I bought insurance for pigs, but the pigs died two days before the insurance came into effect. In this case, the insurance will not pay the claim, because the insurance has not yet taken effect. Only after the insurance comes into effect will the insured or animal get sick or die, and there will be a period of observation after just buying insurance. If something happens during that time, the insurance won't pay for it. So even if you buy insurance for pigs, if the pigs die two days before the insurance takes effect, the insurance will not pay. Insurance generally has a waiting period. When you insure a live pig, you may already think that the live pig is going to die soon. Before you insure the pig, you can claim directly after the pig dies, which is a very sure business for you. In order to prevent this from happening, insurance companies have increased the waiting period in each insurance. If the insurance mechanism is triggered during the waiting period, the insurance will not make claims. Therefore, although your pigs have bought insurance, the insurance is still in the waiting period and has not officially taken effect. During this period, if the pig dies, the insurance company does not need to pay for your claim according to the corresponding terms. It's also a pity that the pig you insured died when it was about to take effect in two days, but there's nothing you can do because it hasn't taken effect yet. I blame you for not insuring this pig earlier.
So if you buy insurance, but the insurance is still in the waiting period and it doesn't take effect, and the person or thing you insured triggers the insurance mechanism, then the insurance company doesn't need to pay for you. In doing so, insurance companies are also worried that some people will know that they are about to trigger the insurance mechanism before they want to buy insurance and then get the premium. Moreover, the waiting period of general insurance is not very long, at most, it is 90 days. Under normal circumstances, the insurance bought will not happen so soon. If something really happens during the insurance period, there is no way out, because insurance will not compensate.
