What are the requirements for getting legally married in Illinois?
Illinois does not require a blood test before a marriage license will be issued. You can marry one day after your marriage license is issued, and your license is good for 60 days after it's issued. After that time, you'll have to get a new one before you can marry.
In Illinois, as in most states, you must be of the age of consent, not be too closely related to your intended spouse, not be married to anyone else, and have sufficient "mental capacity," meaning you understand what you are doing when you marry.
Does Illinois have common-law marriage?
No. In Illinois, you must obtain a marriage license and enter into a legal marriage in order to be considered married. Living together and taking the same name don't create a common-law marriage.
Does Illinois have same-sex marriage?
No. Illinois doesn't allow partners of the same sex to marry, nor does it recognize domestic partnerships, civil unions, or reciprocal beneficiaries. For trends in same-sex marriage laws, see the article Same-Sex Marriage: Developments in the Law.
