## Frequently Asked Questions
### Can a compliance officer (MLCO) perform the Regulation 21 independent AML audit internally?
Under Regulation 21(1)(c) and LSAG guidance, the audit function must be independent of the day-to-day AML compliance operation. While larger firms can use an internal audit team not involved in AML, smaller firms must engage external independent specialists.
### What is the statutory maximum fine the SRA can impose directly without tribunal referral?
The SRA can directly fine traditional law firms and individuals up to £25,000 for disciplinary misconduct, and up to £250M or 5% of turnover for alternative business structures (ABSs), with higher fines referred to the Solicitors Disciplinary Tribunal (SDT).
