valuable. Even if you disagree on specific items — who keeps the family home, how to offset KiwiSaver — having a complete, organised inventory means your lawyer or mediator can focus on the disputed points rather than spending time figuring out what you actually own. FDR mediation (Family Dispute Resolution) is a common next step for couples who agree on most things but need help with specific sticking points.
