Our Core White-Collar Practices in New York City

Lowther | Walker provides aggressive pre-indictment and trial defense across the entire spectrum of federal financial and corporate crimes prosecuted in NYC:

Securities Fraud, Insider Trading & SEC Enforcement (SDNY Focus)

The SDNY is widely considered the capital markets prosecutor for the United States. We defend hedge fund managers, institutional brokers, corporate officers, and crypto platform founders facing parallel criminal DOJ charges and civil SEC enforcement actions:

  • Insider Trading (15 U.S.C. § 78j(b)): Challenging government allegations regarding material non-public information (MNPI) and tipping networks.
  • Market Manipulation & Accounting Fraud: Defending against alleged revenue inflation, mark-to-market valuation errors, and falsified public disclosures.
  • SEC Wells Notices & Rule 102(e) Defense: Intervening during SEC investigations to prevent administrative bans for accountants, auditors, and officers.

Federal Wire Fraud & Mail Fraud (18 U.S.C. §§ 1341 & 1343)

Federal prosecutors in New York routinely utilize broad wire fraud statutes as a catch-all for complex commercial disputes, real estate escrow transactions, and corporate financing arrangements. We dismantle wire fraud allegations by proving the lack of intent to defraud and demonstrating that disputed transactions were legitimate business practices.

Bank Fraud, Mortgages & Real Estate Escrow Schemes

New York’s high-stakes real estate market faces scrutiny from federal regulators. We represent developers, lenders, and mortgage brokers accused of inflating financial statements, loan application fraud, or bank fraud under 18 U.S.C. § 1344.

International Money Laundering & FCPA

With NYC serving as a global banking hub, federal agencies aggressively prosecute international capital transfers under the Bank Secrecy Act (BSA) and the Foreign Corrupt Practices Act (FCPA). We defend corporations and foreign nationals against trade-based money laundering, shell company allegations, and OFAC sanctions violations.

Federal Tax Evasion & IRS Criminal Investigation (IRS-CI)

We represent high-net-worth individuals, corporate CFOs, and tax preparers targeted by the IRS-CI New York Field Office for offshore account non-disclosure (FBAR), tax shelter utilization, and corporate tax evasion.

Answers to Your White-Collar Case Questions

What happens when FBI agents contact a New York City executive before filing federal fraud charges?

The executive should take the contact seriously and avoid making substantive statements before speaking with defense counsel. Investigators may be seeking information, assessing cooperation, or gathering evidence against the executive or others involved in the business.

Potentially. Federal prosecutors may examine whether electronic communications were used as part of an alleged scheme to obtain money or property through materially false or fraudulent representations. The specific communications, intent, investor reliance, and surrounding business context can all become important.

The subpoena should be reviewed immediately by counsel experienced with securities enforcement and criminal investigations. SEC matters can involve referrals or parallel investigations by federal prosecutors, making early coordination especially important.

Yes. The same underlying billing practices or alleged misconduct can potentially lead to criminal, civil, and administrative consequences. A coordinated defense strategy may be necessary when multiple government agencies are involved.

It can create serious legal problems. Once a person or company has a duty to preserve relevant evidence, deleting records may expose individuals to allegations involving obstruction or destruction of evidence.

Federal jurisdiction and venue depend on the specific facts of the alleged offense. Communications, financial transactions, participants, victims, and other conduct occurring in different districts can all affect where a federal case may be investigated or prosecuted.

The answer depends on the person’s employer, licensing status, regulatory obligations, and the nature of the investigation. FINRA, the SEC, employers, and other regulatory bodies may impose separate requirements or restrictions.

Yes, pre-indictment advocacy can sometimes be an important stage of a federal white-collar matter. Counsel may present facts, legal arguments, mitigating information, or other materials to prosecutors while seeking to influence charging decisions.

Possibly, but approval alone does not automatically establish criminal conspiracy. Prosecutors generally must attempt to establish an agreement to participate in unlawful conduct, along with the required knowledge and intent.

Investigators may examine the source of funds, ownership structures, bank transfers, intermediaries, and communications surrounding the transaction. Depending on the allegations, the government may investigate potential money laundering and seek asset forfeiture.

High-value Manhattan and Brooklyn real estate transactions are prime targets for wire fraud investigations. This occurs in two ways: (1) Business Email Compromise (BEC), where hackers spoof realtor or attorney emails to divert escrow wire transfers; and (2) Material Misrepresentations, where developers, buyers, or brokers lie about appraisals, occupancy rates, or loan documents transmitted via email to secure financing.
