USA Life Insurance Proceeds Transfer

[wgfwli]

My son purchased a paid up life insurance policy in the state of Texas while married. The benificiary was his wife. A cousin was designated the secondary benificiary. My son and wife later divorced but the insurance policy was not listed in the divorce settlement. My son passed away and according to Texas law, the proceeds must go to the secondary beificiary - his cousin. The cousin wants to give the entire proceeds - $22,000 to my son's ex-wife. The insurance company has already sent the cousin the check. How should the transfer be handled to avoid any taxes or gift tax (report)?
