I am looking for a lawyer that would help me with an life insurance company that did not pay when my husband passed. The company is Garden State

It has been a long time but everyone has told me that you can't fight an insurance company. But something inside me feels that I should still try to fight for what is owed to me and my son. My husband had a policy with Garden State and they sent him an offer in the mail to up his coverage. He signed the form and a new policy was sent. The premiums were always paid on time, but the insurance company said because he died within two years after uping his insurance amount that they were not liable to pay.
