Stative verbs describe states, not actions, so we do not normally use them in continuous tenses. Common stative verbs include know, believe, understand, want, need, own and belong.
Have is stative when it means possession or describes a state: ‘I have a car.’ ‘I don’t have time.’
It can be continuous when it describes an activity: ‘I’m having lunch.’ ‘We’re having a party.’
