Would I be able to receive alimony if I have been permanently disabled before I got married???

If you were disabled before you were married then that was part of your condition at the time of your marriage. So presuming that your husband supported you and you were on disability that would be part of your marital status and would not serve in any way to prevent you from applying for alimony. Disability would only be a shield if he were applying for alimony from you.
