Law / My wife's signature has been forged relating to a Polish will, is it worth hiring a lawyer? [16]

I have lived in the U.S. all my life and was fortunate enough to have met my wife during a 1997 visit to Poland. We live in the U.S. and in 2002 her dad passed away. In 2007 her step mother passed away after suffering from a stroke that she had in 2006. My wife lost her real mother during birth and at the age of 2 found her step mother that took care of her till we met. She was the only child to either mother.

The father left half of his will to the step mother and half to my wife. The step mother had signed her "will" over to her relatives 3 months before her death. She was in no condition to sign or make any decisions because her health was very bad. The relatives bribed/manipulated a notary to stamp the "will" and lied about where my wife lived and forged her signature to keep court papers away from her. My wife never received the court documents that would have enabled her to contest and/or check her step mothers mental state by a doctor. The relatives were dumb enough to have the documents come to their address and told the court my wife lived there. These people are known to have manipulated 3 other families out of their will also.

My question is, would it be worth hiring a lawyer in Poland and teaching these folks some manners. Is this case winnable and are Poland's laws stiff and strict on forgery in cases like this. In the U.S.A. it would but I am not so sure about Poland since there are stories of corruption still going on over there. The general area is Kolbuszowa. There is much more to this story but I tried to keep it as short as possible. Thanks for reading=)
