What happened when you got divorced, if it was put into your name as part of the divorce settlement then all the papers should have made sure that there was no come back from your husband and that he had no further interest in the property. So if it is solely in your name then it is nothing to do with him anymore, it is yours. If you used a lawyer to transfer the house into your name or for the divorce then I suggest you get in touch with him to find out the position.
