Small job. Asked for proof of insurance. It was like pulling teeth asking for this.  He finally sends me an expired policy. I say hey it looks expired. At this point im assuming hes uninsured. He says no thats the start date. It clearly says expiration date. Sends me a screen shot of a payment going out of his bank account. Cant even tell who its going to. Me being tired of this back and forth, call the agent on his old policy. She says yes hes insured sends me a updated certification. I send it to him and say looks like we are good to go, lets get this started. And he loses it. Says I had no right to go behind his back, that no one has ever even asked him for proof of insurance, let alone contact his agent. Says I shouldn't own property if I need insurance over such small job. 

Now I have no issues if someone doesnt want to carry insurance. But I personally only choose to work with insured workers. And regardless I will verify if they are insured. 

Did I do something wrong here?

Could I have handled this differently ?
