You are probably stuck. The only thing a Court could do for you is order a partition which would allow you to sell your portion of the property. If you cannot find a buyer for your portion well, there you have it. That being said, depending on how the property is titled, the Judge may not even be able to order a partition. You should really speak to a lawyer familiar with real estate and review your options with paperwork in hand. Good Luck.
So there is no misunderstanding, my answer to your question does not establish an attorney/client relationship with me or my firm and such a relationship will not be established unless and until you personally retain me or my firm to represent you.
It would be a good idea to have title check to see how the title was taken first. If it says Joint Tenants, JTWROS, or Joint Tenants with Full Rights of Survivorship, you may be out of luck, as only the survivor in such situation would own it and no names could be added without all three agreeing. If it says an Undivided 1/3 interest, as Tenants in Common, or just the three names you can try a partition action. I have had very good luck filing partition actions, getting courts to order facilitative mediation, and coming up with a price and payment plan for the siblings to do the buyout that makes sense. If it is Tenants in Common and any party is married you also have spouses to deal with in the picture.
You recitd what you want, but you did not state their intentions. The simple solution is that the three (3) of you should resolve to sell the property since none of you seemingly can individually afford to own the property.
Need more details but you have correctly defined your position, neither yourself nor another desires to own the property with your siblings. Sadly you have defined market.
This is the other side of the coin, you cannot force them to sell, they cannot force you to keep.
To the PROSPECTIVE client, please call myself or another attorney for your choice with more detaiils and an appointment. My PRELIMINARY answer to your question(s) is for general purposes and based upon what little information you have conveyed. It is based on such limited information that the general answer should never be relied as a reason for your action or inaction. My response does NOT establish an attorney-client relationship and such may only be established by mutual agreement, and the signing of a written retainer agreement, which will generally require payment for our services, as this is what we do for a living and, just like you, we must get paid for our work.. .
