Generally speaking, spousal support is set at the time of divorce and, if not, there's typically a provision in the judgment that it's waived. Modification of spousal support may be possible after divorce, but it would be very rare for a court to reopen a case, years later, to award support where none had been previously ordered. As we don't have access to your husband's divorce judgment and don't know his case history, if he wants to know what's possible in his case he should ask a lawyer who is familiar with both, perhaps the one who helped him with the divorce.
