If your relation deteriorated to the point where your brother wants to evict you, is there a reason for both of you to go through a court?
If you are a tenant, and you pay rent month to month, and your rent month begins on the first day of the month, your brother may "terminate" your tenancy by a thirty day notice that would coincide with the last day of the following month. In February a termination notice would end your monthly tenancy on March 31, 2013. After that day, if you did not move out, he could start a court case.
You may have meritorious defenses to an eviction proceeding. A face to face conference with an attorney may help determine if you are owed wages and benefits, are a tenant, an employee or some other legal occupant of the house. A lawyer may tie your brother up in court defending you as a person who may not be evicted.
Do not sell your legal rights short. See an attorney.
