About this Document

What Is a Mortgage Discharge Authority?

A Mortgage Discharge Authority is a formal written instruction you send to your bank or lender. You sign this document to tell the lender to release the mortgage they hold over your property title. This usually happens when you have paid off your home loan in full, when you are refinancing to a new lender, or when you have sold the property.

Until this process is complete, the bank keeps a hold on the property title. Even if you have made the final repayment, the land records will still show the bank has an interest in the land. The discharge authority is the trigger that removes this interest. In the Australian property market, this document is essential. It acts as the final step separating you from your debt obligations regarding that specific piece of land.

For business owners and tradespeople, this document is particularly relevant. You might be selling a business premises, paying out the loan on your workshop, or refinancing to free up capital for your next venture. The authority ensures the bank updates the register at the land titles office to reflect that you own the property outright or that a new lender is taking over.

While the term sounds complex, the document itself is usually a standard form provided by your bank. However, the way you fill it out and execute it has strict legal requirements.

When to Use This Document

You will need to use a Mortgage Discharge Authority in several specific scenarios. Understanding these moments helps you prepare for the paperwork and timeframes involved.

Paying Out a Loan in Full

This is the most common scenario. If you have sold another asset, received an inheritance, or simply saved enough to pay the remaining balance of your mortgage, you must notify the bank. The money does not clear the title automatically. You need to sign the authority to give the bank permission to lodge the discharge with the land registry. For tradespeople who might have irregular income flows, this could happen after a big contract job allows for a final lump sum payment.

Refinancing to a New Lender

Refinancing is popular in Australia, especially when interest rates change. When you move your home loan to a new bank, the old bank must be paid out. The new lender usually handles much of the paperwork, but they still need you to sign a discharge authority for the old loan. This document tells the old bank that the new lender is paying them out and that they should remove their mortgage from the title. You generally sign this as part of the refinance application process.

Selling the Property

When you sell a property, the conveyancer or solicitor acting for you will arrange the settlement. Part of this process involves paying out the existing mortgage from the sale proceeds. The seller (you) must sign a discharge authority so the bank knows they can release the title to the buyer. If this is not done, the settlement cannot proceed, and the sale may fall through or delay.

Transferring Title

Sometimes you might transfer a property into a family trust or to a spouse. If there is a mortgage on the property, the bank must agree to this transfer. Often, this requires discharging the old mortgage and registering a new one, or at least formally documenting the change. A discharge authority forms part of this administrative step.

Key Sections and Required Elements

Most banks use their own branded forms, but the content required by law is largely consistent across the Australian banking sector. Whether you are dealing with a major bank or a smaller lender, the form will contain these critical sections.

Security and Mortgage Details

This section identifies exactly which loan and property the authority applies to. It is crucial because many borrowers own multiple properties or have held several loans with the same bank over the years. The form will ask for the Loan Account Number and the Title Reference details.

For Torrens title land, this includes the Volume and Folio number. You can find these details on your original loan documents or a recent rate notice. If you provide incorrect details here, the bank might discharge the wrong mortgage or reject the form entirely. This section ensures the bank releases the correct interest in the correct land.

Execution: Who Must Sign

The execution section is where the legal validity of the document is decided. It is not as simple as just signing your name. The requirements differ depending on whether the borrower is a person or a company.

If you are an individual borrower, all people listed on the mortgage must sign. For example, if you and your spouse bought a property together, both of you must sign the discharge authority, even if you have separated or one person contributed more to the repayments.

If the borrower is a company, such as a family trust or a business structure owning a workshop, the rules are much stricter. You must adhere to the Corporations Act 2001 (Cth). Generally, this means two directors or one director and one company secretary must sign. If a company has a sole director who is also the sole secretary, that person can sign, but they must do so in the presence of a witness who also signs. Failing to follow this structure is a common reason for rejection.

Financial Settlement Instructions

This part of the form tells the bank what to do with any leftover money. If you are selling a property and the sale price is higher than the loan amount, there will be surplus funds. You need to provide your BSB and Account Number so the bank can transfer this money to you. Alternatively, if you have a conveyancer acting for you, you might instruct the bank to pay the surplus into their trust account. If you are refinancing, the instructions usually direct the bank to use the funds to pay out the loan balance to the new lender.

