If there is one thing to note about divorce is that there is a difference between LGBT and traditional divorce, and that is how the court sees and treats the assets. The court usually places a division between the marital assets and those that are not. When the assets are considered as marital or conjugal, regardless of when the assets got acquired, then they are considered as equally owned by the spouses.
Not only that, a court judge might even consider the positive assets, which include a house, car, or retirement account and even the negative ones, such as a student loan debt. More often than note, the family courts will not take in assets acquired before the marriage as being subject to division. All of these can be better understood if you have a lawyer by your side.
