Do you need a solicitor to remortgage?

The short answer is yes, you’ll normally need legal work when you move your mortgage to another lender. In England and Wales, a solicitor or licensed conveyancer can handle it; in Scotland and Northern Ireland, you’ll usually use a solicitor who handles conveyancing in that jurisdiction. They handle the legal work needed to repay the existing mortgage and register the new lender’s security. But you may not need to find or pay a firm yourself, because some lenders arrange a basic legal service.

A straightforward rate switch with your existing lender is different. Known as a product transfer, it generally doesn’t involve conveyancing unless other changes require legal work.

This guide covers remortgaging across the UK, including the different legal systems in England and Wales, Scotland and Northern Ireland. Check that the firm handling your legal work can act where your property is located and meets your lender’s requirements.

When do you need legal work for a mortgage change?

The answer depends on what you’re changing. A remortgage to another lender replaces your existing mortgage without moving home. A product transfer changes your deal with the current lender.

Lloyds’ public conveyancing guidance distinguishes a new-lender remortgage, which requires conveyancing, from a product transfer, which doesn’t.

Proposed change	What to check about legal work
Moving to another lender	Conveyancing is normally needed to replace the lender’s security.
Switching rate with the same lender	A straightforward product transfer generally doesn’t require conveyancing.
Adding or removing an owner	Separate legal work may be needed, even if the lender stays the same.
Borrowing more from the existing lender	Check the lender’s requirements and whether ownership or security arrangements are changing.

Staying with the same lender doesn’t settle the question on its own. Changing ownership alongside a rate switch is different from choosing another mortgage product without other changes.

One of the first things we would want to understand is whether you’re changing only the mortgage deal or also changing who owns the property. That helps identify which legal requirements need checking before you commit to a route.

What does a solicitor or conveyancer do when you remortgage?

Conveyancing is the legal work involved in the transaction. In England and Wales, a solicitor who handles property work or a licensed conveyancer can undertake it, subject to the lender’s requirements. For Scotland and Northern Ireland, check that your solicitor handles remortgages under the relevant legal system.

Even though you aren’t selling your home, the mortgage secured against it is changing. The legal work deals with the existing lender’s security and the registration of the new lender’s security. The terminology and documents vary: in Scotland, the security granted to a mortgage lender is called a standard security.

The work normally includes:

• Identity and title checks: confirming who is involved and checking the property’s registered ownership and relevant restrictions.
• A redemption figure: obtaining the amount needed to pay off the existing mortgage for the intended completion date.
• Mortgage conditions and enquiries: addressing relevant requirements concerning the property and proposed loan.
• The mortgage deed or security document: arranging the document needed for the new mortgage under the relevant legal system.
• Completion funds: handling the money used to repay the existing lender and any balance due to you.
• Registration work: arranging the appropriate changes to the registered mortgage security.

Redemption means paying off your existing mortgage. The redemption figure may include interest and charges as well as the outstanding loan balance.

The checks aren’t necessarily identical to those undertaken when you bought the property. Searches and other enquiries depend on the lender and transaction. Registration work can continue after completion, so the new mortgage doesn’t necessarily wait for every registration step to finish before it starts.

In England and Wales, you may be able to sign the mortgage deed digitally using HM Land Registry’s online signing service, where your lender and conveyancer use it. Signing online doesn’t remove the legal work. Don’t assume this particular service or its signing process applies elsewhere in the UK.

Does remortgage conveyancing differ across the UK?

The main distinction between changing lender and making a straightforward product transfer is useful across the UK. The legal professional, security documents and registration arrangements must suit the country where your property is located.

England and Wales

You can use a solicitor or licensed conveyancer accepted by your lender. The licensed-conveyancer framework described here applies to England and Wales. Mortgage registration work is dealt with through HM Land Registry, which doesn’t cover Scotland or Northern Ireland.

Scotland

You’ll usually use a solicitor who handles Scottish conveyancing. Registers of Scotland explains that most conveyancing in Scotland is carried out by solicitors, who check the title and documents supporting the lender’s security.

For a typical switch to a new lender, the legal work includes dealing with the existing standard security and registering the new one. Registers of Scotland calls the deed removing the old security a discharge of a standard security. Paying off the loan alone doesn’t remove that security from the register.

Northern Ireland

You’ll usually use a solicitor who handles Northern Irish conveyancing and meets your lender’s requirements. Registration is handled through Land & Property Services rather than HM Land Registry. Its Land Registry and Registry of Deeds cover different registration arrangements, so the title determines which work is needed.

Whichever part of the UK your property is in, confirm that any free legals package covers that location and ask which legal costs or additional services you’ll have to pay for.

Can the lender arrange the conveyancer?

Some remortgage products include a lender-funded legal package. If you use one, the lender or its service provider will normally arrange the firm undertaking the standard work.

Other options may include appointing your own firm or selecting a product offering cashback towards legal costs, where available. The lender’s acceptance requirements and the product terms still matter.

