Law Firm & Estate Planning Payment Solutions UK

A client pays a legal firm £2,000 by card.

But what exactly is that £2,000?

Is it payment of an issued bill? Money paid on account before work is completed? Money for a disbursement? Or money that belongs to the client or a third party?

For solicitors and legal businesses, what the money represents can be just as important as how the client pays it.

A law firm may want to accept cards, send payment links, collect staged fees, take telephone payments or offer finance. But the payment setup also needs to fit the firm's accounting responsibilities, regulatory position, case-management systems and reconciliation process.

This guide explains how solicitors, legal-services businesses and estate-planning firms can approach payment processing, including merchant accounts, card payments, client money, payment links, instalments, recurring payments, integrations and legal-fee finance.

Payments for Law Firms & Estate Planning Businesses

• Law firms can accept debit and credit card payments, payment links, telephone payments and recurring payments where supported by their payment provider.
• Before choosing how a client pays, legal firms should establish what the payment represents and where the money should settle.
• Payments for an issued legal bill are different from money received in advance, client money and funds held for third parties.
• SRA-regulated firms must consider the SRA Accounts Rules when receiving and handling client money.
• Payment links can be useful for remote clients and can make it easier to attach payments to an invoice, client or matter reference.
• High-value card payments can create chargeback exposure, so firms should consider payment risk as well as client convenience.
• Staged payments, recurring payments, merchant-provided instalments and third-party finance are different payment arrangements and should not be treated as interchangeable.
• Qualifying third-party Deferred Payment Credit, commonly referred to as Buy Now Pay Later, became FCA regulated on 15 July 2026.
• For larger firms, integration with case-management, practice-management and accounting software can be as important as the card-processing rate.
• Payment providers should be compared on sector acceptance, payment flow, settlement, reconciliation, integration, risk and total cost rather than headline pricing alone.

The Legal Payments Problem Is Not Just How a Client Pays

Most payment comparisons start with the payment method:

• card;
• bank transfer;
• payment link;
• telephone payment;
• recurring payment;
• instalments; or
• finance.

For a legal firm, there is another question that should come first:

What is the client paying for, and where should that money be held?

This matters particularly for firms regulated by the Solicitors Regulation Authority (SRA).

The SRA Accounts Rules set requirements for authorised firms receiving or dealing with money belonging to clients or third parties.

The rules distinguish between money belonging to the firm and client money, and require firms to maintain appropriate systems and controls for the nature and volume of transactions they handle.

Client Money vs Payment of the Firm's Fees

This is one of the most important distinctions when designing a payment setup for a law firm.

Payment of an Issued Legal Bill

A client may simply be paying an invoice for legal services already billed by the firm.

For example:

Legal work completed → bill issued → payment link sent → client pays £750

This is different from accepting money that the firm will hold on behalf of a client or third party.

Money Received Before a Bill Has Been Delivered

The position can be different when a firm takes money in advance.

Under the SRA Accounts Rules, money received in respect of the firm's fees and unpaid disbursements before a bill or other notification of costs has been delivered can fall within the definition of client money.

There are circumstances under the SRA Accounts Rules where a firm that does not otherwise operate a client account may hold certain advance payments outside a client account, subject to the relevant conditions and appropriate information being provided to the client.

Firms should therefore avoid assuming that:

“It is payment towards our fees, so it can automatically settle into our normal business account.”

The timing and purpose of the payment matter.

Money Held for the Client or a Third Party

Legal firms may also receive money that does not belong to the firm.

This could include funds connected with:

• property transactions;
• probate and estate administration;
• settlements;
• trusts;
• disbursements;
• money held as stakeholder; or
• other regulated legal services.

The firm's client-money obligations need to be considered separately from the technology used to initiate the payment.

MAS Insight: Follow the Money Before Choosing the Technology

For a legal firm, we would map:

Client → reason for payment → payment method → settlement destination → client or business account → matter record

That tells you considerably more about the required payment setup than simply asking which provider has the cheapest card-processing rate.

Can Solicitors and Law Firms Accept Card Payments?

Yes. Many solicitors, law firms and other legal-services businesses accept debit and credit card payments.

Cards can be useful for:

• fixed-fee legal services;
• initial consultations;
• wills;
• lasting powers of attorney;
• estate-planning services;
• agreed legal fees;
• invoice payments;
• staged fees;
• small disbursements where appropriate; and
• remote client payments.

