Professional liability insurance, also known as errors and omissions insurance, can provide important protection for professionals in a variety of fields. Here are a few reasons why someone might consider buying professional liability insurance:

1. Protection against lawsuits: Professionals who provide services or advice to clients can be sued if their work is deemed to have caused harm or financial loss. Professional liability insurance can help protect against the financial impact of such lawsuits, including legal fees and settlement costs.

2. Fulfillment of contractual obligations: Some professional contracts may require that the service provider carry professional liability insurance. Without this coverage, a professional may be unable to fulfill their contractual obligations.

3. Increased credibility: Having professional liability insurance can demonstrate to clients that a professional takes their work seriously and is willing to take responsibility for any mistakes or errors that may occur.

4. Peace of mind: Knowing that professional liability insurance is in place can provide peace of mind and reduce stress for professionals who work in fields where mistakes can have serious consequences.

Overall, professional liability insurance can be an important investment for professionals who want to protect themselves financially and maintain their reputation within their industry.
