In order to have a marriage without formalities (a "common law marriage"), you need to prove three things. First, you must prove that you lived together (the amount of time doesn't matter), then you must prove that you both had an agreement to be married. Finally, you have to show that he held you out as his spouse. If those three things are proven in court, then your marital estate (everything that the two of you acquired during the marriage) would be subject to a just and equitable division.
