Quick answer
When a couple runs a business together, lenders usually want both partners involved. In a partnership, both are typically borrowers and each is liable for the whole debt. In a family company, both directors are usually asked for personal guarantees. If the family home is offered as security, every owner on the title must sign. Clear roles, separate accounts and honest conversations make these loans smoother.
Key points
- In a general partnership, each partner has unlimited liability for the partnership's debts.
- Family companies usually need guarantees from every director.
- If the home is security, both owners sign — even a partner who isn't in the business.
- Agree on the loan's purpose, size and exit plan together before you enquire.

Couples run a huge share of Australia’s small businesses — the café where one makes the coffee and the other does the books, the building company where one runs the jobs and the other chases invoices, the farm, the practice, the shop. When a business like that borrows, it’s rarely a decision one person makes alone, and lenders know it.
This page explains how lenders usually handle couple-run businesses, and the conversations worth having before you sign anything.
How does the business structure change who signs?
The structure decides who is legally responsible, and so who the lender needs.
| Structure | Who usually borrows | Who is liable |
|---|---|---|
| Partnership (both partners) | Both partners together | Each partner, for the whole partnership debt |
| Sole trader (one partner) with the other helping | The sole trader | The sole trader, plus anyone who guarantees or offers security |
| Family company (both directors) | The company | The company, plus each director who signs a guarantee |
| Family trust with corporate trustee | The trustee company | The trustee, plus guarantors |
business.gov.au notes that in a general partnership “each partner has unlimited liability for any debts and obligations the partnership incurs”. That’s worth sitting with: it means either of you could be asked to repay all of it, not just “your half”.
Why do lenders want both partners involved?
Three reasons come up again and again:
- Both of you control the business. Lenders want everyone with authority over the money to be accountable for it.
- Property is often jointly owned. If the family home secures the loan, both names on the title must sign the mortgage.
- It avoids later disputes. A partner who didn’t sign can argue they never agreed. Lenders prefer everyone at the table at the start.
For couples where one partner isn’t involved in the business at all but co-owns the home, our page on borrowing against a home in joint names covers what that partner is agreeing to.
What should a couple agree on before borrowing?
Before either of you fills in an enquiry, sit down together and agree on:
- The purpose. Exactly what the money will do for the business.
- The size. The amount you actually need, not the most you could get.
- The security. Whether the home is on the table, or whether you’d rather explore options that leave the house out.
- The exit. How the loan will be repaid — from trading, a sale, a refinance — and what you’ll do if things go slower than planned.
- The “what ifs”. Illness, a new baby, one of you stepping back. Our guide on money rules for couples in business goes through these gently.
Once you’re on the same page, one short enquiry is all it takes to start. One of you can fill it in.
How do lenders look at a couple’s finances?
They look at the business first — statements, BAS, customers — and then at both of you personally. That can include each partner’s credit file (only once you choose to proceed), other debts such as a home loan, and household spending if a large loan relies partly on personal income.
A common snag for couples is the blur between household and business money. A family company paying the grocery bill, or business income parked in a joint personal account, makes the true business picture harder to see. business.gov.au says partnerships and companies “must have a separate bank account for tax purposes”. Keeping it genuinely separate is one of the best things you can do before borrowing.
Illustrative example: A couple run a small bakery through a family company, both as directors. They want $180,000 to buy the bakery’s freehold shopfront. The lender assesses the company’s trading, asks both directors for guarantees, and takes a first mortgage over the shop plus a second mortgage over their home for the shortfall. Both sign after talking it through with their own lawyer.
What if one partner has credit problems?
It happens more often than people admit. One partner may have a past default, a bankruptcy from years ago, or a debt from before the relationship. It doesn’t automatically rule the business out. Past credit issues are considered case by case, and property security can carry weight where a credit file is patchy. What matters is being upfront early, so the specialist matches you to a lender that’s comfortable with the history rather than one that will decline at the last step.
What happens if the relationship changes?
A loan doesn’t end because a relationship does. Both borrowers and every guarantor stay liable until the debt is repaid or the lender agrees to release someone — often through a refinance. If one of you plans to step away from the business, read releasing a personal guarantee and get advice before anything is signed.
Should each partner get independent advice?
When one partner is guaranteeing a loan or offering a share of the home, many lenders ask that person to get independent legal advice before signing — and even where it isn’t required, it’s wise. It gives the partner who is less involved in the day-to-day business a private space to ask questions and understand the risk. It also protects the relationship: nobody can later feel they signed something they didn’t understand.
Start the conversation together
You make decisions as a team; your lender should talk to you like one. The enquiry takes around 60 seconds, doesn’t involve a credit check, and goes to a single specialist rather than a crowd of lenders. They’ll call to understand the business and who does what. Please be accurate on the form — especially about structure, property ownership and both credit histories — so we can find the right match first time.
Frequently asked questions
Can just one of us sign for the business loan?
Sometimes, depending on the structure. If only one partner is a director or the sole trader, the loan may be in that person's name. But if the other partner co-owns property being offered as security, or is a partner or director, they'll need to sign too.
What happens to the loan if we separate?
The loan doesn't change because your relationship does. Each borrower or guarantor remains liable until the loan is repaid or the lender agrees to release someone. Getting legal and financial advice early is important.
Is it better to be a partnership or a company as a couple?
That's a question for your accountant and possibly a lawyer. For borrowing, both work; the difference is mainly who is liable and how.
Can our business borrow if only one of us has good credit?
Often yes. Lenders look at the whole picture. Tell us honestly about both credit histories and we can match you to lenders that consider past issues case by case.
Do both of us need to be on the enquiry form?
One of you can start the enquiry. Just mention that the business is run by both of you, and the specialist will talk through who needs to be involved.
