I am sorry for the situation you currently find yourself in. I am also somewhat confused by the fact pattern you present. if the house is jointly held between you and your mother than what your siblings want will be of no consequence. However, if she "signed a paper and gave them the house" you need to be specify what document was signed and what it purported to say. if you own one half of the house you would have to consent to transferring title to your siblings (at least as to your half). Have they formally commenced litigation? Was your mother of sound mind when she (allegedly) signed the house into the siblings names. I strongly enourage you to gather all of the information and present it to your attorney for review. it may seem overwhelming at times, especially if you are in this by yourself against your siblings, but the most important consideration is that your mothers wishes be followed. Good luck!
