Is my family business considered marital property should I get married and later die or divorce?

It depends upon how the business is set up. For best safety, have a pre-nup. Both parties should be represented by sepearate counsel and the agreement should be executed well before the wedding to avoid any later claim of coercion.

if you received your ownership before you marry, it is probably your non marital property in the event of a divorce. but there are many ways around that by a good lawyer. did you receive a real salary or a low one so money could remain in the business? that is just one issue. best if you and your parents consult now with a business and estate planning lawyer. then when you wish to marry, a pre marital agreement would be a good idea. that settles in advance a death case, probate, and a divorce. these are difficult to negotiate while professing love and life long faithfulness to a potential spouse. many divorce lawyers draft pre marital agreements.

You need to talk with a lawyer to map out how to handle the business in the event of a divorce. In the event of your death without a will (Good Lord -- why are you even asking this? Why not just get a will?) she'll have a claim to your share of the business. A prenuptial agreement can address this. It'll probably set you back $1,000 - $2,000. Cheap at twice the price for the peace of mind it will give you and your family. Call for a free consultation: 312 - 987 - 9999
