Your partner co-signed the guarantee. What does that mean?

A signature can move the risk from the company to the person
When a spouse signs a business guarantee, do not assume the risk sits only with the company. The first task is to have an independent lawyer read the actual guarantee, underlying finance documents and any demand. Ask them to explain who has promised what, the amount claimed, and the contractual basis for that claim.
For a construction owner, the pressure often lands at home as well as at work. The practical issue is not whether to panic. It is whether you know what was actually signed, who can demand payment, and whether the creditor has a paper trail that reaches beyond the business entity.
Find the guarantee and check the exact scope
Start with the document itself. Check the names, the date, the credit provider, the debtor, any stated limit, and whether the wording covers future advances or later changes. Put the underlying loan or supply agreement beside it. Ask the adviser to explain the two documents together rather than relying on the guarantee heading alone.
Do not assume consumer-credit safeguards apply to business borrowing. ASIC explains that the National Credit Code has specific borrower and credit-purpose tests, including personal or household use and residential investment. A company business loan is not automatically covered because a spouse guarantees it. Ask your lawyer which rules actually govern your documents.

Check whether your partner had separate advice before signing
One useful factual question is whether your partner had separate legal advice before signing. Record who arranged the meeting, which documents were available, and what correspondence survives. These are details for their lawyer to assess. Having no advice does not, by itself, establish that a guarantee is invalid or that a creditor cannot pursue it.
If someone refers to consumer-credit guarantee warnings or disclosure forms, ask why that regime applies to this particular loan. Do not treat a missing consumer form as proof of a defence to a business guarantee. Keep the signing records and advice correspondence intact, and let the independent adviser assess their relevance to the actual transaction.
Work out what benefit they actually received
Next, check what your partner actually got from the deal. Was the finance for the business they own, for equipment they use, or for a family asset? That context matters because it helps a lawyer understand why the guarantee was given and what facts may matter if the guarantee is later examined.
Gather the loan application, emails, meeting notes, bank statements and any message that explains why the guarantee was asked for. If the papers show the lender knew this was a family-backed deal, that may be important background. If the file is thin, that is also useful to know before anyone starts making assumptions.
Act separately now and get the right advice
Do not treat this as one joint problem with one joint answer. The business issue, the family pressure and the guarantor’s position may overlap, but they are not identical. Your partner needs separate advice based on their own documents, their own signature and their own exposure.
Today, do three things: find the guarantee, check whether independent advice was given, and identify what benefit your partner received. Then arrange separate advice before the creditor escalates or the discussion turns to personal assets. If you need help coordinating that response, call CRP today about legal intervention.
