retirement plan benefits

When a husband retired from public education 22 years ago his pension was covered by the Ohio State teachers retirement system. He elected to take less than 100 percent of his pension and leave half to his wife as survivors benefits. Since that time the wife has worked the required years and retired under the same pension plan. My question is can he can he stop the plan for survivors benefits and start to get 100 percent of his pension? If they divorce would survivors benefits continue? - Is this your question?
