There's more than one type of causative verb pattern: 1. Causative verb + object + V3 (no agent) I had my car repaired I got my car repaired 2. Causative verb + agent + V1 (+ object) I let John repair my car. I made John repair my car. I had John repair my car. Your example about the secretary is the second type.

Past, present, and future forms are correct and natural. I will have Joe paint my house. I will have my house painted [by Joe]. I am going to have Joe paint my house. I am going to have my house painted [by Joe]. I am having my house painted. I had my house painted. I was having my house painted when ... I had had my house painted before ...

Hello! Causative verbs are verbs indicating that something was done for someone or something else. The sentence: ''I have my car repaired'' is not correct because the verb is not in the past tense. The sentence should be like this "I had my car repaired'' - the car was repaired by someone else. The verb is in the past tense and the past participle is ending in _ed. In the sentence: ''please, have your secretary give me the information" This is a request made in the future tense and means "please instruct your secretary to give me the information". So in this case "have" is not the causative (remember the causative has to be in the past tense) but it is the verb indicating "instruction". This would be a better way to write the sentence: "I asked you to please get your secretary to give me the information'' - "asked" is the past participle and "get" is the causative verb. I hope that helps! P.S. Let me know if you need any more information!
