Will Corporation Service Company Boston(CSC) accept all legal documents for the subsidiaries of the Liberty Mutual Group?

The answer to this question is yes and no. Generally, when a process server goes to Corporation Services Company the staff will a take the legal papers from the server without checking. Does that mean Corporation Service Company is accepting Service? No! What happens next is the staff checks to see if the company or organization is a client of Corporation Services Company. If they are the registered agent the documents are forwarded to the client company. Otherwise, the law firm or attorney who is attempting to serve the company will receive a letter from CSC stating that the company is not a client of CSC. Therefore, service is not valid. Bad service of process results in delays. Delays in discovery and court dates. Not to mention unhappy clients.
