Accounting Malpractice Lawsuits

investigating accounting negligence & financial fraud cases

Accounting malpractice lawsuits commonly involve instances where an accountant commits an error, omits critical information, or deviates from normal accounting principles which contributes to legal trouble or a financial loss.

Accountants in Ohio have an obligation to uphold basic accounting standards and ethics, and to exercise professional care in preparing tax returns, reports and other crucial financial documents. Clients have the right to expect fair and honest accounting, and to get reasonable and lawful advice regarding Ohio tax laws.

Should your accountant misrepresent your company or financial statements, you may have a malpractice claim. An Ohio Accounting malpractice lawyer can assist in investigating a fraud or negligence claim, and may be able to recover significant losses that result from accounting errors.

Joe Lyon is an experienced Cincinnati fraud attorney and Ohio accounting malpractice lawyer reviewing financial negligence cases for individual plaintiffs and businesses nationwide.

Types of Accounting Negligence

There are two kinds of accounting malpractice: simple negligence and gross negligence.

Management assumes that accountants will conduct careful audits concerning financial statements prepared for individuals and companies who use this information to make financial decisions.

The following are examples of risk factors accounting professionals can reasonably be held legally responsible for by plaintiffs and an Ohio accounting malpractice lawyer:

  • Financial Incentives
  • Financial Pressures
  • Threatened Profitability
  • Pressure to meet expectations of stockholders or management
  • Pressure to meet financial targets

Questions about Commercial Litigation

What types of business lawsuits are viable?

Our attorneys represent plaintiffs in a wide range of business law, including the following practice areas:

What is Accounting Fraud?

Accounting or financial fraud occurs through the omission, deception or misrepresentation of a contract, prospect, investment, project or other business entity. Accounting fraud litigation can result in monetary damages and irreparable damage to the reputation of a company or brand. Victims of fraud should consult an experienced business law professional. Fraud disputes involve various areas of law and may involve:

  • Fraudulent Inducement or Concealment
  • Misrepresentation, Omission, and Non-Disclosure
  • Falsified Financial Records
  • Intellectual Property Issues
  • Tortious Interference
What is Mercantile Law?

Mercantile law is more commonly known as trade law or commercial law—and it describes the body of law that applies to the rights, relations, and conduct of persons and businesses engaged in commerce, merchandising, trade, and sales.

Commercial law focuses on the sale and distribution of goods, whereas business law focuses on the other aspects of business, including mergers and acquisitions, shareholder rights, employment disputes and property issues. Business law is regulated by both Ohio law and federal law. The federal government primarily governs finance, workplace safety and employment issues, though state laws can differ slightly.

What is a Non-Compete Lawsuit?

Non-compete disputes involve contracts in which former employees agree not to compete with an employer for a specified period of time. Most non-compete lawsuits involve former employees soliciting business from the employer’s customers and not disclosing confidential information.

Properly drafted non-compete contracts are critical for enforceability and adequate protection. Even if litigation cannot be avoided, non-compete agreements in place will help make litigation and settlements easier for all parties.

What are Breach Lawsuits?

Two common types of breach lawsuits include: 

  • Breach of contract lawsuits: 

A contract, or any legally binding agreement, presupposes that both parties must fulfill the terms of the contract. If a contract breach occurs, the affected party can seek legal action and compensation for any actual past, current or future losses.

Commercial attorneys negotiate contracts and commercial agreements, and file lawsuits when the following contracts are broken:

    • Commercial B2B Contracts
    • Buy-Sell Agreements
    • Manufacturing Agreements
    • Partnership Agreements
    • Maintenance Agreements
    • Employment Agreements
  • Breach of Fiduciary Duty

Breach of fiduciary duty generally involves allegations that an individual or company breaches a duty to others.  A fiduciary duty requires a level of loyalty and there are both legal and ethical implications. A breach of fiduciary duty commonly includes claims of fraud and breach of contracts.

Breach of Duty claims should be addressed as soon as possible with the help of business litigation attorneys experienced in commercial law.
