Quick answer
Who has to sign a business loan in NZ depends on how the borrower is set up. A company needs its authorised director or directors, a family trust usually needs every trustee, a sole trader signs personally, and anyone giving a guarantee or mortgaging a property they own signs too. Check the full signer list early, because one unavailable person is a common reason a settlement slips.
Key points
- Work out the signers by structure first: company directors, trustees, the sole trader, then any guarantors and any co-owners of the security property.
- A family trust is the structure most likely to stall: lenders typically want all trustees to sign, and the trust deed has to allow the borrowing.
- Anyone who owns the property being offered as security, or who guarantees the loan, is a signer even if they aren't in the business.
- For a mortgage, your lawyer certifies and signs in Landonline, so they need your authority and identity checks done before settlement day, not on it.
Funds are lined up, the settlement date is Friday, and on Wednesday someone mentions that one of the trustees is in Queenstown for a week. This is one of the most avoidable ways to miss a settlement. The money was fine. The signature wasn’t.
This guide lists who signs what, by the way your borrower is set up, and what to line up before the week you need the funds.
Who has to sign a business loan in NZ?
Four groups can be signers. Which ones apply to you depends on the structure and the security:
- The borrower. A sole trader signs personally. A company signs through authorised directors. A family trust signs through its trustees.
- Guarantors. Anyone who guarantees the loan personally, such as a director or a trustee.
- Security providers. Anyone who owns part of a property or asset being offered as security.
- Your lawyer, when a mortgage is involved. Mortgages are registered electronically, and a conveyancing professional certifies and signs for each party.
Most delays come from groups 2 and 3, because people forget they count. If the loan is property-backed, our property-backed hub explains how the security side works.
Who signs when a company borrows?
A company acts through the people it has authorised, so the first question is who that is. The Companies Office register shows your current directors, and your constitution (or the default rules, if you don’t have one) and a board resolution decide who may sign for the company.
In practice:
- One director, one signature. A single-director company usually signs with that director.
- Several directors. Many lenders accept one or two signing directors under a board resolution, but some ask for all of them. Don’t assume. Ask.
- Director guarantees. If a director gives a personal guarantee, they sign again in that capacity. The same ink, a different promise.
- Recent changes. If a director joined or left recently, make sure the Companies Office record matches reality before settlement. A mismatch is the kind of small thing that sends a file back for a day.
A company with two directors who are travelling at different times needs a plan, not a hope.
Who signs when a family trust borrows?
This is the structure most likely to stall a fast settlement, because the trustees together are the borrower and the trust deed sets the rules.
- Every trustee. Lenders typically want all trustees to sign. The Law Society’s guide to family trusts describes trustees as the people who hold and manage the trust’s assets, which is why the lender wants all of them on the paper.
- The deed has to allow it. Lenders have their lawyers read the trust deed to check the trustees have the power to borrow and to give security. A deed written decades ago can be silent or restrictive. Find it now.
- Majority or delegation clauses. Some deeds let a majority decide, or let trustees delegate functions to one of them. A lender will read the wording before relying on it, so don’t assume it solves a missing signature.
- Trustee duties. Trustees have legal duties under the Trusts Act 2019, summarised on the Ministry of Justice trust law reform page. A trustee who is asked to sign a personal guarantee may reasonably want their own advice first. Build that time in.
- A resolution. Expect to provide a trustee resolution, and sometimes a certificate, saying the trustees agreed to the borrowing.
If there’s a corporate trustee, a company acting as the trustee, you then need that company’s authorised director signing too. Two layers of authority, one deadline.
Who signs when a sole trader or partnership borrows?
A sole trader signs for themselves, which makes this the simplest case. It also means the borrower and the guarantor are the same person, and personal assets are exposed. Sole traders tend to be assessed on trading history and bank statements, which our sole trader and low doc situations page covers.
Partnerships need each partner to sign unless the partnership agreement and the lender allow otherwise. If you’re a partner, check whether your agreement says anything about borrowing.
Who else signs: guarantors and property owners
This is the group people forget. Two rules of thumb:
- If their name is on the record of title for the property offered as security, they sign. That includes a spouse or partner who isn’t in the business and a family member who co-owns the property. Pull a current record of title from LINZ or your lawyer so you know exactly whose names are on it.
- If they’ve been asked to guarantee, they sign. A guarantee is a promise to pay if the borrower can’t, so lenders commonly ask guarantors to take independent legal advice first. That means a lawyer appointment, usually a day or two of lead time.
A guarantor who has never read the document will sometimes pull out at the table. That isn’t a signing problem, it’s a conversation you needed to have in the first week.