Electronic Lodgment Consent

Australia has moved towards electronic conveyancing through platforms like PEXA (Property Exchange Australia). The discharge authority will contain a clause asking for your consent to deal with the discharge electronically. By signing this, you agree that the bank does not need to send you a paper deed to manually lodge at the land titles office. Instead, they lodge the discharge electronically. This speeds up the process significantly and is now standard practice in most states and territories.

How to Write a Mortgage Discharge Authority (Step by Step)

While most banks provide the actual form, "writing" the authority effectively means filling it out correctly and preparing the supporting information. Here is a practical step-by-step guide for Australian business owners and borrowers.

Step 1: Obtain the Correct Form

Do not try to draft this document yourself on a blank page. Go to your lender's website and search for "Discharge Authority Form" or "Mortgage Release Form." Ensure the form is current. Some banks update their forms to include new privacy clauses or AML/CTF requirements. If you are refinancing, your new solicitor may send you the old bank's form pre-filled with your details.

Step 2: Fill in Loan and Property Details

Enter your loan account number carefully. Cross-reference this with a recent bank statement to avoid typos. Enter the property address exactly as it appears on the title. If you have a strata title or a Torrens title, include the Volume and Folio numbers. This precision prevents administrative delays.

Step 3: Determine the Execution Method

Check the borrower entity on the loan documents. Is it in your personal name, joint names, or a company name?

  • Individuals: All borrowers must sign.
  • Companies: Check the company constitution and the Corporations Act 2001 (Cth). If you are a small business owner with a company structure, ensure you have the appropriate signatories available. Do not have one director sign for both unless they are also the secretary and have a witness.

Step 4: Organise a Witness

In most cases, and certainly for companies executing under Section 127, you need a witness. An eligible witness is usually someone over the age of 18 who is not a party to the loan. A Justice of the Peace (JP) is a standard choice for witnessing these documents in Australia. The witness must see you sign the document. They must then print their name, sign, and provide their address and occupation on the form.

Step 5: Complete Identity Verification

Under the Anti-Money Laundering and Counter-Terrorism Financing Act 2006 (Cth), banks must verify your identity before processing a discharge. Even if you have been a customer for 20 years, they often need to re-verify you when large sums are moving or the mortgage is closing. Attach certified copies of your current Driver's Licence or Passport. Ensure your ID is not expired. If you are doing this in person at a branch, bring the original IDs.

Step 6: Submit Early

Timing is critical. Banks often take time to process these requests. If you are selling a property, your conveyancer will need the discharge authority submitted at least 10 to 15 business days before settlement. If you leave this to the last minute, settlement might be postponed, and you could incur penalty interest. Submit the form via your bank's secure online portal, by mail, or in person. Keep a copy for your records.

Common Mistakes to Avoid

Many discharge processes get delayed because of simple administrative errors. Avoiding these mistakes can save you weeks of frustration.

Incorrect Company Signatories

This is the most frequent error for business owners. If a company owns the property, having just one director sign without the proper authority invalidates the document. The bank's legal team will reject it immediately. You will then have to re-print, re-sign, and re-witness the document. This delay can be disastrous if you have a settlement deadline looming.

Missing Borrower Signatures

Sometimes people forget that a spouse or business partner who went "off title" years ago might still be "on the loan." The mortgage discharge authority requires signatures from everyone on the loan, not just everyone on the title. Check your original loan contract to see exactly who is listed as a mortgagor. If you miss a signature, the bank cannot legally release the mortgage.

Expired Identification

Providing a Driver's Licence that expired last week is a common oversight. AUSTRAC regulations are strict. The bank cannot use the discharge authority to process the transaction if the identification documents are out of date. Check the expiry dates on your ID before you get them certified.

Ignoring Discharge Fees

Most banks charge a fee to process a discharge, typically ranging from $150 to $350 or more. Some banks deduct this from your payout funds. Others require you to pay the fee separately before they process the form. If you do not pay the fee or provide instructions to deduct it, the bank will put the process on hold. Check your loan contract or call the bank to ask about the current discharge fee and how to pay it.

