From what I gather, your prenuptial requires him to put your name on the deed & he is refusing to do so - correct? Assuming same to be the case, it is advisable you retain an attorney at the least to draw his attention (in writing) to his default/violation of the agreement. That said, you should bring the agreement in to a NYC Matrimonial attorney for a full assessment of the issue.

You can bring an action to enforce the terms of the prenuptial agreement. Consult with an attorney to assist you and bring all the paperwork with you for the consultation.

The short answer is maybe. I think your question doesn't address what it is that you hope to do - are you seeking to enforce the terms or invalidate the prenup (if a divorce were to occur). Seek out some lawyers to review your agreement and explore your options.
