While it never just flat out states whether or not he has an heir, I believe it likely that Amaund intended for the Council to take control. Whether this means Titus's heir would be too young or that he didn't have an heir at all is uncertain. But if an heir was just on stand by waiting for Titus to die, it would kind of undermine what Amaund is having the Dragonborn do.
