Answer

You do have a problem here. First, your Mother thought she was protecting her children here by having a will and giving this house to the both of you. WRONG. She did you no favors here because she SHOULD HAVE formed a Revocable Living Trust, transferred the house into the trust and her children could have sold the house. Now you and your brother must "probate the Estate," meaning that you both need to open a probate case and should probably seek Attorney counsel for this process. Probate fees are high so be prepared, but that is the only way you can eventually get title.

Also, while it's nice that your brother kept up the payments I suspect he'll want a larger percentage of the house because of his financial commitment. I hope you can agree. You and your brother had better work efficiently with your chosen Attorney and if you think you can do it yourself, you are living in dreamland. It is that complicated and a Probate Judge will dismiss your action if proper procedures are not met. Further, any Paralegal that doesn't know to direct someone to an Attorney, especially in complicated issues like Probate, should be prohibited from practicing. I am outraged that a Paralegal would not tell you emphatically that preparing deeds would do you no good because the one signature that is paramount on any deed is the transferor and that is your deceased Mother.
