First look in the phone book. There is a number for free legal advice. (like 211 or something, it's different for Orlando)
Second, count your blessings that he hasn't already evicted you, and know that he probably will. Be positive anyway and ask your Guardian Angel to help you stay positive! Good thoughts = good outcomes! :O) I PROMISE!
Third, I am unclear on wether he can "evict" you because you were not, nor ever, "renting" from him. If you can trace the check to your mother, you may have a case for yourself, and for her intentions.
This is considered a "domestic dispute" so it's not all cut and dry, you may have a case, but you will have to find out from an attorney. We went through this with my Mother-In-Law.
Suggestion: When you do decide to move out, WHICH YOU SHOULD, (only if you can not take legal action or can not prove your mother's intent,) DO NOT TELL HIM.
Others may think this is the worst advice ever, however, this is what we did with my Mother-In-Law. I feared she would give us some rediculous amount of time to "get out" if we told her our intentions, and once she found out that's exactly what she did. She told us to get out by friday! A whole 3 days! Yippee! (we had a 4 month old too!and I was pregnant!)
Call Apartment Hunters and ask them about government subsidized housing. They should be able to point you in the right direction.
Also, there is nothing that says the appliances are his, so take them with you if you need them.
Know that you will feel anger and be upset, but do not let it consume you as I let it consume me (for 3 years!).
In addition to that ordeal, My uncle sold my grandmothers house in the same manner you are describing except that no one lived there when it happened. Because grandma died before gramps, his will had the final say, and my grandma's didn't.. so everything we were supposed to get turned into getting nothing.
My Uncle told my brother he was going to sell all their possessions and we should stop by the garage sale if we were interested in BUYING!!!! anything. He threw everything away!!!! Pictures of my deceased father, all her freakin dolls that were all COLLECTABLES, ect.
So know that you are not alone but your brother, should he choose to be greedy over loving his family, will have to answer to God in the end and that's his decision not yours.
I wish the very best for you and are in my prayers!
Love,
J.
