Payment Processing Designed for Law Firms and Legal Professionals
Law firms that accept credit cards for client retainers and legal services need payment processing that handles IOLTA trust account requirements, recurring retainer billing, and the unique chargeback risk that comes with legal service disputes. Corepay provides law firm merchant accounts with the billing flexibility and compliance awareness that legal practices require.
Challenges Law Firms Face
IOLTA Trust Account Compliance
Law firms must separate earned fees from client funds. Many processors do not understand IOLTA trust account requirements and configure accounts incorrectly.
Retainer Billing Complexity
Monthly retainers, hourly billing invoices, and case milestone payments require flexible billing infrastructure that many processors handle poorly.
Client Chargeback Risk
Clients who dispute legal outcomes or feel overcharged sometimes initiate chargebacks on legal fee invoices, creating costly dispute situations.
Online Payment Collection
Law firms that invoice remotely need clean online payment collection that integrates with their practice management systems.

Law firms have unique billing requirements, and finding payment processing that fits those needs is not always straightforward. The legal services industry is valued at over $396 billion and continues to grow. However, law firms can be classified as high-risk by banks and processors, making it important to choose a provider that specializes in this space.

Payment Solutions for Lawyers
Legal practices need multiple payment channels. The most common methods include virtual terminal processing for online and phone payments, mobile processing for in-person transactions, ACH for cost-effective bank transfers, and payment gateways for web-based billing. We also support recurring billing for retainer arrangements and invoicing for flexible client payment options.
Applying for Your Account
You will need:
- Company EIN document
- Personal and business financial statements
- Proof of operating address
- Articles of incorporation
- Principal’s driver’s license
- Business plan (optional, but helpful)
- Business bank account (voided check)
Having clearly stated refund policies, a compliant website, and a low chargeback history will help speed up your approval and may improve your rates.

Processing Fees
Fees vary depending on the type of payment processing, your chargeback ratio, and the type of law firm. Card-not-present transactions statistically result in more chargebacks than card-present transactions, which affects pricing. The MCC for legal services and attorneys is 8111.
Multiple Merchant Accounts
We recommend operating with multiple merchant accounts to mitigate risk. If something happens with one account, you can continue accepting payments through the other. This is especially important for law firms with high billing volumes.
