AI Compliance Checking for Corporate Law_

Corporate law teams use AI to track Companies House filing deadlines, maintain PSC registers, monitor director disclosure obligations, and verify regulatory compliance across portfolios of client companies, ensuring that the administrative compliance work that underpins corporate practice happens on time and without gaps. For firms managing company secretarial services across dozens of client companies, this transforms compliance from a spreadsheet-dependent manual process into an automated monitoring system that catches every deadline.

The corporate compliance challenge

Corporate law generates ongoing compliance obligations that extend far beyond the transaction itself. Every company has annual filing requirements: confirmation statements to Companies House, annual accounts to Companies House and HMRC, PSC register maintenance, and director appointment and resignation notifications. Changes in share capital, registered office, articles of association, and company name each trigger filing requirements with specific deadlines.

For a firm managing company secretarial services for 50-200 client companies, these obligations create a continuous stream of deadlines. A confirmation statement must be filed within 14 days of the review period ending. Annual accounts must be filed within 9 months of the accounting reference date (for private companies) or 6 months (for public companies). Director changes must be notified within 14 days. Share allotments must be notified within one month.

The consequences of missed filings range from administrative penalties (late filing penalties for accounts start at £150 and escalate to £1,500) to criminal liability (failure to file a confirmation statement is a criminal offence) to striking off (persistent failure to file can lead to the company being struck off the register).

Most firms track these obligations manually: spreadsheets listing client companies, their accounting reference dates, confirmation statement review dates, and other key deadlines. A paralegal or company secretary maintains the spreadsheet and diarises the deadlines. This works until someone is on holiday, leaves the firm, or the spreadsheet develops errors. At that point, deadlines are missed and the firm faces both the immediate compliance failure and a potential negligence claim.

How AI compliance checking works

Company portfolio monitoring

The system maintains a live register of every client company the firm manages. For each company, it holds:

• Company number and registered details
• Accounting reference date
• Confirmation statement review period
• Current directors and their appointment dates
• Current PSC entries
• Share capital structure
• Registered office details
• Articles of association version

This register is initially populated from Companies House data and your case management system, then maintained through ongoing monitoring. When a change is filed at Companies House (by your firm or by the company directly), the register updates automatically.

Deadline tracking and alerts

The system calculates every upcoming deadline for every company in the portfolio:

Annual accounts: filing deadline calculated from the accounting reference date. For private companies, 9 months from the period end. For public companies, 6 months. For newly incorporated companies, 21 months from incorporation. Alerts trigger at 3 months, 1 month, 14 days, and 7 days before the deadline.

Confirmation statements: the review period is 12 months from incorporation or the last confirmation statement. The filing deadline is 14 days after the review period ends. The system tracks the review period end date and the filing deadline separately.

Event-driven filings: when a corporate transaction is completed through the firm (director appointment, share allotment, registered office change), the system calculates the filing deadline from the effective date and tracks it. If the filing is not completed within the deadline window, escalating alerts go to the responsible fee earner and their supervisor.

Regulatory returns: for FCA-regulated clients, the system tracks regulatory return deadlines (annual returns to the FCA, Gabriel submissions, SMCR annual certification deadlines). These are configured per client based on their regulatory permissions.

The portfolio dashboard shows all upcoming deadlines across all client companies, sortable by deadline date, company, or deadline type. Overdue items appear in red. Items due within 7 days appear in amber. The dashboard gives the company secretarial team a single view of their compliance position.

PSC register maintenance

The PSC (persons with significant control) regime requires every company to maintain a register of individuals and entities that meet the control thresholds (more than 25% of shares or voting rights, the right to appoint or remove a majority of directors, or the right to exercise or actually exercising significant influence or control).

The system tracks:

• Current PSC entries for each company
• Share transfers that might change control thresholds
• Director appointments and resignations that might affect control
• Changes in group structures that alter ultimate control

When a change is detected (a share transfer takes a shareholder above or below the 25% threshold, for instance), the system generates the required PSC register update and tracks the 14-day notification to Companies House.

For group structures, the system maps the chain of control from the ultimate parent to each subsidiary, identifying which entities are registrable PSCs and which are covered by the relevant legal entity exemption.

Director disclosure tracking

Directors have ongoing disclosure obligations: interests in transactions and arrangements with the company, interests in shares, and declarations of interest in proposed transactions. The system tracks director appointments across the portfolio, identifies where a director serves on multiple client companies (creating potential conflict situations), and monitors for transactions where a director has a declarable interest.

For senior managers of FCA-regulated firms, the system tracks SMCR obligations: fitness and propriety assessments, annual certification, and conduct rule breach reporting.

Transaction-triggered compliance

When a corporate transaction completes, the system generates the compliance checklist for the post-completion filings:

Share transactions: stock transfer forms, SH01 return of allotment (for new shares), register of members update, PSC register update if control thresholds change, stamp duty payment within 30 days.

Director changes: TM01 (resignation) or AP01 (appointment) within 14 days, register of directors update, register of directors’ residential addresses update, service address confirmation.

Constitutional changes: special resolution filing within 15 days, updated articles filing, change of name notification where applicable.

Each filing is tracked from the trigger event through to confirmation of filing at Companies House. The system verifies the filing has been accepted (Companies House sometimes rejects filings for errors) and alerts if re-filing is needed.

Integration with practice management

The compliance system integrates with LEAP, Clio, Proclaim, Smokeball, and PracticePanther. Corporate transactions completed through the firm automatically trigger the relevant compliance workflows. Company data is shared between the compliance system and the case management system, avoiding duplicate data entry.

For firms that bill company secretarial services as a retainer, the system tracks which compliance activities have been performed in each billing period, supporting accurate invoicing.

Results from deployment

Corporate teams using AI compliance checking typically see:

• Zero missed Companies House filing deadlines (versus 2-5 per year in manual tracking across a portfolio)
• PSC register accuracy improves because changes are detected from transaction data rather than relying on client notification
• Company secretarial team capacity increases 30-40% as manual diary and spreadsheet management is replaced
• Late filing penalties are eliminated
• Portfolio dashboard gives partners visibility over the compliance position for the first time
