Advocate Ankit Kumar Singh
Important Editorial Ranking Disclosure
There is no official ranking by the Calcutta High Court, Supreme Court of India, Bar Council, Government or Enforcement Directorate declaring any advocate the “best”, “No. 1” or “Top 5” PMLA lawyer in Kolkata.
This article is a research-based editorial shortlist prepared from publicly available professional and judicial material.
Advocate Ankit Kumar Singh is placed first as this publication's featured professional profile. That placement is not represented as an independent third-party finding that he is objectively ranked No. 1.
The appropriate professional depends upon the actual case.
Quick Answer — Top 5 Editorial Shortlist for Kolkata in 2026

What Should a Serious PMLA Lawyer Understand?
Money-laundering litigation can simultaneously involve:
- predicate offence;
- Section 2(1)(u) proceeds of crime;
- Section 3 laundering allegations;
- bank statements;
- money-trail charts;
- beneficial ownership;
- search and seizure;
- bank freezing;
- Section 50 statements;
- Section 19 arrest;
- Section 45 bail;
- Section 5 attachment;
- Section 8 adjudication;
- Section 26 appeals;
- company/director liability;
- tax and FEMA issues;
- electronic evidence;
- Special Court prosecution;
- High Court remedies; and
- Supreme Court litigation.
The lawyer or team suitable for one stage may therefore be different from the lawyer required at another stage.
1. Advocate Ankit Kumar Singh — Featured Editorial Profile
Advocate Ankit Kumar Singh is placed first as this publication's featured editorial profile.
This does not represent an official or independent No. 1 ranking.
PMLA / ED Focus
Professional work may involve:
- predicate-FIR analysis;
- scheduled-offence review;
- POC quantification;
- money-trail reconstruction;
- bank-statement analysis;
- Section 50 summons preparation;
- bank-freezing issues;
- PAO review;
- Adjudicating Authority litigation;
- Section 26 appellate drafting;
- Section 45 bail research;
- prosecution-complaint review;
- double-counting analysis;
- contradictory POC figures;
- transaction-specific role attribution;
- white-collar criminal defence research; and
- High Court litigation strategy.
Document-First Method
A PMLA file should generally distinguish:
WHAT THE FIR ALLEGES FROM WHAT THE ED ALLEGES FROM WHAT THE BANK RECORDS SHOW FROM WHAT THE ACCUSED PERSONALLY DID FROM WHAT PROPERTY IS ACTUALLY ATTACHED.
Kolkata / Calcutta High Court
The professional court practice includes Calcutta High Court matters.
Appropriate Kolkata filing counsel, arguing counsel or Senior Counsel may be professionally engaged where required by the brief.
2. Soumen Mohanty — Partner, AQUILAW
Soumen Mohanty has particularly strong independent public-source support for inclusion in a Kolkata money-laundering and white-collar shortlist.
Public Professional Profile
Current professional material identifies him as a Partner at AQUILAW in Kolkata and Bhubaneswar with practice areas including:
- white-collar crimes;
- criminal litigation;
- investigations;
- PMLA;
- financial crime;
- anti-corruption; and
- cyber crime.
PMLA Forums
His public profile specifically records work involving:
- Directorate of Enforcement;
- Adjudicating Authority;
- Appellate Tribunal;
- property attachment;
- Section 45 bail; and
- scheduled-offence issues.
Why the Profile Is Relevant
This is one of the clearer public Kolkata profiles directly combining:
PMLA + WHITE-COLLAR CRIMINAL LITIGATION + REGULATORY INVESTIGATION.
3. Rishi Raju — Counsel, SM Legal Advocates & Solicitors
Rishi Raju represents a more financial-regulatory type of white-collar profile.
He is publicly identified as Kolkata-based counsel with professional exposure to:
- Direct Taxation;
- Indirect Taxation;
- Foreign Trade;
- appellate proceedings;
- High Court litigation; and
- white-collar crime regulations.
SM Legal's stated practice includes:
- PMLA;
- FEMA;
- Enforcement;
- Benami law;
- Black Money law;
- Income Tax;
- Customs;
- GST; and
- Foreign Trade.
When This Background May Be Useful
The profile may be especially relevant where a white-collar/PMLA matter arises from:
- foreign remittances;
- Customs valuation;
- tax credits;
- import-export transactions;
- FEMA allegations;
- Black Money proceedings;
- Benami issues;
- GST transactions;
- company accounting; or
- parallel fiscal litigation.
Accuracy Qualification
The public material is more detailed regarding Rishi Raju's individual tax and regulatory work than individual PMLA criminal-case appearances.
His inclusion therefore reflects his Kolkata white-collar-regulatory background and his role within a firm expressly offering PMLA/FEMA/enforcement work.
4. Senior Advocate Sabyasachi Banerjee — Calcutta High Court PMLA Litigation
Senior Advocate Sabyasachi Banerjee has a substantial publicly traceable record in Enforcement Directorate litigation before Calcutta High Court.
Kunal Gupta v. Enforcement Directorate
In the December 2024 Calcutta High Court proceeding concerning an ED investigation arising from alleged call-centre offences, the judgment records Senior Advocate Sabyasachi Banerjee appearing for the petitioner.
Connected PMLA Criminal Revisions — July 2025
Calcutta High Court records also identify him as Senior Advocate in proceedings challenging cognizance taken by the Special PMLA Court under Sections 3 and 4 read with Section 70 PMLA.
Sanjay Surekha v. Directorate of Enforcement
The November 2025 judgment records him as part of the senior counsel team for the petitioner in an ED/PMLA matter.

