I want to see if anyone here is or knows a real estate attorney or knows anything about trusts.

Long story short.

My dad dies in 04/09
09/09 when i get back from Iraq and my grand mother gives me and my brother two pieces of land. I(and my wife) take one and my brother takes the other.
11/10 my grand mother "does not remember" giving me the other piece of land.
12/10 I get letter from her attorney saying they want both pieces back, because "the deeds are not effective conveyances because the property had perviously been transferred into your grandmother's trust"
I call and they (attorney's para legal or who ever answered the phone) says it was part of a revokable trust.

She signed these to me and my brother on Quit Claim deeds signed at a notary.

This issue was facilitated by my aunts as my grandmother does not speak english, i don't speak spanish. I have a feeling they may be behind this some how.
