Is this sentence correct?
"when he was ill, his children didn't allow their mother to see him because he would have died"

[birdeen's call]

I'm not sure if I understand the sentence. Do you mean that the mother's visit would have caused his death?

In that case you need to say that they didn't allow her to see him because he was dying.
