Can I sue for sabotage of partner is not moving forward with agreed business plans?

The answer depends upon the business arangement you had with your "partner".  Was a formal business entity established to govern your partnership or to own the property?  If so the foundational documents of that entity (LLC - operating agreement, Partnership Agreement, Inc. - By laws) will likely direct what rights you have.  To the extent there is no business entity and there were only verbal agreements, you may have a claim for promissory estoppel, breach of contract or unjust enrichment.  Just depends upon the circumstances.  In any event, sending a demand letter from an attorney laying out his/her malfeasance and explaining your rights might get the partner to start acting more reasonably. Feel free to contact me if you would like to discuss more.