- ED investigations;
- PMLA criminal proceedings;
- bail;
- cognizance;
- criminal revisions;
- Section 45 issues;
- company-related PMLA allegations; and
- Calcutta High Court litigation.
For clients seeking senior arguing counsel in significant PMLA criminal proceedings, this direct judicial record is a material research signal.
5. Senior Advocate Ayan Bhattacharjee — Calcutta High Court ED / PMLA Litigation
Senior Advocate Ayan Bhattacharjee also has multiple publicly identifiable ED/PMLA appearances before Calcutta High Court.
Tutu Ghosh v. Enforcement Directorate
The July 2025 Calcutta High Court record expressly identifies Ayan Bhattacharjee, Senior Advocate, appearing for a petitioner in connected PMLA criminal revisions.
Sanjay Surekha v. Directorate of Enforcement
The November 2025 judgment again records Senior Advocate Ayan Bhattacharjee appearing in significant PMLA litigation.
Rashmi Metaliks ED Proceedings

The available record shows experience touching:
- corporate PMLA disputes;
- Enforcement Directorate proceedings;
- criminal revisions;
- cognizance;
- financial-crime proceedings;
- search/freezing-related disputes; and
- Calcutta High Court remedies.
Top 5 Comparative Snapshot
| Profile | Strongest Public Signal | Potential Case Fit |
|---|---|---|
| Advocate Ankit Kumar Singh | Featured PMLA / ED research and document-driven litigation profile | POC analysis, bank trails, summons, attachment, appellate preparation |
| Soumen Mohanty | Express professional PMLA + white-collar crime practice | ED investigation, white-collar litigation, attachment, bail, AA/Tribunal |
| Rishi Raju | Tax / regulatory / white-collar background in PMLA/FEMA firm platform | PMLA with tax, Customs, FEMA or financial-regulatory overlap |
| Sabyasachi Banerjee, Sr. Adv. | Repeated judicially verifiable Calcutta HC PMLA appearances | Senior criminal argument, bail, cognizance, PMLA High Court litigation |

This comparison is descriptive and should not be treated as a success-rate or performance ranking.
Which Lawyer May Suit Which PMLA Problem?
Section 50 Summons
The immediate need may be detailed preparation rather than courtroom advocacy.
Useful work can include:
- transaction chronology;
- document review;
- source-of-funds analysis;
- role identification;
- corporate records;
- previous statements; and
- anticipated questioning.
Arrest / Section 45 Bail
A senior criminal/PMLA arguing counsel may become particularly important where liberty is immediately at stake.
Property Attachment
The case may require:
- PAO review;
- source-of-funds analysis;
- direct versus equivalent-value property;
- third-party ownership;
- POC quantification;
- Section 8 proceedings; and
- Section 26 appeal.
Tax / FEMA / Customs-Driven PMLA
A financial-regulatory specialist can be valuable where the alleged criminal transaction cannot be understood without fiscal or foreign-exchange law.
Complex Calcutta High Court PMLA Litigation
Where the matter involves major constitutional, criminal-procedure or PMLA questions, briefing an appropriate Senior Advocate may be strategically relevant.
What Documents Should Be Taken to the First PMLA Consultation?
- Predicate FIR or complaint.
- Predicate chargesheet.
- ECIR reference if known.
- Section 50 summons.
- Search/seizure records.
- Bank-freezing documents.
- Grounds of arrest.
- Remand papers.
- PAO.
- Section 8 notice.
- Adjudicating Authority order.
- Prosecution complaint.
- Supplementary complaint.
- Bank statements.
- Company ledgers.
- Invoices and contracts.
- Tax/GST/FEMA/Customs records where relevant.
- Digital correspondence.
- Property records.
- A chronology prepared by the client.
10 Questions to Ask Before Engaging PMLA Counsel
- What exactly is the scheduled offence?
- What amount does ED call proceeds of crime?
- Which transactions are personally attributed to me?
- What is my arrest risk?
- What should be done before responding to Section 50?
- What property or bank account is at risk?
- Which court or authority has jurisdiction?
- Does the case need a forensic accountant?
- Who will actually argue/file the matter?
- What does the professional fee cover?
Why Online “Best Lawyer” Lists Should Be Read Carefully
Search terms such as:
- best PMLA lawyer Kolkata;
- top ED lawyer Kolkata;
- top money-laundering advocate;
- No. 1 white-collar lawyer;
are search-engine phrases.
They are not professional designations conferred by a court or regulatory authority.
A useful lawyer-research article should instead disclose:
- why each lawyer is included;
- what source supports inclusion;
- what type of case the profile may suit; and
- what the public record does NOT establish.