What happens on settlement day with a mortgage?
If the loan is secured by a first or second mortgage, the mortgage is lodged electronically. LINZ’s guidance says each instrument in a dealing must be certified and signed by a conveyancing professional, and that for a new mortgage the mortgagor and mortgagee are certified separately.
By certifying, the practitioner confirms they have authority to act for you, that you have the capacity to give that authority, and that they hold evidence supporting both. They usually get that authority with a signed authority and instruction form, which can be signed electronically. Even then, the lawyer must have your identity checked and the form in hand before settlement.
So the practical sequence is:
- Confirm the signer list for the borrower, guarantors and property owners.
- Get each person to your lawyer for identity verification and the authority form.
- Complete guarantor legal advice, if required.
- Collect the trust deed and resolution, or the company resolution.
- Then settle.
If you’re tracking a deadline, how quickly a business loan can settle shows where this sits among the other steps.
What should you have in hand this week?
A short list saves a lot of back-and-forth. Gather these before the lender asks:
- The current record of title for any property offered as security.
- The trust deed and any deeds of variation, if a trust is involved.
- A Companies Office extract showing current directors and shareholders.
- Photo ID for every signer, plus proof of address where the lawyer asks for it.
- Each signer’s availability from now until settlement, including travel.
- The name of the lawyer acting for you, and confirmation they’re across the date.
Fifteen minutes on this list is cheaper than a day of delay.
A worked example
Say a Tauranga builder is buying a section off the plan, with a deposit due in ten days. A family trust owns the builder’s house, which will be offered as security for a second mortgage. The trust has two trustees, the builder and their sibling, and the builder will also guarantee personally. The sibling is overseas for another two weeks.
Spotting that on day one gives options: the sibling signs remotely with a lawyer, or a deed clause that allows delegation is checked, or a different security is considered. Spotting it on day nine leaves one option, which is asking the seller for more time. Same loan, same lender, a very different week.
Can a lender help you check the signer list?
Yes, and it’s worth asking early. Our lender checks guide lists the other items a file needs. If your deadline comes from a finance condition rather than a settlement date, what to do in the last week of a finance condition covers that clock.
If you want to know what your own signer list looks like before you start, check your options with the structure, the property and the date, and a real person will tell you who needs to be in the room.
Ready to find out where you stand?
Settlement weeks go better when the awkward questions are asked in week one. Who owns the property, who’s guaranteeing, and where is everyone on the date? Tell us the structure, the security and the deadline, and someone who has seen hundreds of these will look at your individual situation and call you.
Enquiring takes about 60 seconds, and your credit file isn’t touched just for asking. We don’t send your details to a pile of lenders, so your phone won’t light up with strangers. Please fill the form in accurately, including who owns what and who would sign, so we can match the right option first time.
Frequently asked questions
Do all directors have to sign a business loan in NZ?
Not always. A company acts through the people its constitution and a board resolution authorise, and many lenders accept one or two signing directors. If the lender asks for every director, or if a director is giving a personal guarantee, that person signs as well. Check who is authorised before settlement week.
Do all trustees have to sign when a family trust borrows?
Lenders typically want every trustee to sign, because the trustees together are the borrower. Some trust deeds allow majority decisions or delegation of a trustee's functions, and a lender will read the deed to see what applies. If one trustee is overseas or unwell, say so on day one.
Do I need to give a personal guarantee on a business loan?
Often, yes, especially for a company or trust with a short history. A personal guarantee means the guarantor can be pursued personally if the borrower can't pay. Whether one is needed, and for how much, depends on the lender and the deal, so ask early rather than finding out at signing.
What is independent legal advice for a guarantor?
It's when a guarantor talks to their own lawyer before signing and the lawyer certifies they understood what they were signing. Lenders commonly ask for it, particularly where the guarantor isn't a director or owner. It adds a lawyer appointment to the timetable, so book it as soon as you know a guarantee is needed.
Can loan documents be signed electronically in NZ?
Many loan documents can be, and a mortgage is registered electronically through Landonline by a lawyer or other conveyancing professional who certifies and signs for each party. Even so, the lawyer must hold your authority and have checked your identity first, so the preparation still has to happen before settlement day.
What if the person who has to sign is overseas?
Tell the lender and your lawyer straight away. Remote signing, a properly drafted power of attorney, or a trustee delegation may solve it, but each needs time and a lawyer's sign-off. Leaving it until the week of settlement is how a few days become a missed date.
Does my partner have to sign if they're not in the business?
Only if they own part of the property being offered as security, or they are giving a guarantee. Ownership is shown on the record of title, so check whose names are on it. If your partner's name is there, they're a signer.
