Definition - What does In-House Counsel mean?
In-house counsel is a lawyer who works within a company structure to provide legal counsel to the company, and is on the company's payroll. This is opposed to an outside counsel which would be a lawyer who works outside of the company structure, and is not an employee of the company.
Justipedia explains In-House Counsel
Often, companies will hire an attorney full time to be an employee of the business so the company has access to legal counsel all of the time. In many cases, companies see this as more efficient than constantly hiring outside counsel to help them with legal issues. For example, a hedge fund may hire a lawyer to work as an in-house counsel. In this case, the in-house counsel may primarily work with finance and business law to help the business.