The firm still needs to understand what the payment represents and make sure the payment and settlement process is consistent with its regulatory and accounting requirements.

Should One Merchant Account Be Used for Every Legal Payment?

Not automatically.

A payment provider may be technically capable of processing a card, but that does not mean every type of legal payment should move through exactly the same payment route.

For example, a firm might receive:

• £300 for a fixed-fee will;
• £1,500 against a family-law invoice;
• £5,000 on account for future legal work; and
• a much larger sum connected with a property transaction.

Those transactions should not automatically be treated as equivalent simply because the client could theoretically pay each amount using a debit card.

Legal firms should establish:

• whether the payment is client money;
• which account should receive it;
• whether the payment provider supports the required settlement arrangement;
• whether separate Merchant IDs or payment flows are appropriate;
• how the transaction will appear in the firm's accounts;
• how it will be allocated to the correct matter; and
• what happens if the payment is subsequently refunded or disputed.

Why Card Chargebacks Matter for Legal Firms

Card payments have an important characteristic that bank transfers do not: a cardholder may potentially dispute a transaction through the card scheme.

A dispute does not mean the customer will automatically receive their money back, but a payment can become subject to the provider's chargeback process.

That matters where a legal firm:

• accepts a high-value card payment;
• has already carried out substantial work;
• has transferred funds onwards;
• has paid a third party;
• has issued a refund through another route; or
• is holding only a small processing balance when a dispute occurs.

This is one reason legal businesses should not choose payment methods purely for client convenience.

The firm also needs to understand the operational consequences of the payment method being used.

Payment Links for Solicitors and Legal Firms

Payment links can be particularly useful for legal services because many clients do not visit the firm's office every time a payment becomes due.

A typical journey might be:

Invoice raised → payment link generated → link sent by email or SMS → client enters card details → payment confirmed → transaction matched to matter

This can be useful for:

• remote consultations;
• fixed-fee work;
• outstanding invoices;
• probate services;
• wills and estate planning;
• family-law fees;
• business legal services; and
• clients who prefer not to give card details over the telephone.

The most useful payment-link systems allow the firm to attach information such as:

• client reference;
• matter number;
• invoice number;
• amount due;
• office or department; and
• payment status.

For legal firms, that reference data can be almost as important as the ability to take the payment itself.

Payment Link or Telephone Card Payment?

Legal firms frequently still take card payments over the telephone.

That normally involves a virtual terminal or MOTO payment:

Client provides card details → member of staff enters details → transaction submitted

A payment link creates a different journey:

Firm sends secure link → client enters their own card details → online payment is submitted

Moving suitable transactions from manual telephone payments to secure online payment links can reduce the amount of card information staff handle directly and can also make payment references easier to automate.

The firm should still consider PCI DSS requirements, authentication, fraud controls and the payment provider's rules for each transaction type.

Can Law Firms Take Staged Payments?

Yes, where the commercial and regulatory structure is appropriate.

Staged payments can work particularly well where legal work has defined milestones.

For example:

£500 at instruction → £750 at agreed milestone → £750 on completion

But there are two separate issues to consider:

1. How should each payment be treated by the firm?
2. How is the customer agreeing to make those payments?

The firm should establish:

• when each payment becomes due;
• whether a bill has been issued;
• whether money received is client money;
• whether the customer actively makes each payment;
• whether the firm will automatically collect future payments;
• what happens if a payment fails;
• what happens if the legal matter ends early; and
• how any refund will be calculated.

Recurring Card Payments Are Different Again

A recurring card payment is not simply another name for instalments.

With a recurring arrangement, the client may authorise the business to initiate future card transactions according to an agreed schedule or charging arrangement.

This could potentially suit legal services involving regular fees, retainers or ongoing work.

However, storing a client's card details does not automatically give the firm permission to charge the card again.

The customer agreement, transaction classification, stored-credential setup and payment-provider configuration all matter.

Our guide to recurring payment processing explains recurring payments and the considerations businesses should understand when storing payment credentials and collecting future payments.

Can Solicitors Charge Clients Extra for Paying by Card?

Legal firms should be careful about adding a separate card fee to consumer transactions.

UK payment-surcharge rules restrict businesses from imposing surcharges on consumers for a range of common payment methods, including consumer debit and credit cards.

