There are two fundamental issues here.
1. The division of marital assets and whether the house is considered a marital asset.
2. Whether you are entitled to spousal support.
To answer these questions accurately, I would have to examine the prenuptial agreement you signed and find out more details about the circumstances around which you were asked to sign this prenuptial agreement. It is also essential to ascertain how title to the property is held and whether you can document the actual contributions you made to the house and the mortgage.
Concerning the second question of spousal support, if there is a significant discrepancy between your income and his, and the standard of living that you have maintained as a family cannot be supported on your income, you will most likely be granted some spousal support for a while.
If you are living in the New York City metropolitan area, I strongly suggest that you call me at 212-370-1660 to discuss the matter at greater length.