Legal Considerations (AU)

Navigating the legal landscape of mortgage discharge requires an understanding of both federal and state laws. The rules vary depending on where your property is located and how you own it.

Corporations Act 2001 (Cth)

If a company is the borrower, this Act is the primary legislation governing how documents are signed. Section 127 sets out the execution rules. A company must sign the document in accordance with its constitution. The standard safe harbour is two directors or one director and one company secretary. If a company does not follow this, the bank may refuse to accept the discharge authority. This protects the bank from legal claims that the discharge was not authorised by the company.

State Property Law

The actual registration of the discharge happens at a state level. Each state has its own Property Law Act or Transfer of Land Act.

  • New South Wales: The Conveyancing Act 1919 and the Real Property Act 1900 govern these processes. The discharge must be lodged with NSW Land Registry Services.
  • Victoria: The Transfer of Land Act 1958 applies, and dealings are managed through Land Use Victoria.
  • Queensland: The Land Title Act 1994 is the relevant legislation.

While the discharge authority is the instruction to the bank, the bank uses that authority to create a document that complies with these state laws. If you are handling a property transaction yourself, without a conveyancer, you should familiarise yourself with the specific requirements in your state.

Electronic Transactions and PEXA

The National Electronic Conveyancing System (NECS) has largely replaced paper settlements. The Electronic Transactions Act 1999 (Cth) and state equivalents allow for electronic dealings. When you sign the discharge authority, you are often consenting to the bank creating an electronic discharge instrument in PEXA. This means you will not receive the old paper title deed back in the mail. Instead, the title becomes electronic. You can access it through the land registry's online portal if you need it later. If you specifically want a paper title, you may need to request this explicitly, though some states have abolished paper titles entirely.

Banking Code of Practice

The Banking Code of Practice (2020) is a set of obligations that major banks subscribe to. While not law, it carries significant weight. The code requires banks to process discharges within a reasonable timeframe and to keep customers informed. If your bank is delaying the discharge without a valid reason, such as a missing document or a legal complication, you may be able to raise a complaint citing the code. However, to ensure the bank meets its obligations, you must provide a correctly filled-out and signed authority in the first place.

Frequently Asked Questions

Do I need a lawyer to sign a Mortgage Discharge Authority?

You generally do not need a lawyer to sign the authority itself if you are an individual borrower. However, if the document involves a company structure, complex trust arrangements, or you are unsure about the execution requirements, getting legal advice is wise. Many people engage a conveyancer to handle the entire settlement process, which includes submitting this form.

How long does the discharge process take?

Once the bank receives a correctly executed authority, the processing time varies. It usually takes between 10 and 20 business days. If you are refinancing, the new bank often coordinates the timing to ensure the discharge happens on the same day as the new loan settles. If you are selling a property, your conveyancer will factor this timeframe into the settlement date in the contract of sale.

What happens if I lose my original title deed?

If you have an old paper title deed and it has been lost or misplaced, you must inform the bank immediately. They cannot simply discharge a mortgage that relies on a deed they do not have. You may need to sign an indemnity form. This form protects the bank if the lost deed later turns up and causes issues. With the move to electronic titles, this problem is becoming less common, as the title is held virtually by the land registry.

Can I discharge a mortgage early?

Yes, you can discharge a mortgage at any time by paying out the full loan balance. You should check your loan contract for early termination fees or break costs. These fees can be significant if you have a fixed-rate loan. The discharge authority itself does not trigger these fees, but the act of paying out the loan early will. Always ask your bank for a payout figure that includes all fees and charges before you arrange the discharge.

Is the discharge authority different if I use PEXA?

The content is largely the same, but the method is different. In a PEXA workspace, the discharge authority is often an electronic consent you give within the platform. However, most banks still require a wet-ink signed form to be uploaded as a source document for their records before they will authorise the electronic discharge in the workspace. You should treat the digital and paper forms with the same level of care and legal attention.