This means the firm's payment-processing costs will normally need to be considered as part of its overall pricing rather than simply adding a debit or credit card fee at checkout.

Businesses should check the rules applicable to the particular customer and payment method before introducing any payment surcharge.

Legal Fee Finance: Where Does It Fit?

Finance is one possible payment option, but it should not be confused with the firm's normal merchant account.

A typical third-party finance journey could look like:

Client needs legal service → finance option presented → customer applies to lender → lender assesses application → approved funding used towards legal service

This differs from:

client pays law firm directly using debit or credit card

and from:

law firm allows customer to pay its invoice over several months.

These arrangements can have different regulatory consequences.

What Changed for Buy Now Pay Later in July 2026?

Qualifying third-party Deferred Payment Credit (DPC), often referred to as Buy Now Pay Later, became FCA regulated on 15 July 2026.

The Financial Conduct Authority explains how the new regime applies to qualifying DPC provided by third-party lenders.

Third-party DPC should not be treated as the same thing as a law firm allowing a client to settle an invoice in stages.

Different credit structures can fall under different rules.

Before offering any legal-fee finance arrangement, a firm should establish:

• who the lender is;
• who supplies the legal service;
• whether interest or other charges apply;
• how many repayments are required;
• the repayment period;
• whether the firm is introducing or broking the arrangement;
• whether another regulated credit activity is being carried out; and
• which firm holds the relevant FCA permissions.

Where there is uncertainty, firms should obtain appropriate regulatory advice.

Legal Services Do Not All Have the Same Payment Journey

Different legal practices collect money in very different ways. That is one reason a single generic “law firm payments” setup may not suit every business.

Wills and Estate Planning

Wills, lasting powers of attorney and estate-planning services are often sold on a fixed-fee or packaged basis.

The payment requirement may therefore be relatively straightforward:

instruction → fixed fee agreed → card or payment link → matter opened

Where services are more expensive, staged payments or third-party finance may also be considered.

Probate and Estate Administration

Probate can involve a more complex distinction between:

• the firm's professional fees;
• money connected with the estate;
• disbursements;
• beneficiary funds; and
• other third-party money.

The payment-processing setup needs to reflect those distinctions rather than treating every incoming payment as revenue belonging to the firm.

Family Law and Litigation

Matters may continue for months and total costs may not be known at the beginning.

Firms may therefore use:

• payments on account;
• interim billing;
• staged payments;
• payment links;
• regular payments; or
• third-party finance where appropriate.

The accounting treatment of money received before billing requires particular attention.

Conveyancing

Conveyancing demonstrates why a merchant account should not be treated as a replacement for a legal firm's client-money and banking arrangements.

A solicitor may allow a client to pay legal fees by card, but large sums connected with the purchase or sale of property involve a very different payment purpose and risk profile.

The firm's regulatory obligations, banking arrangements and client-account processes should determine how those funds move.

Debt Recovery and Collections

Legal and debt-recovery businesses can also receive payments from people who are not necessarily the firm's own client.

That changes the payment flow again.

Providers may want to understand:

• who owes the money;
• who the merchant is collecting for;
• whether the merchant owns the debt;
• whether payments are passed to third parties;
• typical transaction values;
• payment channels; and
• the regulatory structure of the business.

Read our guide to merchant accounts for debt collection companies for more detail.

What About Estate Planning Firms That Are Not Solicitors?

Not every estate-planning business is an SRA-regulated law firm.

That distinction should be made clear when choosing a payment provider.

An estate-planning business may provide services such as:

• wills;
• lasting power of attorney support;
• estate-planning packages;
• probate-related services;
• trust-related services; or
• later-life planning.

The firm's regulatory position depends on the activities it carries out and should not be assumed simply from the words “legal” or “estate planning” in its trading description.

Payment providers will normally want an accurate explanation of:

• what services are supplied;
• who supplies them;
• professional or regulatory status;
• how the business contracts with customers;
• average transaction values;
• when payments are collected; and
• whether any regulated financial products are introduced.

Why Matter-Level Payment Reconciliation Matters

A payment processor can tell a firm:

£850 received successfully.

That is useful.

But the finance team may need to know:

£850 → Client 4821 → Matter 4821/03 → Invoice INV-20491 → Family Law → Manchester Office

For larger legal firms, this difference can create substantial administrative work.

