If you are one of the heirs then you're now a co-owner of the home and cannot be forced to leave. However any other co-owner can force the sale of the property in which case you would get your share of the proceeds, but would be forced to leave. Depending on when you paid the taxes or insurance you can be reimbursed, you'd be fully reimbursed before the succession was completed from the estate, you'd be reimbursed by the other co-owners for their share of the ownership costs after the succession is completed. The cost of the succession is a debt of the estate and can be paid by the estate. I can't comment of whether your brother can use that appraisal in court because I don't have enough information about that. Generally all property is restricted to specific uses depending on what kind of property it is and the incorrect address may not be a problem if the legal description is correct.

You do not state whether your mother was married at her death or whether she died with or without a will. If she died with a Will, then look to the Will to see who receives the property and in what capacity. Forced heirship rights, if any, could change this. If she died intestate i.e. without a Will, then you will be a co-owner of the property. Also, if she died intestate then your neices and nephews will inherit by representation from your predeceased sister.
Has your brother been appointed as administrator of the Succession by the Court? You may want to check this out as the administrator has substantial control over the proceedings. Hope this helps.
