Quick answer
A mortgagor is the person or entity that owns a property and grants a mortgage over it to a lender as security for a debt. The lender receiving the security is the mortgagee. In business lending the mortgagor is often not the borrower: a company may borrow while a director, or a director's spouse, puts up the family home, signing as a third-party mortgagor.
Key points
- The mortgagor owns the property and gives the security; the mortgagee is the lender
- Every registered owner on the title has to sign as a mortgagor, not just the one in the business
- A third-party mortgagor risks their property for someone else's debt, often without being a borrower
- The mortgagor's obligations end when the debt is repaid and the mortgage is discharged
The mortgagor is the owner who hands over security. If you own a property and sign a mortgage so a lender will advance money, you are the mortgagor; the lender is the mortgagee. The naming trips people up because it sounds like the person who receives something, but in law the “-or” grants and the “-ee” receives.
Why the borrower and the mortgagor are often different people
In a home loan the two roles usually sit with the same person. Business lending is messier, because the entity that trades and borrows is often a company or a trust, while the property that makes the loan possible is owned by a human being.
Picture a typical structure:
| Role | Who usually fills it |
|---|---|
| Borrower | The trading company (Pty Ltd) or corporate trustee |
| Mortgagor | The director, or the director and spouse, who own the home |
| Guarantor | The same director, signing a personal guarantee |
| Mortgagee | The bank, non-bank or private lender |
A person who mortgages their property to secure someone else’s debt is often called a third-party mortgagor. That label matters, because the security is just as real as if they’d borrowed the money themselves. The RBA’s October 2025 small business bulletin notes that roughly half of smaller SME loans are secured by residential property, so this arrangement is far from unusual.
What signing as a mortgagor commits you to
The mortgage document gives the lender rights over the land until the debt is cleared. Among the usual promises, you keep the property insured, pay the rates, keep it in repair, and don’t sell it or add more security over it without the mortgagee’s consent. In NSW, the land registry’s guidance also describes how a mortgagee can appoint a receiver after a mortgagor defaults.
Two practical points catch owners out:
- Every registered owner must sign. If your home is held jointly with a partner who has nothing to do with the business, they become a mortgagor too. Most lenders will want that person to receive independent legal advice before signing.
- Identity checks are strict. Lenders must verify each mortgagor’s identity before lodging the mortgage, so expect certified ID and sometimes a face-to-face check for every owner, not only the director applying.
If you need funds before the paperwork for a registered mortgage can be finished, a lender may use a caveat instead, but the owner is still giving security over their land.

A worked example
Lena runs a joinery business through a company. It needs $180k to buy a CNC machine and cover a slow quarter. Her bank wants more security than the business has, so a second-tier lender offers a second mortgage over the home Lena owns with her husband, Tom.
The company is the borrower. Lena signs as director, as guarantor and as a mortgagor. Tom, who works as a nurse, also signs as a mortgagor because his name is on the title. He sees a solicitor first, who explains that if the company can’t pay, the lender can look to the house. Two years later the loan is refinanced, the lender signs a discharge of mortgage, and both of them are released.

Thinking about using your property for the business?
Plenty of owners only become mortgagors when the bank declines an unsecured request. If that’s where you are, a home equity business loan or second mortgage may get you there, and it’s worth weighing the options with someone who explains the security plainly first.

One of our team reads it and rings you to talk it through. Give accurate figures for the property and the debt on it, and the first suggestion we make is far more likely to be the right one.
Frequently asked questions
Is the mortgagor the borrower or the lender?
The mortgagor is the side giving the security, which is usually the borrower or someone backing the borrower. The lender is the mortgagee. The '-or' ending marks the person granting the interest, and the '-ee' ending marks the person receiving it.
Can someone be a mortgagor without being a borrower?
Yes, and it's common in business lending. If your company borrows and your home secures the loan, you sign as mortgagor in your own name even though the company is the borrower. You'll usually sign a guarantee as well.
My spouse co-owns our home but isn't in the business. Do they have to sign?
Yes. A mortgage over the whole property needs every registered owner to sign as mortgagor. Lenders will generally ask a non-borrowing co-owner to get independent legal advice first, and the solicitor signs a certificate confirming it.
What happens to the mortgagor if the borrower defaults?
The lender can enforce its rights under the mortgage against the property, which can ultimately mean a sale, even if the mortgagor never borrowed a cent. That's why third-party mortgagors should understand the loan before signing.
How does a mortgagor get released?
Once the secured debt is paid in full, the lender signs a discharge of mortgage and it's lodged with the land registry in that state. The title then shows the property free of that mortgage.