A payment system may need to connect payments with:

• client records;
• matter numbers;
• invoices;
• office or client accounts;
• departments;
• branches;
• fee earners;
• case-management systems;
• practice-management software;
• CRM;
• accounting software; and
• reporting systems.

This is where integrated payments become particularly relevant.

A Useful Test for Legal Firms

Do not ask a potential provider only:

“Can you take card payments?”

Ask them to demonstrate:

Client pays → transaction is identified → settlement occurs → payment reaches the correct accounting destination → matter is updated → outstanding balance changes → finance team can reconcile it

That is the actual payment journey.

Can Law Firms Use Third-Party Managed Accounts?

The SRA Accounts Rules also recognise Third Party Managed Accounts (TPMAs).

Under Rule 11, an SRA-regulated firm can enter into an arrangement with a client to use a TPMA for payments relating to regulated services, subject to specified requirements.

The SRA's guidance on Third Party Managed Accounts explains the requirements firms should consider when using this type of arrangement.

A TPMA is therefore a distinct structure and should not be confused with an ordinary merchant account, business bank account or payment gateway.

What Should Law Firms Compare When Choosing a Payment Provider?

The lowest advertised transaction rate should not be the starting point.

For a law firm or estate-planning business, we would examine the following.

1. What Activities Does the Provider Accept?

The provider needs to understand the actual legal or estate-planning services being supplied.

Payment-provider risk appetite can vary even between businesses that appear to operate in the same broad sector.

2. What Kinds of Money Will Be Collected?

Map whether the payment relates to:

• billed fees;
• payments on account;
• disbursements;
• client money;
• third-party funds; or
• other payment flows.

3. Where Will Transactions Settle?

The firm should understand exactly which bank account receives funds and whether the proposed setup supports its accounting and regulatory requirements.

4. How Will Payments Be Referenced?

Look for the ability to record:

• client reference;
• matter reference;
• invoice number;
• department;
• branch;
• payment type; and
• other information required for reconciliation.

5. Which Payment Methods Are Supported?

This may include:

• card payments;
• payment links;
• virtual terminal;
• recurring card payments;
• staged payments;
• online checkout; and
• finance integrations.

6. How Are Chargebacks and Refunds Handled?

Understand:

• how disputes are reported;
• how evidence is submitted;
• where chargebacks are debited from;
• refund controls;
• user permissions; and
• reporting.

7. Can Payments Integrate With Existing Systems?

For larger firms, identify whether the provider can connect with:

• practice-management software;
• case-management systems;
• CRM;
• accounting software;
• bespoke APIs; and
• internal reporting systems.

8. What Does It Actually Cost?

Once suitability has been established, compare:

• debit-card rates;
• credit-card rates;
• commercial-card pricing;
• international cards;
• per-transaction fees;
• gateway charges;
• monthly costs;
• virtual-terminal charges;
• refund fees;
• chargeback fees;
• settlement;
• contract length; and
• termination provisions.

Our UK payment-provider comparison guide explains why provider fit should normally be established before headline pricing is compared.

What Should a Legal Firm Prepare Before Approaching a Payment Provider?

A clearer application can make it easier for the provider to understand the business during merchant account underwriting.

Useful information can include:

• legal company name;
• trading names;
• professional and regulatory status;
• SRA number where applicable;
• services provided;
• website;
• number of offices;
• monthly card turnover;
• average transaction value;
• largest expected card transaction;
• current payment provider;
• recent processing statements;
• refund and chargeback history;
• card-present/card-not-present mix;
• payment-link requirements;
• whether recurring payments are required;
• case or practice-management software;
• required integrations;
• settlement requirements;
• whether client money is involved;
• how client and business money are separated; and
• details of any finance arrangement being offered.

A provider that understands the complete payment flow is in a much better position to assess whether its service is suitable.

Finding a Payment Provider for a Legal or Estate Planning Business

There is no single payment provider that is automatically right for every solicitor, law firm or estate-planning business.

A suitable arrangement depends on what the business does, what type of money it receives, how clients need to pay, transaction values, regulatory requirements and the systems payments need to connect with.

Merchant Advice Service helps businesses compare payment providers based on these wider requirements rather than simply looking for the lowest advertised transaction rate.

Our service is free to merchants.