A lender panel is a group of firms accepted to undertake legal work on that lender’s behalf. Being qualified to handle conveyancing doesn’t automatically mean a firm is accepted by every lender.

You should also establish who the appointed firm represents. Arranging the lender’s security and giving you independent legal advice aren’t the same service.

For example, Nationwide’s published mortgage offer terms, checked on 23 October 2026, state that the conveyancer under its free standard legal service works on Nationwide’s behalf and can’t give the borrower legal advice on the mortgage. Separately arranged advice is payable by the borrower.

Other arrangements can differ. Ask what the firm’s instructions cover rather than assuming every lender-funded service provides the same advice.

What do free remortgage legal packages cover?

“Free legals” generally means a defined package of standard work is paid for. It doesn’t necessarily mean every legal service or third-party charge connected with your transaction is included.

Ask whether additional charges apply for:

• Adding or removing an owner.
• Leasehold-related work or charges from a landlord or managing agent.
• Correcting title problems or discrepancies in names and addresses.
• Shared ownership or shared-equity arrangements.
• Dealing with another loan secured against the property.
• Transferring money or obtaining additional documents.

These are questions to check, rather than universal exclusions. Halifax’s remortgage package, for example, separates basic legal work from potentially chargeable extras such as ownership changes, lease extensions and shared-equity work.

Before accepting a package, ask the provider to confirm what’s included, which extras may apply and whether it can handle the proposed transaction. We wouldn’t assume that an ownership change is covered simply because the mortgage advertises free legal work.

If you’re comparing free legals with cashback, obtain the legal quote first. Cashback may cover only part of the bill, and its payment date may not match when your charges are due. The mortgage’s rate, product fee and other costs also affect the comparison.

Can you use your own solicitor to remortgage?

You may be able to, provided the arrangements meet your new lender’s requirements. Confirm this before instructing the firm or paying charges.

Lloyds’ mortgage features illustrate why this matters: its switcher service uses an appointed conveyancer, while borrowers choosing their own must use an approved-panel firm and pay for that service themselves.

Regional conditions can matter too. The same Lloyds guidance says that, in Northern Ireland, its appointed conveyancer can’t provide you with legal advice or additional services; you must instruct a different conveyancer for those. That is a condition of this lender’s service, rather than a rule for every free legals package.

Your chosen lender may have different arrangements. If your firm can’t act for it or doesn’t handle conveyancing in the country where the property is located, separate representation or a different firm may be needed, potentially adding legal costs.

Ask for an itemised quote covering:

• The professional fee and VAT.
• Disbursements, meaning third-party expenses paid on your behalf.
• Extra work specific to your property or ownership changes.
• What is payable if the transaction doesn’t complete.
• Who will handle the file and how you’ll receive updates.
• Whether the service includes acting for both you and the lender.

A familiar firm may be convenient, but it isn’t automatically the cheapest or fastest option. Equally, a low headline quote is only useful once you understand the work and costs it includes.

When might the legal work be more involved?

Leasehold matters, title restrictions, another secured loan or a change of ownership can make the work different from a routine lender switch. Disclose these early so the provider can confirm the service required.

Hypothetical example: a straightforward lender switch

Two homeowners are replacing their mortgage with a loan from another lender. Ownership stays the same, and there are no known title issues or other secured loans.

A basic legal package may suit the transaction, subject to its terms and the checks revealing no additional requirements. The owners still need to provide documents and complete the requested signing process.

Hypothetical example: removing an owner

A homeowner wants to remove a former partner while moving the mortgage to another lender. This involves more than replacing the mortgage product.

Changing who owes the mortgage and changing who legally owns the property are connected but distinct matters. The lender must approve the proposed borrowing arrangements, while the legal professional handles the required ownership work.

NatWest’s guidance on changing mortgage names gives a lender-specific example of a change requiring the borrower to instruct a solicitor. Don’t assume the standard legal package covers this work or that changing the mortgage alone removes someone’s ownership.

Shared-equity arrangements need attention too. For an existing Help to Buy equity loan in England, there are additional requirements when keeping a Help to Buy equity loan while changing lender. The legal work also differs when remortgaging to repay a Help to Buy equity loan.

What should you check before the legal work starts?

To give your broker and legal provider a clear starting point:

• Explain whether the lender, borrowing amount or owners will change.
• Mention leasehold, shared-equity and other secured-loan arrangements.
• Confirm the legal package or obtain an itemised quote.
• Establish who the firm represents and what advice is included.
• Share the intended completion date and current deal-end date.
• Return requested documents promptly and raise questions about anything unclear.

Outstanding legal enquiries can affect how long a remortgage takes. A target date helps everyone plan, but it isn’t a guarantee that all requirements will be satisfied by then.

When we assess your remortgage options, we’d consider the legal incentive alongside the mortgage’s rate, fees and the changes you want to make. Your legal professional can explain the transaction’s legal implications and confirm their charges.
