You need to file as soon as possible. The 3 month will play in your favor. Unfortunetly, when you get divorced in Indiana all property goes into the marital pot. If she will sign off of the things you owned before marriage you can do it that way, but it sounds like she is not going to do that.
By moving her into the house you comingled it and made it marital property. However, it can be argued that she should not gain from a 3 month marriage. The best thing you have on your side for this argument is time, so act fast. I suggest you call a local attorney today.
